Summary:
Depends on D20012. Ref T920. If you have a test adapter configured, it should swallow messages and prevent them from ever hitting a lower-priority adapter.

f0c6ee4823 Add "Contact Numbers" so we can send users SMS mesages
Summary:
Ref T920. To send you SMS messages, we need to know your phone number.

This adds bare-bone basics (transactions, storage, editor, etc).

From here:

**Disabling Numbers**: I'll let you disable numbers in an upcoming diff.

**Primary Number**: I think I'm just going to let you pick a number as "primary", similar to how email works. We could imagine a world where you have one "MFA" number and one "notifications" number, but this seems unlikely-ish?

**Publishing Numbers (Profile / API)**: At some point, we could let you say that a number is public / "show on my profile" and provide API access / directory features. Not planning to touch this for now.

**Non-Phone Numbers**: Eventually this could be a list of other similar contact mechanisms (APNS/GCM devices, Whatsapp numbers, ICQ number, twitter handle so MFA can slide into your DM's?). Not planning to touch this for now, but the path should be straightforward when we get there. This is why it's called "Contact Number", not "Phone Number".

**MFA-Required + SMS**: Right now, if the only MFA provider is SMS and MFA is required on the install, you can't actually get into Settings to add a contact number to configure SMS. I'll look at the best way to deal with this in an upcoming diff -- likely, giving you partial access to more of Setings before you get thorugh the MFA gate. Conceptually, it seems reasonable to let you adjust some other settings, like "Language" and "Accessibility", before you set up MFA, so if the "you need to add MFA" portal was more like a partial Settings screen, maybe that's pretty reasonable.

**Verifying Numbers**: We'll probably need to tackle this eventually, but I'm not planning to worry about it for now.

5537e29ee8 Move "Welcome" mail generation out of PhabricatorUser
Summary:
Ref PHI1027. Currently, `PhabricatorUser` has a couple of mail-related methods which shouldn't really be there in the long term. Immediately, I want to make some adjusments to the welcome email.

Move "Welcome" mail generation to a separate class and consolidate all the error handling. (Eventually, "invite" and "verify address" email should move to similar subclasses, too.) Previously, a bunch of errors/conditions got checked in multiple places.

The only functional change is that we no longer allow you to send welcome mail to disabled users.

Test Plan:
  - Used "Send Welcome Mail" from profile pages to send mail.
  - Hit "not admin", "disabled user", "bot/mailing list" errors.
  - Used `scripts/user/add_user.php` to send welcome mail.
  - Used "Create New User" to send welcome mail.
  - Verified mail with `bin/mail show-outbound`. (Cleaned up a couple of minor display issues here.)

ff220acae6 Don't bounce mail messages if any recipient was reserved
Summary:
Ref T13222. If we receive a message and nothing processes it, we normally try to send the user an error message like "hey, nothing handled this, maybe you got the address wrong".

Just skip the "send them an error message" part if any recipient was reserved, so if you "Reply All" to a message that is "From: noreply@phabricator" you don't get a relatively unhelpful error.

This also makes sure that the "void" address doesn't generate bounces if the "From" is a valid user email address (e.g., with `metamta.can-send-as-user`). That is:

  - Phabricator needs to send a mail with only "CC" users.
  - Phabricator puts the "void" address in "To" as a placeholder.
  - The "void" address happens to route back to Phabricator.

We don't want that mail to bounce to anywhere. Normally, it won't:

  - From is usually "noreply@phabricator", which isn't a user, so we won't send anything back: we only send mail to verified user email addresses.
  - The message will have "X-Phabricator-Sent-This-Message: true" so we won't process it at all.

...but this is another layer of certainty.

Test Plan: Used `bin/mail receive-test` to receive mail to an invalid, unreserved address (bounce/error email) and an invalid, reserved address (no bounce/error email).

b5797ce60a Refactor mail to produce an intermediate "bag of strings" object in preparation for SMS
Summary:
Depends on D19954. Ref T920. This is a step toward a world where "Mailers" are generic and may send messages over a broader array of channels (email, SMS, postal mail).

There are a few major parts here:

  - Instead of calling `$mailer->setSubject()`, `$mailer->setFrom()`, etc., build in intermediate `$message` object first, then pass that to the mailer.
    - This breaks every mailer! This change on its own does not fix them. I plan to fix them in a series of "update mailer X", "update mailer Y" followups.
    - This generally makes the API easier to change in the far future, and in the near future supports mailers accepting different types of `$message` objects with the same API.
  - Pull the "build an email" stuff out into a `PhabricatorMailEmailEngine`. `MetaMTAMail` is already a huge object without also doing this translation step. This is just a separation/simplification change, but also tries to fight against `MetaMTAMail` getting 5K lines of email/sms/whatsapp/postal-mail code.
  - Try to rewrite the "build an email" stuff to be a bit more straightforward while making it generate objects. Prior to this change, it had this weird flow:

```lang=php
foreach ($properties as $key => $prop) {
  switch ($key) {
    case 'xyz':
      // ...
  }
}
```

This is just inherently somewhat hard to puzzle out, and it means that processing order depends on internal property order, which is quite surprising.

Test Plan: This breaks everything on its own; adapters must be updated to use the new API. See followups.

a37b28ef79 Prevent inbound processing of the "void/placeholder" address and other reserved addresses
Summary:
Depends on D19952. Ref T13222. Never process mail targets if they match:

  - The "default" address which we send mail "From".
  - The "void" address which we use as a placholder "To" when we only have "CC" addresses.
  - Any address from a list of reserved/administrative names.

The first two prevent loops. The third one prevents abuse.

There's a reasonably well-annotated list of reservations and reasons here:

https://webmasters.stackexchange.com/questions/104811/is-there-any-list-of-email-addresses-reserved-because-of-security-concerns-for-a

Stuff like `support@` seems fine; stuff like `ssladmin@` might let you get SSL certs issued for a domain you don't control.

Also, forbid users from creating application emails with these reserved addresses.

Finally, build the default and void addresses somewhat more cleverly.

Test Plan: Added unit tests, tried to configured reserved addresses, hit the default/void cases manually with `bin/mail receive-test`.

e3aa043a02 Allow multiple mail receivers to react to an individual email
Summary:
Fixes T7477. Fixes T13066. Currently, inbound mail is processed by the first receiver that matches any "To:" address. "Cc" addresses are ignored.

**To, CC, and Multiple Receivers**

Some users would like to be able to "Cc" addresses like `bugs@` instead of having to "To" the address, which makes perfect sense. That's the driving use case behind T7477.

Since users can To/Cc multiple "create object" or "update object" addresses, I also wanted to make the behavior more general. For example, if you email `bugs@` and also `paste@`, your mail might reasonably make both a Task and a Paste. Is this useful? I'm not sure. But it seems like it's pretty clearly the best match for user intent, and the least-surprising behavior we can have. There's also no good rule for picking which address "wins" when two or more match -- we ended up with "address order", which is pretty arbitrary since "To" and "Cc" are not really ordered fields.

One part of this change is removing `phabricator.allow-email-users`. In practice, this option only controlled whether users were allowed to send mail to "Application Email" addresses with a configured default author, and it's unlikely that we'll expand it since I think the future of external/grey users is Nuance, not richer interaction with Maniphest/Differential/etc. Since this option only made "Default Author" work and "Default Author" is optional, we can simplify behavior by making the rule work like this:

  - If an address specifies a default author, it allows public email.
  - If an address does not, it doesn't.

That's basically how it worked already, except that you could intentionally "break" the behavior by not configuring `phabricator.allow-email-users`. This is a backwards compatility change with possible security implications (it might allow email in that was previously blocked by configuration) that I'll call out in the changelog, but I suspect that no installs are really impacted and this new behavior is generally more intuitive.

A somewhat related change here is that each receiver is allowed to react to each individual email address, instead of firing once. This allows you to configure `bugs-a@` and `bugs-b@` and CC them both and get two tasks. Useful? Maybe not, but seems like the best execution of intent.

**Sender vs Author**

Adjacently, T13066 described an improvement to error handling behavior here: we did not distinguish between "sender" (the user matching the email "From" address) and "actor" (the user we're actually acting as in the application). These are different when you're some internet rando and send to `bugs@`, which has a default author. Then the "sender" is `null` and the "author" is `@bugs-robot` or whatever (some user account you've configured).

This refines "Sender" vs "Author". This is mostly a purity/correctness change, but it means that we won't send random email error messages to `@bugs-robot`.

Since receivers are now allowed to process mail with no "sender" if they have some default "actor" they would rather use instead, it's not an error to send from an invalid address unless nothing processes the mail.

**Other**

This removes the "abundant receivers" error since this is no longer an error.

This always sets "external user" mail recipients to be unverified. As far as I can tell, there's no pathway by which we send them email anyway (before or after this change), although it's possible I'm missing something somewhere.

Test Plan:
I did most of this with `bin/mail receive-test`. I rigged the workflow slightly for some of it since it doesn't support multiple addresses or explicit "CC" and adding either would be a bit tricky.

These could also be tested with `scripts/mail/mail_handler.php`, but I don't currently have the MIME parser extension installed locally after a recent upgrade to Mojave and suspect T13232 makes it tricky to install.

- Ran unit tests, which provide significant coverage of this flow.
- Sent mail to multiple Maniphest application emails, got multiple tasks.
- Sent mail to a Maniphest and a Paste application email, got a task and a paste.
- Sent mail to a task.
  - Saw original email recorded on tasks. This is a behavior particular to tasks.
- Sent mail to a paste.
- Sent mail to a mock.
- Sent mail to a Phame blog post.
- Sent mail to a Legalpad document.
- Sent mail to a Conpherence thread.
- Sent mail to a poll.
- This isn't every type of supported object but it's enough of them that I'm pretty confident I didn't break the whole flow.
- Sent mail to an object I could not view (got an error).
- As a non-user, sent mail to several "create an object..." addresses.
  - Addresses with a default user worked (e.g., created a task).
  - Addresses without a default user did not work.

73e3057c52 Rename "MetaMTA" mail attachments and add more mail message objects
Summary:
Depends on D19953. Ref T9141. We have a "MetaMTAAttachment" object, rename it to "MailAttachment".

Also add a "Header" object and an "EmailMessage" object. Currently, mail adapters have a large number of methods like `setSubject()`, `addTo()`, etc, that I would like to remove.

I'd like the API to be more like `sendMessage(PhabricatorMailExternalMessage $message)`. This is likely a significant simplification anyway, since the implementations of all these methods are just copy/pasted boilerplate anyway (lots of `$this->subject = $subject;`) and this will let Adapters support other message media (SMS, APNS, Whatsapp, etc.)

That's a larger change, but move toward a world where we can build a concrete `$message` object for "email" or "sms".

The `PhabricatorMailEmailMessage` object is just a dumb, flat object representation of the information an adapter needs to actually send mail. The existing `PhabricatorMetaMTAMail` is a much more complex object and has a lot of rich data (delivery status, related object PHIDs, etc) and is a storage object.

The new flow will be something like:

  - `PhabricatorMetaMTAMail` (possibly renamed) is the storage object for any outbound message on this channel. It tracks message content, acceptable delivery media (SMS vs email), delivery status, related objects, has a PHID, and has a daemon worker associated with delivering it.
  - It builds a `PhabricatorMailExternalMessage`, which is a simple, flat description of the message it wants to send. The subclass of this object depends on the message medium. For email, this will be an `EmailMessage`. This is just a "bag of strings" sort of object, with appropriate flattened values for the adapter to work with (e.g., Email has email addresses, SMS has phone numbers).
  - It passes the `ExternalMessage` (which is a `MailMessage` or `SMSMessage` or whatever) to the adapter.
  - The adapter reads the nice flat properties off it and turns them into an API request, SMTP call, etc.

This is sort of how things work today anyway. The major change is that I want to hand off a "bag of strings" object instead of calling `setX()`, `setY()`, `setZ()` with each individual value.

Test Plan: Grepped for `MetaMTAAttachment`. This doesn't change any behavior yet.

84f94994ad Remove "metamta.insecure-auth-with-reply-to" Config option
Summary:
Ref T7477. This option was added in D842 in 2011, to support a specific narrow use case at Quora with community moderators using some kind of weird Gmail config.

I don't recall it ever coming up since then, and a survey of a subset of hosted instances (see T11760) reveals that no instances are using this option today. Presumably, even Quora has completed the onboarding discussed in D842, if they still use Phabricator. This option generally does not seem very useful outside of very unusual/narrow cases like the one Quora had.

This would be relatively easy to restore as a local patch if installs //do// need it, but I suspect this has no use cases anywhere.

Ref T920. Ref T7477. We currently drop empty mail only once it reaches the `ReplyHandler` layer.

I think no plausible receiver can ever do anything useful with this kind of mail, so we can safely drop it earlier and simplify some of the logic. After T7477, we'd end up throwing multiple exceptions if you sent empty mail to several valid receivers.

(I also want to move away from APIs oriented around raw addresses in more specialized layers, and this is one of the few callsites for raw mail address information.)

This requires updating some unit tests to actually have message bodies, since they failed with this error before hitting the other errors otherwise.

Test Plan: Used `bin/mail receive-test` to send empty mail, got appropriate "err:empty" out of it.

93e6dc1c1d Upgrade object reply addresses to SHA256 and remove "phabricator.mail-key"
Summary:
Ref T12509.

  - Upgrade an old SHA1 to SHA256.
  - Replace an old manually configurable HMAC key with an automatically generated one.

This is generally both simpler (less configuration) and more secure (you now get a unique value automatically).

This causes a one-time compatibility break that invalidates old "Reply-To" addresses. I'll note this in the changelog.

If you leaked a bunch of addresses, you could force a change here by mucking around with `phabricator_auth.auth_hmackey`, but AFAIK no one has ever used this value to react to any sort of security issue.

(I'll note the possibility that we might want to provide/document this "manually force HMAC keys to regenerate" stuff some day in T6994.)

Test Plan: Grepped for removed config. I'll vet this pathway more heavily in upcoming changes.

a0668df75a Remove "metamta.domain" and "metamta.placeholder-to-recipient" config options
Summary:
Ref T920. This simplifies mail configuration.

The "metamta.domain" option is only used to generate Thread-ID values, and we just need something that looks like a bit like a domain in order to make GMail happy. Just use the install domain. In most cases, this is almost certainly the configured value anyway. In some cases, this may cause a one-time threading break for existing threads; I'll call this out in the changelog.

The "metamta.placeholder-to-recipient" is used to put some null value in "To:" when a mail only has CCs. This is so that if you write a local client mail rule like "when I'm in CC, burn the message in a fire" it works even if all the "to" addresses have elected not to receive the mail. Instead: just send it to an unlikely address at our own domain.

I'll add some additional handling for the possiblity that we may receive this email ourselves in the next change, but it overlaps with T7477.

Test Plan: Grepped for these configuration values.

11cf8f05b1 Remove "getApplicationTransactionObject()" from ApplicationTransactionInterface
Summary:
Depends on D19919. Ref T11351. This method appeared in D8802 (note that "get...Object" was renamed to "get...Transaction" there, so this method was actually "new" even though a method of the same name had existed before).

The goal at the time was to let Harbormaster post build results to Diffs and have them end up on Revisions, but this eventually got a better implementation (see below) where the Harbormaster-specific code can just specify a "publishable object" where build results should go.

The new `get...Object` semantics ultimately broke some stuff, and the actual implementation in Differential was removed in D10911, so this method hasn't really served a purpose since December 2014. I think that broke the Harbormaster thing by accident and we just lived with it for a bit, then Harbormaster got some more work and D17139 introduced "publishable" objects which was a better approach. This was later refined by D19281.

So: the original problem (sending build results to the right place) has a good solution now, this method hasn't done anything for 4 years, and it was probably a bad idea in the first place since it's pretty weird/surprising/fragile.

Note that `Comment` objects still have an unrelated method with the same name. In that case, the method ties the `Comment` storage object to the related `Transaction` storage object.

Test Plan: Grepped for `getApplicationTransactionObject`, verified that all remaining callsites are related to `Comment` objects.

Summary:
Ref T13216. See PHI985. This config option once controlled adding a Herald transcript link to email. However, this was never implemented in a generic way and was removed from revisions in D8459 and from commits in D10705. No one has noticed or asked for this option for several years, so this is probably a good opportunity to simplify the software and reduce the total amount of configuration.

If we did want to pursue this in the future, I'd generally prefer to make it part of the mail detail page (`/mail/detail/12345/`) anyway.

6011085b0f Respect "metamta.email-body-limit" when building mail HTML bodies
Summary:
Ref T13151. See T11767. See PHI686. Although we limit outbound mail text bodies, the limit doesn't currently apply to attachments, HTML bodies, or headers. T11767 discusses improving this in the general case.

In the wild, an install hit an issue (see PHI686) where edits to Phriction pages generate very large HTML bodies. Check and respect the limit when building HTML bodies.

If we don't have enough room for the HTML body, we just drop it. We have the text body to fall back to, and HTML is difficult to truncate safely.

62a402491a Allow encrypted mail to be more specific about which object is affected
Summary:
Depends on D19487. Ref T13151. See PHI647. For some objects, like revisions, we can build slightly more useful secure email without actually disclosing anything.

In the general case, the object monogram may disclose information (`#acquire-competitor`) but most do not, so applications can whitelist an acceptable nondisclosing subject and link.

Support doing this, and make Differential do it. When we don't have a whitelisted URI but do know the object the mail is about, include a generic PHID-based URI; these are always nondisclosing.

Test Plan:
  - Without the Differential changes, sent normal mail (no changes) and secure mail (new generic PHID-based link).
  - With the Differential changes, sent secure mail; got richer subject and body link.

1b24b486f5 Manage object mailKeys automatically in Mail instead of storing them on objects
Summary:
Ref T13065. `mailKey`s are a private secret for each object. In some mail configurations, they help us ensure that inbound mail is authentic: when we send you mail, the "Reply-To" is "T123+456+abcdef".

  - The `T123` is the object you're actually replying to.
  - The `456` is your user ID.
  - The `abcdef` is a hash of your user account with the `mailKey`.

Knowing this hash effectively proves that Phabricator has sent you mail about the object before, i.e. that you legitimately control the account you're sending from. Without this, anyone could send mail to any object "From" someone else, and have comments post under their username.

To generate this hash, we need a stable secret per object. (We can't use properties like the PHID because the secret has to be legitimately secret.)

Today, we store these in `mailKey` properties on the actual objects, and manually generate them. This results in tons and tons and tons of copies of this same ~10 lines of code.

Instead, just store them in the Mail application and generate them on demand. This change also anticipates possibly adding flags like "must encrypt" and "original subject", which are other "durable metadata about mail transmission" properties we may have use cases for eventually.

Test Plan:
  - See next change for additional testing and context.
  - Sent mail about Herald rules (next change); saw mail keys generate cleanly.
  - Destroyed a Herald rule with a mail key, saw the mail properties get nuked.
  - Grepped for `getMailKey()` and converted all callsites I could which aren't the copy/pasted boilerplate present in 50 places.
  - Used `bin/mail receive-test --to T123` to test normal mail receipt of older-style objects and make sure that wasn't broken.

ffcfc04652 Add some delivery diagnostic headers to outbound mail
Summary:
Fixes T13087. Ref T13090. An install ran into a situation where mail was being double-delivered, and it wasn't immediately clear where in the pipeline the issue lay.

This change adds some headers which should rule out (or, at least, render very unlikely) some possible causes if we encounter similar issues in the future.

The `X-Phabricator-Mail-ID` header stores the ID of the `MetaMTAMail` storage object so we can distinguish between two messages sent to two different targets and one message which may have been split or re-sent. It also makes it easier to know what to `bin/mail show-outbound --id <id>` and where to find the message in the web UI for additional information.

The `X-Phabricator-Send-Attempt` is a unique value per attempt. If two mail messages are delivered with the same attempt value, the split is probably downstream from Phabricator. If they have different attempt values, the split is probably in Phabricator.

(In this case, the split was somewhere downstream from us, since sending mail with `/usr/bin/mail` also resulted in duplicates.)

Test Plan: Send some mail, inspected it with `bin/mail show-outbound --id <id>`, saw new headers with sensible/expected values.
