Not sure, I personally think that moving them silently makes errors harder to diagnose. I'll add an option since then you can set this option (antispam_missing_signature = [error|move]) to move after you've tested and verified that it works just fine. johannes signature.asc Description: This is a digitally signed message part

The problem still remains and the outlines are: - antispam plugin is compiled, configured for dspam and debug is switched on. - plugin starts with dovecot and throws debug info to /var/log/messages (debug logging activated via syslog) - as soon as I move a message into the spam folder it gives an error message saying antispam signature not found I checked that the given location for the dspam executable is correct, that the user executing it (dovecot?) is actually able to execute dspam and that dspam trusts this user.

Personally, I don't set anything but the spam folder, trash folder names and
the
args to pass to the dspam executable. It works here flawlessly.
plugins {
antispam_trash = trash;Trash;Deleted Items
antispam_spam = SPAM;Spam;Junk
antispam_dspam_args = --client;--deliver=;--user;%u

Re: [Dovecot] antispam plugin claims antispam signature not found

I am using dspam in a different setup; I run it under amavis so the user
is always the user amavis. I don't run a daemon so --client makes no
sense. What does deliver= do? Is that the same as
deliver=innocent,spam ?
I think it must be related to permissions in some way but I do not see
how. I would like to debug it further but am no C programmer. I cannot
see why it is not able to extract the signature.

Yes, you are correct about not needing '--client' in your case. '--deliver='
means
deliver nothing, just process it. Since I don't use quarantine on my setup, and
the message is existent already in IMAP, there is no need to deliver anything.
