Maybe, but in my experience Sendmail and Exchange have one feature in common, there are both keen to drop all your mail down a black hole at the slightest sign of a misconfiguration. I have always thought this was an odd design choice...

N.B. I haven't used Exchange as an admin since before 5.5, so it might have got better in this regard, but I doubt it
