This is a postfix-1.1.11 running on RedHat 9.0 (not my fault:) - I usually have a mail queue of about 500 messages. Last week (and after a colleague upgraded and left for Australia) the queue started growing exponentially. Today it's about a 2000 messages sitting there (my q-size is calculated from 'active' and 'deferred').
I have tried pflogsumm-1.0.4.pl and noticed alot of 'Connection timed out' messages:
/var/log/maillog:14153
/var/log/maillog.1:31009
/var/log/maillog.2:31069
/var/log/maillog.3:30377
/var/log/maillog.4:20078
/var/log/maillog.5:18484
/var/log/maillog.6:13999
/var/log/maillog.7:15149
I have found something about concurrent connections which might correct this - any ideas?
That's all I know so far. Any help highly appreciated.
