Our old group SMTP SSL option was a checkbox,
but this was not ideal because there are actually
3 different ways SSL can be used when sending
SMTP:
* None
* SSL/TLS
* STARTTLS
We got around this before with specific overrides
for Gmail, but it's not flexible enough and now people
want to use other providers. It's best to be clear,
though it is a technical detail. We provide a way
to test the SMTP settings before saving them so there
should be little chance of messing this up.
This commit also converts GroupEmailSettings to a glimmer
component.
Followup 7b627dc14b
In this other commit, I changed the email settings validator
to always use the `login` authentication method for
office365 and outlook, but I didn't change the actual
group SMTP mailer to do this.
This commit fixes that issue and does some minor refactoring.
In 958437e7dd we ensured that the email summaries are properly sent based on 'digest_attempted_at' for people who barely/never visit the forum.
This fixed the "frequency" of the email summaries but introduced a bug where the digest would be sent even though there wasn't anything new since for some users.
The logic we use to compute the threshold date for the content to be included in the digest was
```ruby
@since = opts[:since] || user.last_seen_at || user.user_stat&.digest_attempted_at || 1.month.ago
```
It was working as expected for users who haven never been seen but for users who have connected at least once, we would use their "last_seen_at" date as the "threshold date" for the content to be sent in a summary 😬
This fix changes the logic to be the most recent date amongst the `last_seen_at`, `digest_attempted_at` and `1.month.ago` so it's correctly handling cases where
- user has never been seen nor emailed a summary
- user has been seen in a while but has recently been sent a summary
- user has been sent a summary recently but hasn't been seen in a while.
For e-mails, secure uploads redacts all secure images, and later uses the access control post to re-attached allowed ones. We pass the ID of this post through the X-Discourse-Post-Id header. As the name suggests, this assumes there's only ever one access control post. This is not true for activity summary e-mails, as they summarize across posts.
This adds a new header, X-Discourse-Post-Ids, which is used the same way as the old header, but also works for the case where an e-mail is associated with multiple posts.
When sending SMTP for group SMTP functionality, we
are running into timeouts for both read and open
when sending mail occassionally, which can cause issues
like the email only being sent to _some_ of the recipients
or to fail altogether.
The defaults of 5s are too low, so bumping them up to
the defaults of the `net-smtp` gem.
Why this change?
Prior to this change, the ordering of the tags shown in the email subject
was non-deterministic as there was no specific order specified. This
problem was exposed by a flaky test which we had.
What is the fix?
This commit orders the tags used in the email subject first by the
`Tag#public_topic_count` column in descending order and then the `Tag#name`
column in ascending order.
Previously, it will add a "Re:" prefix to all the emails passing through the group SMTP mailer. It's creating confusion while receiving the mail for the first time on a PM.
* FEATURE: Implement max_tags_per_email_subject
* made it so only max_tags_per_email_subject is responsible for tags in emails when the feature is enabled
* added locales for implemented siteSettings
* reworded locale for enable_max_tags_per_email_subject
* added min value for max_tags_per_email_subject
* Implemented suggested changes to spec description
This commit fixes an issue where the Likes Received notification
count in the user digest email was not affected by the
since/last_seen date for the user, which meant that no matter
how long it had been since the user visited the count was
always constant.
Now instead for the Likes Received count, we only count the
unread notifications of that type since the user was last
seen.
The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.
There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.
This commit does a couple of things:
1. Changes the limit of tags to include a subject for a
notification email to the `max_tags_per_topic` setting
instead of the arbitrary 3 limit
2. Adds both an X-Discourse-Tags and X-Discourse-Category
custom header to outbound emails containing the tags
and category from the subject, so people on mail clients
that allow advanced filtering (i.e. not Gmail) can filter
mail by tags and category, which is useful for mailing
list mode users

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.

When sending emails with delivery_method_options -> return_response
set to true, the SMTP sending code inside Mail will return the SMTP
response when calling deliver! for mail within the app. This commit
ensures that Email::Sender captures this response if it is returned
and stores it against the EmailLog created for the sent email.
A follow up PR will make this visible within the admin email UI.
When we build and send emails using MessageBuilder and Email::Sender
we add custom headers defined in SiteSetting.email_custom_headers.
However this was causing errors in cases where the custom headers
defined a header that we already specify in outbound emails (e.g.
the Precedence: list header for topic/post emails).
This commit makes it so we always use the header value defined in Discourse
core if there is a duplicate, discarding the custom header value
from the site setting.
cf. https://meta.discourse.org/t/email-notifications-fail-if-duplicate-headers-exist/222960/14
* Adds a hidden site setting: `max_participant_names`
* Replaces duplicate code in `GroupSmtpMailer` and `UserNotifications`
* Groups are sorted by the number of users (decreasing)
* Replaces the query to count users of each group with `Group#user_count`)
* Users are sorted by their last reply in the topic (most recent first)
* Adds lots of tests
This commit allows group SMTP emails to be sent with a
different from email address that has been set up as an
alias in the email provider. Emails from the alias will
be grouped correctly using Message-IDs in the mail client,
and replies to the alias go into the correct group inbox.
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
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.
When the Forever option is selected for suspending a user, the user is suspended for 1000 years. Without customizing the site’s text, this time period is displayed to the user in the suspension email that is sent to the user, and if the user attempts to log back into the site. Telling someone that they have been suspended for 1000 years seems likely to come across as a bad attempt at humour.
This PR special case messages when a user suspended or silenced forever.
We now use the group's full name in group SMTP emails, so we are dropping the via #{site_name}. If group owners still want this they can just change the full name of the group.
We do not want to show the In Reply To section of the
group SMTP email template, it is similar to Context Posts
which we removed and is unnecessary.
This PR also removes the link to staged user profiles in
the email; their email addresses will just be converted
to regular mailto: links.
This PR makes several changes to the group SMTP email contents to make it look more like a support inbox message.
* Remove the context posts, they only add clutter to the email and replies
* Display email addresses of staged users instead of odd generated usernames
* Add a "please reply above this line" message to sent emails
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.
Adds a new `smtp_group_id` column to `EmailLog` which is filled in if the mail `from_address` matches a group's `email_username`. This is for easier debugging, so we know which emails have been sent via group SMTP.
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.
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.
When invited by email, users will receive an invite URL which contains
a token. If that token is present when the invite is redeemed, their
account will be automatically activated.
It was used both when inviting from a topic page and when creating
invites with "Send to topic on first login", while it should be used
only in the former case.
We were sending 2 emails for user silencing if a message was provided in the UI. Also always send email for user silence and user suspend with reason regardless of whether message provided.
Feature for `Must Approve Users` setup. When a user is rejected, a staff member can optionally set a reason for audit purposes. In addition, feedback email can be sent to the user.
