Unless I am missing something, the idea of IMAP vs. POP is the ability for IMAP to PUSH the messages to the mail client from the server versus having the device FETCH new messages. A message read or deleted on one device will result in that same message being read or deleted on another device. I have several email accounts that are set up as IMAP on my IP4. In the mail settings, the "Fetch New Data" setting is set to Push, however, when I drill down to the next menu level and select advanced (where each individual mail account has its own settings), the only options are "Fetch" or "Manual". The only exception is MobileMe which is correctly set to Push. None of these other accounts are hosted with Exchange Server. Any thoughts? Thanks in advance.
