POP3 stop responding
I have upgraded from 8.0.2 to 8.0.3 (CentOS 6.4) one month ago. By a few days, customers complain that pop3 clients do not receive emails, I can telnet 110 port, the daemon is listening but after username and password connection is hanging; I have to exec
very ugly. IMAP is ok, instead, when POP3 is not working.
Can you tell what the logs say at the time when Pop3 stops responding.
mailbox.log was the first thing I investigated to find something related to issue, but there was nothing of abnormal, no timeout, no java error, nothing
Now I will check them, if available
