Would like to get an option to be able to change the timout for connecting to an IMAP server to download emails.

Had a problem where the Imap server was allowing a TCP connection, but then it would hang once connected (faulty Exchange server).
However this meant the when running the redmine:email:receive_imap rake task, it just stayed running for a long time (not sure how long before it was timing out through normal socket timeouts).

The ability to set a timeout - would allow it to be tuned to ensure that processes didn't just hang forever.
