Hello,

is there any way to rate limit submission mail (counting per user) when using Dovecot/Submission (no Postfix)?

Using a milter seems impossible. Using Dovecot Events seems "too" global (not per users discrimination). Maybe rate-limiting has to be external and then include in the pass_db query ?

Thank your for any hints.

Hi!

Dovecot submission is not an MTA, it *always* requires something behind. You cannot use milters with it. If your MTA supports XFORWARD/XCLIENT you can use submission_relay_trusted to allow this information to be forwarded to the MTA.
