Given that nobody shared any insight here, I decided to stand-up a completely new VM with Ubuntu 12.04 LTS and see if the same error occurs. While the error is different this time around, I am still unable to get any variant of the dovecot-antispam plug-in working. When I attempt to use the current packages from Ubuntu 12.04.1 LTS, and I use the above configuration, my syslog fills-up with the following: dovecot: imap-login: Login: user=<u...@example.com>, method=PLAIN, rip=10.0.1.57, lip=10.0.1.8, mpid=2879, TLS dovecot: master: Error: service(imap): child 2879 returned error 3 Surprisingly, I can find only two other mentions of "error 3" anywhere on the Internet. Those mentions were from another user to this mailing list: http://www.dovecot.org/list/dovecot/2012-August/067787.html http://www.dovecot.org/list/dovecot/2012-August/067814.html The lack of "error 3" ubiquity leads me to believe that I must be doing something stupid. There's no question that this behavior is related to the antispam-plugin, because when I commented-out the relevant lines in Dovecot's configuration file, the error does not occur. I have followed the instructions at http://wiki2.dovecot.org/Plugins/Antispam to the letter, and this is the result. The only instance in which I diverged from the Wiki article is that I used the Ubuntu-provided dovecot-antispam package (instead of compiling the plug-in from source). I am trying to use the "mailtrain" back-end, per the above-cited Wiki article, to call SpamAssassin's "sa-learn" utility for real-time learning. I am not using the SpamAssassin daemon (spamd). I'm about to throw in the towel on this plug-in, so any help would be greatly appreciated. Thank you, -Ben
