Hello,
I am using the antispam plugin of Dovecot with SpamAssassin and in some cases
when users move back mails from the Spam folder to their INBOX (false positive)
they get the following error message:
[SERVERBUG] failed to send mail
# 2.1.7: /etc/dovecot/dovecot.conf
# OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.8 ext4

What does the Plugin log?

unix_listener quota-warning {

}

}
You seem to use a virtual user configuration, so the antispam plugin
executes spamc as user vmail, correct?
What happens if you run the program manually?
sudo -u vmail /usr/bin/spamc -d my-mx-server.domain.com -u amavis -L ham \
< message
You can also trace the program with a wrapper script. Replace
antispam_pipe_program with /usr/local/bin/spamc-wrapper
==== BEGIN /usr/local/bin/spamc-wrapper
#/bin/bash
( # when and who
date;id;
let i=0
# what
echo /usr/bin/spamc "$@"
# see embedded spaces in arguments
for arg; do
let i=i+1
echo "Arg#$i: '$arg'"
done
# call original program
/usr/bin/spamc "$@"
# log return code / exit code
rc=$?
echo rc=$rc
# Make sure the rc is returned back to caller
exit $rc
# log everything into a file
) >>/tmp/spamc-wrapper.log 2>&1
==== END
If you have lots of simultaneous calls, create one log file per call ->
add .$$ to filename.
