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.

Thanks for your answer. We find better to count at the Submission Step.
I try to use metric, but don't find yet the good parameters to see submission events :
metric submission_counter { filter = event=smtp_submit_finished fields = mail_from recipients data_size }
Submit some mails and then doveadm stats dump.
result stay null :
doveadm stats dump metric_name field count sum min max avg median stddev %95 submission_counter duration 0 0 0 0 0.00 0 0.000 submission_counter mail_from 0 0 0 0 0.00 0 0.000 submission_counter recipients 0 0 0 0 0.00 0 0.000 submission_counter data_size 0 0 0 0 0.00 0 0.000
