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.

- Connect some "TODO" receivers.
Test Plan:

Summary:
Ref T7199. This prepares for an exciting new world of more powerful "!action" commands. In particular:
- We parse multiple commands per mail.
- We parse command arguments (these are currently not used).
- We parse commands at the beginning or end of mail.
Additionally:
- Do a quick modernization pass on all handlers.
- Break legacy compatibility with really hacky Facebook stuff (see T1992). They've theoretically been on notice for a year and a half, and their setup relies on calling very old reply handler APIs directly.
- Some of these handlers had some copy/paste fluff.
- The Releeph handler is unreachable, but fix it //in theory//.
Test Plan:
- Sent mail to a file; used "!unsubscribe".
- Sent mail to a legalpad document; used "!unsubscribe".
- Sent mail to a task; used various "!close", "!claim", "!assign", etc.
- Sent mail to a paste.
- Sent mail to a revision; used various "!reject", "!claim", etc.
- Tried to send mail to a pull request but it's not actually reachable.

Summary:
Ref T7199. Although this is useful for discovery, it's un-useful enough that we already have an option to disable it, and most applications do not provide any meaningful instructions.
Throwing it away makes it easier to move forward and lets us get rid of a config option.
This is becoming a more advanced/power-user feature anyway, and the new syntax will be significantly more complex and hard to explain with a one-liner. I'm currently thinking that I'll maybe make the "help" menu a dropdown and give it some options like:
+---+
| O |
+---+---------------------+
| Maniphest Documentation |
| Maniphest Email Actions |
+-------------------------+
Then you click the "Email Actions" thing and get a runtime-derived list of available options. Not sure if I'll actually build that, but I think we can fairly throw the in-mail instructions away even if we don't go in that specific direction.
Test Plan: Grepped for `replyHandlerInstructions`, got no hits.

Summary: Fixes T7088. Mainly this updates the documentation but I also snuck in tweaking how the domain reply handler is built. This does two main things -- makes the behavior consistent as some applications who didn't override this behavior would send out emails with reply tos AND makes it easier for us to deprecate the custom domain thing on a per application basis, which is just silly. On that note, the main documentation doesn't get into how this can be overridden, though I left in that mini blurb on the config setting itself. We could deprecate this harder and LOCK things if you want as well.
Test Plan: read docs, looked good. reasoned through re-factor
