What does this PR include?

Short Description

This PR enables saving the quarantine history(queue) for domains that are only relayed and have no local mailboxes. The admin or the domain admin can manage the quarantine and release / delete etc. messages.

This is an implementation of the enhancement request #5325

As a side note, it fixes a typo in a SQL query in pipe.php (no change of funcionality there).

Affected Containers

• rspamd (for metadata export)
• web (for the functions.inc.php) mods.

Did you run tests?

Yes. Using it live.

What did you tested?

Queue comes up. The admin can do all operations. Also a domain admin can do all operation.

What were the final results? (Awaited, got)

It works as expected.

@FreddleSpl0it : I changed the branch from master to staging. Seems fine and I've been using this patch in production for 10 days now. If you need more info or some tweaks, don't hesitate. I wish this could could be merged so that I don't have to patch all my local installs every time I update. Thank you.

PS: The commit states that the quarantine mail is inserted under the "administrator" name. In reality, the destination mailbox is kept in the database, but since we can't authenticate this user against mailcow's db, only the administrator or a user with domain-admin ACL can access it, hence the explanation of the comment.

Maybe a bit late to the party. Wouldn't it be useful if an optional quarantine notification could be sent to the intended receiver ? That way the intended receiver can release or delete mail without requiring administrator intervention.
