Pardon me sending this to Suse rather than postfix but that list is really high bandwidth and I'm hoping to catch a postfix expert here. Postfix has a lot of advantages over sendmail and (as far as I am concerned) one killer defect. How do I ask the web of postfix processes what will happen to a given email? The functionality that (insecurely) exists in the SMTP "expn" command. (I always used that through a perl wrapper "expn" anyway) The extensive tracing that sendmail -bt allows. Searching on postfix.org and the net reveals various mumblings about difficulty... Which sounds like a used car salesman trying to explain away a tin windscreen. If you can't see where it's going then what use is it?
