[outages] Blackberry Email Troubles?

Agreed. Unfortunately one of the largest providers of hosted mail, NetSol, still won't support this. If any NetSol engineers are reading: your customers would appreciate this functionality.

BIS supports the IMAP "IDLE" command where the connection stays open and the
IMAP server notifies the client when a new message arrives. So presuming
that your mail server supports it (and most do now days), it's basically
true "push" email without the need to do any form of polling.

If your server doesn't support IDLE, then it uses polling as you've
described.
