It's even in the RFC. Yes, I see that. I think this part of the spec was most likely counter-productive. There seems to have been an arms race with clients trying to keep the connections alive and the servers or server managers trying to close them before the clients get around to doing that. In the end, several ISP's now close IMAP connections within minutes. Even timeouts as short as 30 seconds have been reported. Perhaps this game has now been lost irretrievably. Note that if the client keeps the session alive, then it should take responsibility to eventually close the connection. Cheers, Uday
