Today in "Google broke email" Dear Lazyweb, if I have to self-host IMAP for my non-nerd staff, how do I deal with filtering? I am *begging* you to read the whole post before replying: Currently, my staff emails arrive at their @dnalounge.com address and Postfix forwards to their Gmail addresses with all of the usual DMARC/DKIM/ARC/SPF flavoring.

@jwz@mastodon.social I had some success a few years back with Roundcube webmail, with dovecot's managesieve to, uh, manage the sieve. That said there was always a "why can't we just use exchange" and I eventually left. Still have the config if you want.

@jwz@mastodon.social I appreciate your problem. The only thing I can possibly think of might be IMAP sieve with some magic folders for white- and blacklisting. Imapsieve runs sievescrips (comfigured in dovecot, not user-managable) on the mailserver in response to actions like moving an email. So your people could have magic folders in which they copy/move the email to add/remove the address to the lists, the sieve script should be able to move the email back to where it came from after changing the lists.
