Hi,
I have a fedora20 system with dovecot-2.2.13 running various services, including pop3. I'm noticing some users are frequently hamming pop3, and wondered if this was normal, or something I should be investigating?
Aug 8 14:05:20 email dovecot: pop3-login: Login: user=<user1>, method=PLAIN, rip=97.77.115.121, lip=192.168.1.1, mpid=30509, session=<DnRtDCIAUQBhTXN5> Aug 8 14:05:21 email dovecot: pop3(user1): Disconnected: Logged out top=0/0, retr=0/0, del=0/15, size=5693601
So it is immediately followed by a logout, but when there are 50 of them successively in a five minute period, I wondered if it is creating unnecessary overhead on the system?
I suppose this most likely is how they have their email client configured, but wondered if some throttling would be necessary?
Any advice would be most appreciated. Thanks, Alex
