Now, there are still the more generic ways, yet probably requiring a bit more guesswork; for example, assuming binary lsof is available on your system:
sudo lsof -n -i :imap,pop3
Handy. Thanks. Of course it only works in the instant I get the message (which isn't always apparent from the client).
On the other hand, I don't remember exactly what happens when that mail_max_userip_connections limit is hit; doesn't Dovecot log some hint that would allow you to track the "culprit"?
Well, not that I could see - that's why I asked on the list :) That's not to say it isn't there, but all I see in the log is: Mar 12 13:47:12 mail dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections): user=simon@example.net, method=PLAIN, rip=127.0.0.1, secured
I suppose this implies it's the webmail client., but even having that open on two different machines shouldn't open 10 connections. Should it?
