a09dc2d5c2 SECURITY: BCC active user emails from group SMTP (#19724)
When sending emails out via group SMTP, if we
are sending them to non-staged users we want
to mask those emails with BCC, just so we don't
expose them to anyone we shouldn't. Staged users
are ones that have likely only interacted with
support via email, and will likely include other
people who were CC'd on the original email to the
group.

DEV: Hash tokens stored from email_tokens (#14493)
This commit adds token_hash and scopes columns to email_tokens table.
token_hash is a replacement for the token column to avoid storing email
tokens in plaintext as it can pose a security risk. The new scope column
ensures that email tokens cannot be used to perform a different action
than the one intended.

To sum up, this commit:

* Adds token_hash and scope to email_tokens

* Reuses code that schedules critical_user_email

* Refactors EmailToken.confirm and EmailToken.atomic_confirm methods

* Periodically cleans old, unconfirmed or expired email tokens

FIX: Do not show recipient user in email participants list (#14642)
This commit removes the recipient's username from the
respond to / participants list that is shown at the bottom
of user notification emails. For example if the recipient's
username was jsmith, and there were participants ljones and
bmiller, we currently show this:

> "reply to this email to respond to jsmith, ljones, bmiller"

or

> "Participants: jsmith, ljones, bmiller"

However this is a bit redundant, as you are not replying to
yourself here if you are the recipient user. So we omit the
recipient user's username from this list, which is only used
in the text of the email and not elsewhere.

FEATURE: Use group SMTP job and mailer instead of UserNotifications change (#13489)
This PR backtracks a fair bit on this one https://github.com/discourse/discourse/pull/13220/files.

Instead of sending the group SMTP email for each user via `UserNotifications`, we are changing to send only one email with the existing `Jobs::GroupSmtpEmail` job and `GroupSmtpMailer`. We are changing this job and mailer along with `PostAlerter` to make the first topic allowed user the `to_address` for the email and any other `topic_allowed_users` to be the CC address on the email. This is to cut down on emails sent via SMTP, which is subject to daily limits from providers such as Gmail. We log these details in the `EmailLog` table now.

In addition to this, we have changed `PostAlerter` to no longer rely on incoming email email addresses for sending the `GroupSmtpEmail` job. This was unreliable as a user's email could have changed in the meantime. Also it was a little overcomplicated to use the incoming email records -- it is far simpler to reason about to just use topic allowed users.

This also adds a fix to include cc_addresses in the EmailLog.addressed_to_user scope.

FIX: Do not enqueue :group_smtp_email job if IMAP disabled for the group (#13307)
When a group only has SMTP enabled and not IMAP, we do not
want to enqueue the :group_smtp_email job because using the group's
SMTP credentials for sending user_private_message emails is
handled by the UserNotifications class.

We do not want the :group_smtp_email job to be enqueued because
that uses a reply key instead of the group.email_username
for the reply-to address which is not what we want for SMTP
only, and also creates an IncomingEmail record to prevent IMAP
double syncing which we do not need either.

There is an open question about what happens when IMAP is
enabled after SMTP has been enabled for a while, and also questions
around whether we could do away with :group_smtp_email altogether
and handle everything via EmailLog and UserNotifications, adding
additional columns to the former and modifying the Imap::Sync
class to take this into account...a lot more further testing
for IMAP needs to be done to answer those questions.

For now, this fix should be sufficient to get the correct
reply-to address for user_private_response messages sent in
response to emails sent directly to the group's
email_username SMTP address.

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: Improve group email settings UI (#13083)
This overhauls the user interface for the group email settings management, aiming to make it a lot easier to test the settings entered and confirm they are correct before proceeding. We do this by forcing the user to test the settings before they can be saved to the database. It also includes some quality of life improvements around setting up IMAP and SMTP for our first supported provider, GMail. This PR does not remove the old group email config, that will come in a subsequent PR. This is related to https://meta.discourse.org/t/imap-support-for-group-inboxes/160588 so read that if you would like more backstory.

### UI

Both site settings of `enable_imap` and `enable_smtp` must be true to test this. You must enable SMTP first to enable IMAP.

You can prefill the SMTP settings with GMail configuration. To proceed with saving these settings you must test them, which is handled by the EmailSettingsValidator.

If there is an issue with the configuration or credentials a meaningful error message should be shown.

IMAP settings must also be validated when IMAP is enabled, before saving.

When saving IMAP, we fetch the mailboxes for that account and populate them. This mailbox must be selected and saved for IMAP to work (the feature acts as though it is disabled until the mailbox is selected and saved):

### Database & Backend

This adds several columns to the Groups table. The purpose of this change is to make it much more explicit that SMTP/IMAP is enabled for a group, rather than relying on settings not being null. Also included is an UPDATE query to backfill these columns. These columns are automatically filled when updating the group.

For GMail, we now filter the mailboxes returned. This is so users cannot use a mailbox like Sent or Trash for syncing, which would generally be disastrous.

There is a new group endpoint for testing email settings. This may be useful in the future for other places in our UI, at which point it can be extracted to a more generic endpoint or module to be included.

FIX: Ensure group SMTP and message builder always uses from address for Reply-To when IMAP is enabled (#11037)
There is a site setting reply_by_email_enabled which when combined with reply_by_email_address creates a Reply-To header in emails in the format "test+%{reply_key}@test.com" along with a PostReplyKey record, so when replying Discourse knows where to route the reply.

However this conflicts with the IMAP implementation. Since we are sending the email for a group via SMTP and from their actual email account, we want all replys to go to that email account as well so the IMAP sync job can pick them up and put them in the correct place. So if the group has IMAP enabled and configured, then the reply-to header will be correct.

This PR also makes a further fix to 64b0b50 by using the correct recipient user for the PostReplyKey record. If the post user is used we encounter this error:

if destination.user_id != user.id && !forwarded_reply_key?(destination, user)
  raise ReplyUserNotMatchingError, "post_reply_key.user_id => #{destination.user_id.inspect}, user.id => #{user.id.inspect}"
end
This is because the user above is found from the from_address, but the destination which is the PostReplyKey is made by the post.user, which will be different people.

FIX: When admin changes an email for the user the user must confirm the change (#10830)
See https://meta.discourse.org/t/changing-a-users-email/164512 for additional context.

Previously when an admin user changed a user's email we assumed that they would need a password reset too because they likely did not have access to their account. This proved to be incorrect, as there are other reasons a user needs admin to change their email. This PR:

* Changes the admin change email for user flow so the user is sent an email to confirm the change
* We now record who the email change request was requested by
* If the requested by user is admin and not the user we note this in the email sent to the user
* We also make the confirm change email route open to anonymous users, so it can be clicked by the user even if they do not have access to their account. If there is a logged in user we make sure the confirmation matches the current user.

FEATURE: Allow email image embed with secure media (#10563)
This PR introduces a few important changes to secure media redaction in emails. First of all, two new site settings have been introduced:

* `secure_media_allow_embed_images_in_emails`: If enabled we will embed secure images in emails instead of redacting them.
* `secure_media_max_email_embed_image_size_kb`: The cap to the size of the secure image we will embed, defaulting to 1mb, so the email does not become too big. Max is 10mb. Works in tandem with `email_total_attachment_size_limit_kb`.

`Email::Sender` will now attach images to the email based on these settings. The sender will also call `inline_secure_images` in `Email::Styles` after secure media is redacted and attachments are added to replace redaction messages with attached images. I went with attachment and `cid` URLs because base64 image support is _still_ flaky in email clients.

All redaction of secure media is now handled in `Email::Styles` and calls out to `PrettyText.strip_secure_media` to do the actual stripping and replacing with placeholders. `app/mailers/group_smtp_mailer.rb` and `app/mailers/user_notifications.rb` no longer do any stripping because they are earlier in the pipeline than `Email::Styles`.

Finally the redaction notice has been restyled and includes a link to the media that the user can click, which will show it to them if they have the necessary permissions.

102909edb3 FEATURE: Add support for secure media (#7888)
This PR introduces a new secure media setting. When enabled, it prevent unathorized access to media uploads (files of type image, video and audio). When the `login_required` setting is enabled, then all media uploads will be protected from unauthorized (anonymous) access. When `login_required`is disabled, only media in private messages will be protected from unauthorized access. 

A few notes: 

- the `prevent_anons_from_downloading_files` setting no longer applies to audio and video uploads
- the `secure_media` setting can only be enabled if S3 uploads are already enabled and configured
- upload records have a new column, `secure`, which is a boolean `true/false` of the upload's secure status
- when creating a public post with an upload that has already been uploaded and is marked as secure, the post creator will raise an error
- when enabling or disabling the setting on a site with existing uploads, the rake task `uploads:ensure_correct_acl` should be used to update all uploads' secure status and their ACL on S3

Keep customizations very simple.

Customizations can be added and edited in Admin > Customize > Email Style.
