I see from watching and from a message in this mailing list that idle imapd daemons will die after 30 minutes.

Um, practically speaking, what does that mean for the client? My experience/bias with http makes me want to lower this 30 minutes to something more like two minutes. If I could do this, what would the user experience?

Bad things. RFC2060:

5.4. Autologout Timer

If a server has an inactivity autologout timer, that timer MUST be of at least 30 minutes' duration. The receipt of ANY command from the client during that interval SHOULD suffice to reset the autologout timer.

IMAP is a remote message store which you browse interactively - and many mails take longer to read than 2 minutes. The burden on the server of maintaining an inactive process is minimal; the burden of doing additional authentications and re-scanning mailboxes is not.

Cheers,

Brian.
