Hello,
I'm trying to achieve the following scenario with dovecot + sieve +
procmail.
Dovecot is set as LDA in postfix (if this makes any difference)
I need to set sieve that after it has executed all it's scripts
(including before, ~/.sieve etc) and if keep is in still in effect to
call procmail to also execute the custom user filters and then return
(if it is not forwarded elsewhere or some) to dovecot for normal delivery.
If you ask this I need this for backward compatibility. I now use
procmail for local delivery,spam/virus filtering, and users have set a
lot of custom filters/redirects.
mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME
I want to migrate to dovecot as lda and sieve for filtering but to
keep procmail working for a while.
I have tried to follow (partially) this guide
https://www.enricozini.org/blog/2022/debian/migrating-from-procmail-to-sieve/
but procmail fails to execute
