Hi everybody,
trying to get the Dovecot antispam_plugin to work and I must be doing
something wrong, because as soon as it is enabled with a certain
backend, imap logins do not work anymore (the session is immediately
closed after a successful login). Interestingly, pipe and spool2dir are
working (that is, the session won't be closed), dspam-exec and
crm114-exec are not. If this happens, mail_debug output is as follows:
imap-login: Login: user=<dof>, method=PLAIN, rip=127.0.0.1,
lip=127.0.0.1, mpid=10420, secured
imap: Debug: Loading modules from directory: /usr/lib/dovecot/modules

Without the plugin I get:
imap-login: Login: user=<dof>, method=PLAIN, rip=127.0.0.1,
lip=127.0.0.1, mpid=10469, secured
imap: Debug: Loading modules from directory: /usr/lib/dovecot/modules

imap(dof): Debug: Namespace : Using permissions from
/var/spool/dovecot/mail/dof: mode=0755 gid=-1
Hopefully this is just a configuration problem. I tried the plugin in
the Ubuntu repository (I'm using LTS 12.04) and even checked out the
source from git and compiled it myself, but to no avail.
Thanks a lot in advance and best regards,
Florian
