Motorola Atrix 4G :: Data Push For GoDaddy IMAP Accounts Not Working?

can't get the Data push feature to work on my two GoDaddy IMAP email accounts. When I first turn on Data push, it appears not to change mode, and no test messages get transmitted until I force it to fetch. After power cycling, the accounts no longer receive any mail at all. The green "throbber" circle, at the upper left, next to the account name, never stops spinning, and no mail ever shows up. I do not receive any more mail until I turn of Data push and reboot the phone. K9 works perfectly, on the same two accounts, and receives new messages immediately. I would really like to use the native client so that I can take advantage of the Motoblur messaging widget, but timely arrival of mail messages takes precedence for me.
