I have been looking through /var/log/maillog and the following entries appear for every time that somebody connects to the server:
Apr 4 15:23:26 monster imapd: Failed to create cache file: maildirwatch (cconover) Apr 4 15:23:26 monster imapd: Error: Input/output error Apr 4 15:23:26 monster imapd: Check for proper operation and configuration Apr 4 15:23:26 monster imapd: of the File Access Monitor daemon (famd).
I'm not exactly sure what the courier-famd interface breakdown is. I haven't been noticing any problems with connecting to the server, but I can't imagine that this error is healthy. Any suggestions?
I was getting this too.
You have to make sure that FAM and PORTMAP is running.
