The main differences are that the versions I have here are newer, I'm running Debian sid, the server is on Ubuntu Precise, and second, the server is handling virtual users, locally I have only real Unix users. Also, dovecot doesn't complain about configuration errors regard --username=%u.

Hi List, does the antispam plugin any way of actually seeing how it is calling the pipe program and how it is failing? I can't reproduce the failure when I call sa-learn manually. Can someone tell me, with which UID the call happens, is it the UID the current dovecot process is running under (which would be vmail, as it is a virtual user setup) Cheers, Johannes Am 12.04.2016 um 23:09 schrieb Johannes Rohr:> Hi Tom, > > Am 12.04.2016 um 22:26 schrieb Tom Hendrikx: >> On 12-04-16 20:14, Johannes Rohr wrote: >>> Hi, my setup is a dovecot 2.0.19 IMAP server on Ubuntu Precise >>> with >>> the antispam plugin in version 2.0+20120225-2 and spamassassin at >>> version 3.2.2 >>> >>> I have been trying and failed to get the pipe backend of the antispam >>> plugin to work.

The wrapper script is not actually useful for production, but it is for debugging. That is why I asked for its logging, and any differences between manual run and a dovecot run.
