Hello there I did some more research in the last two days, unfortunately without any result.
First thing, I looked up all the relevant documentation and reviewed our configuration, in particular the directives regarding the quota configuration for POP3. Unless I overlooked something, it looked substantially correct to me. I also verified that the maildirsize file is updated the way I expected, and it is. I then focused on our quota-warning.sh script. I wanted to check if something was going wrong during the execution, so I added two logger commands in it. Now the script logs any execution attempt. Moreover, if it fails to inject a message into the mailbox, it logs the failure. After some debugging, I had it logging into /var/log/debug via syslog (see attachment). The script is in place since hours. Despite the fact that I deliberately triggered a warning condition on an account[*], nothing was logged, so it seems that the quota warning is never issued. And I can't make sense of it, because quota warnings seem to work regualrly via IMAP... Any clues? Pointers? Whatever? Are we missing something? Please don't let the Warnock Dilemma eat me! ;-) Ciao --bronto > r...@mgo2-popimap-v01:/usr/local/dovecot/etc# ../sbin/dovecot -n > # 1.1.7: /usr/local/dovecot_1.1.7/etc/dovecot.conf > Warning: fd limit 1024 is lower than what Dovecot can use under full > load (more than 16384).
