I have some ideas for a proper successor which would be much more scaleable, modern, flexible and would be more focused to use existing transports for piggybacking mail. A fully and safely encrypted mail storage as well as a cool interface to invite for encrypted sessions etc. Smtpd and imapd using modern Python modules.

Providers found out it was easier to block private senders instead of developing good filtering mechanisms. I kind of understand this decision, but spammers simply abuse services like Sendgrid or create spam accounts on MS.

So… nothing really changed in regards of spam. We just lose actually *wanted* mails or have to look into the Junk folders more often, all while newsletters get on the priority lane.

That makes me unsure about developing anything in this regard. :(
