This feature adds a setting to the control panel to require signing in to
view attachments. This is in addition to the security already provided in
the download URLs. Currently, download URLs are signed for a specific help
desk, and automatically expire after about 24 hours. The exact timing is the
following midnight allowing for at least 12 hours cache time.

Administrators can impose this extra security feature to refuse serving
attachment files if the user is not currently signed in. This could prevent
third-party users from viewing an attachment if they were able to get access
to the download URL before it expired.

If the Return-Path header does not match the From header, emails are significantly more likely to be blocked by spam filters.

This patch forces the return header to match the from address without having to change php.ini and therefore works properly on servers that have multiple apps sending from multiple email addresses for example shared hosting, multiple support emails in one instance etc.

If something like members__staff is considered leaving the Team model,
and the `members` relationship is nullable, and the `staff` relationship is
not, in the context of the compiled SQL statement, the second join should
also be considered nullable (LEFT join), because otherwise inconsistent
results would be returned from the query.

In other words, if a count is considered as an annotation to the Team model
instances, Teams with zero members should still be considered as valid teams
and should be selected with such an annotation. Before this patch, however,
the join between TeamMember and Staff would have been an inner join instead
of a LEFT join, which could skew the database results.
