I grew these to 3 minutes for other reasons already. But the mbox
size shouldn't matter here. The OK reply to login command should come
before the mailbox is even opened, and after login those values don't
matter anymore. So what are you doing in your backend servers? :)

Yeah, I saw those changes in CVS. Guess my custom 3.5 minute timeout patches will be obsolete with the next RC.

Basically we have our backend servers doing copying from the mbox to a pop file for message retrieval. With a couple of users having a mbox file > 500MB the timeouts were causing them pain. This and other things were killing my I/O on my backend servers. Fortunately, I'm migrating them (and everybody else) to maildir, so the 3min timeout should be more than ample for them.
:)

Thanks again.
