Aces, the SQL authentication is really helpful.

Any plans to add options for external filtering such as SpamAssassin, rspamd, etc.? (Assuming it's not there already but I couldn't find anything obviously highlighting that it was.)

Also configurable sub-addressing would be handy - since many websites block '+' in email addresses, I added '-' as a sub-address splitter for my users.

Ah, a thread on the Lobs has pointed me at the "DATA stage" documentation which mentions SpamAssassin and rspamd support. Be nice if it supported the rspamd socket rather than spawning rspamc for each delivery but it'd work in a pinch.
