tweaked the wrapper script to make it work. It seems like the sa-learn call silently fails:
"/usr/local/bin/sa-learn-pipe.sh" 10L, 350C geschrieben root@vm10:/etc/dovecot/conf.d# cat /tmp/sa-learn-pipe.log starting log 25200-start (--username=johannes@rohr.org --spam) libgcc_s.so.1 must be installed for pthread_cancel to work 25200-end
Does the above error message have anything to do with it? Running the script & sa-learn manually works fine. do virtual users change something how dovecot calls programs, such as chrooting them?
Here [1] is an old thread about that problem.In short: It seems to be a problem in sa-learn that is triggered by the privilege drop that dovecot does when starting.
I have the same problem and I have not found a solution yet.
