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

That looks like a permission problem - no x Bits set on the executable and/or directories to it (for the dovecot user)?

For me it seems that everything with the permissions is ok. Others also can execute it?
Other suggestions? Is the config correct?

Thanks that was the reason for the permissions error. Unfortunately the next error comes that isn't explanatory:

Hello
You need to activate vnd.dovecot.pipe extention in dovecots sieve.
Kind regards, Christian Mack

You are right, after configuration now procmail is started and piped the message. Unfortunately some loop happen after starting procmail

Basically I need to achieve the behavior described here: https://www.concordia.ca/ginacody/aits/support/faq/procmail_and_sieve.html Could someone explain in details how to ?
