Hey.. this is good info.. Does anyone have a work around 'hack' or what ever to force IMail to try any other avail MX records "regardless" what the 4.x.x/5.x.x response is? How about a future 'check box' or something to allow this. Many mail servers are broke, setup wrong, or what ever that have caused us a lot of grief too - but doesn't cause other email servers any sending problems like hotmail.com, yahoo.com, msn.com, aol.com, etc etc etc....
