disable IMAP IDLE

[Ron Vachiyer]

Well after a number of tests, it seems that without IDLE, Blackberries are "smart" and disconnect.  iPhones and mail clients (Outlook, Thunderbird) remain connected.  This is consistent with what they are doing now so they will have to live with it.  Unsure what the real reason behind IDLE-less capability is but I am under direction not to enable it.

Thanks again all,

R.
