In our email mirror, we have a special format for missed
message emails that uses a 32-bit randomly generated token
that we put into redis that is then prefixed with "mm" for
a total of 34 characters.
We had a bug where we would mis-classify emails like
mmcfoo@example.com as being these system-generated emails
that were part of the redis setup.
It's actually a little unclear how the bug in the library
function would have manifested from the user's point of view,
but it was definitely buggy code, and it's possibly related in
a subtle way to an error report we got from a customer where
only one of their users, who happened to have a name like
mmcfoo, was having problems with the mirror.
This has the nice side effect of getting rid of the now-unnecessary
ADMIN_DOMAIN from this codepath -- we really just want whichever
realm ERROR_BOT is in.
This fixes a regression where missed message emails would not be sent
at all in the event that EMAIL_GATEWAY_PATTERN was unset.
The overall experience still isn't great, but it's better than crashing.
Fixes: #1411
[commit message expanded by tabbott]
This reverts commit f1f48f305e.
The use of sklearn unfortunately caused a substantial slowdown to the
Zulip provisioning process, which didn't seem worth it for a
relatively minor feature.
get_display_recipient's annotation clashes with other wrong annotations.
Fix those wrong annotations.
Since get_display_recipient returns a Union, use isinstance checks and
casts to make mypy checks succeed.
Prior to adding reply-to-missed-message-email functionality, adding
automated tests for simpler case - incoming stream messages. Added
to new file test_email_mirror.py.
Also removed the "if not body" code from process_stream_message that
will never run because of an upstream ZulipEmailForwardError exception.
The do_send_missedmessage_events_reply_in_zulip function in the email
mirror didn't support EMAIL_GATEWAY_PATTERN that wasn't of the form
%s@example.com (which resulted in replies to missed message emails failing
to be parsed).
* Fixes a few bugs with missed message address for PMs and huddles.
* Uses missed message address for all missed message reply-to headers on
the zulip.com realm.

The one time use address are a unique token which maps to stored stated
in redis. We store the user_id, recipient_id, and subject. When an email
is received at this address it is sent to the stored recipient by the
stored user. Anyone with this address can send a single message as this
user.

Previously, the email mirror queue worker used the API bindings to send
messages to Zulip, as if it were any other API client.
This is inefficient since we're running the worker inside the Django
context on a machine with database access; we can instead just use the
internal message-sending functions we use elsewhere. This also resolves
potential issues with SSL certificates, etc. that might occur when we
were previously making a HTTPS connection.

Here, we don't want to check the uploading users' realm when determining
message privacy, because that'll prevent non-Zulip users from having
email-mirror-uploaded images. Instead, we just pass along the target
realm for the message explicitly to upload_message_image()
