That sounds wrong. You mean Dovecot backend doesn't notice that proxy disconnected the client and keeps the pop3 process running? That shouldn't happen, unless the pop3 process is doing some long-running work (which it really shouldn't).

No.

You shouldn't. Rather you should just increase the client_limit for the couple of specific services that likely need it to be larger (auth and anvil I guess). http://wiki2.dovecot.org/Services has some explanations.
