FIX: Handle forwarded email quotes around Reply-To display name (#14384)
The display name can have quotes around it, which does not work
with our current comparison of a from field (in this case Reply-To)
and another header (X-Original-From), because we are not comparing
the two values in the same way. This causes an issue where the
commit here: b88d8c8 will not
work properly; the forwarded email gets the From address instead
of the Reply-To address as intended.

FIX: Capture CC addresses for forwarded emails (#14254)
When forwarding emails into the group inbox, we now use the
original sender email as the from_address since
2ac9fd9dff. However, we have not
been saving the original CC addresses of the forwarded email,
which are needed to include those recipients in on the conversation
when replying via the group inbox.

This commit captures the CC addresses on the incoming email, and
makes sure the emails are created as staged users and added to the
list of topic allowed users so they are included on CC's sent by
the GroupSmtpEmail and other jobs.

FIX: Correct the forwarded by user small post for group inbox (#14252)
When 2ac9fd9dff was done, this
affected the small post that is created when forwarding an email
into the group inbox. Instead of using the name and the email of
the user who forwarded the email, it used the original from email
and name to create the small post. So instead of something like
"Discourse Team forwarded the above email" we ended up with
"John Smith forwarded the above email" which is incorrect.

This fixes the issue by creating a staged user for the forwarding
email address (if such a user does not yet exist) and uses that
for the "forwarded" small post instead.

FIX: Use original from address when forwarding to group inbox (#14114)
When emails were forwarded to a group inbox by the email address
of the group, for example when an email ends up in spam and must
be manually forwarded to the group+site@discoursemail.com address,
the OP of the topic ended up being the group's email address instead
of the sender who originally sent the email to the group inbox.

This commit detects that an email has been forwarded using existing
tools, and if the from address matches one of the group incoming
email addresses, then we look at the forwarded email's from address
and use that instead for the incoming email from address as well as
the staged/regular user used for the Topic.user.

This will make it much cleaner to forward emails into a group inbox,
and will prevent issues with PostAlerter where the OP is double-notified
for these emails.

FIX: Use reply-to address for incoming emails if present (#13896)
When the Reply-To header is present for incoming emails we
want to use it instead of the from address. This is usually the
case when forwarding an email via a mailing list into Discourse.

For now we are only using the Reply-To header if the email has
been forwarded via Google Groups, which is why we are checking the
X-Original-From header too. In future we may want to use the Reply-To
header in more cases.

FIX: Prevent resurrecting old topics via email reply for group inboxes with SMTP enabled (#13382)
We already reject email replies to public topics via `SiteSetting.disallow_reply_by_email_after_days` and raising the `OldDestinationError`. This PR introduces similar behaviour for group inboxes, but without the rejection, and **only when SMTP is enabled for the group**.

If a reply is sent via email and the post is older than `SiteSetting.disallow_reply_by_email_after_days` days ago, then we create a new topic instead of making a reply in the old one and link back to the original topic. This is done to prevent long running group inbox discussions.

FIX: Link up reply to post correctly when emailing group (#13339)
When replying to a user_private_message email originating from
a group PM that does _not_ have a reply key (e.g. when replying
directly to the group's SMTP address), we were mistakenly linking
the new post created from the reply to the OP and the user who
created the topic, based on the first IncomingEmail message ID in
the topic, rather than using the correct reply to user and post number
that the user actually replied to.

We now use the In-Reply-To header to look up the corresponding EmailLog
record when the user who replied was sent a user_private_message email,
and use the post from that as the reply_to_user/post.

This also removes superfluous filtering of incoming_email records. After
already filtering by message_id and then addressed_to_user (which only
returns incoming emails where the to, from, or cc address includes any
of the user's emails), we were filtering again but in the ruby code for
the exact same conditions. After removing this all existing tests still
pass.

FEATURE: Use group SMTP settings for sending user notification emails (initial) (#13220)
This PR changes the `UserNotification` class to send outbound `user_private_message` using the group's SMTP settings, but only if:

* The first allowed_group on the topic has SMTP configured and enabled
* SiteSetting.enable_smtp is true
* The group does not have IMAP enabled, if this is enabled the `GroupSMTPMailer` handles things

The email is sent using the group's `email_username` as both the `from` and `reply-to` address, so when the user replies from their email it will go through the group's SMTP inbox, which needs to have email forwarding set up to send the message on to a location (such as a hosted site email address like meta@discoursemail.com) where it can be POSTed into discourse's handle_mail route.

Also includes a fix to `EmailReceiver#group_incoming_emails_regex` to include the `group.email_username` so the group does not get a staged user created and invited to the topic (which was a problem for IMAP), as well as updating `Group.find_by_email` to find using the `email_username` as well for inbound emails with that as the TO address.

#### Note

This is safe to merge without impacting anyone seriously. If people had SMTP enabled for a group they would have IMAP enabled too currently, and that is a very small amount of users because IMAP is an alpha product, and also because the UserNotification change has a guard to make sure it is not used if IMAP is enabled for the group. The existing IMAP tests work, and I tested this functionality by manually POSTing replies to the SMTP address into my local discourse.

There will probably be more work needed on this, but it needs to be tested further in a real hosted environment to continue.

FEATURE: new 'trim_incoming_emails' site setting (#12874)
This setting allows admin to de/activate automatic trimming of incoming email.
There are instances where it does wonders in trimming all the garbage content and other
instances where it's so bad that it trims the most important part of the email.

FIX: don't remove hidden content using the style attribute when converting HTML to Markdown.
The regexp used was doing more harm than good. It was way too broad.

FIX: properly elide signatures from emails sent with Front App.
This is fairly safe as Front App nicely identifies signatures in the HTML part.

FIX: IMAP allow unknown senders to reply to group topics via email (#11877)
Adds a new column/setting to groups, allow_unknown_sender_topic_replies, which is default false. When enabled, this scenario is allowed via IMAP:

* OP sends an email to the support email address which is synced to a group inbox via IMAP, creating a group topic
* Group user replies to the group topic
* An email notification is sent to the OP of the topic via GroupSMTPMailer
* The OP has several email accounts and the reply is sent to all of them, or they forward their reply to another email account
* The OP replies from a different email address than the OP (gloria@gmail.com instead of gloria@hey.com for example)
* The a new staged user is created, the new reply is accepted and added to the topic, and the staged user is added to the topic allowed users

Without allow_unknown_sender_topic_replies enabled the new reply creates an entirely new topic (because the email address it is sent from is not previously part of the topic email chain).
