Not that I have noticed, not for many years. I suppose IP reputation has a lot to do with it, and also that any site sending marketing mail should sign up for feedback loops with large receivers such as Yahoo. There are more unknown variables here that inhibit useful comment. One thing I'd like to point out, however, is that the emails aren't "from Postfix", and that the blocking has little or nothing to do with the choice of MTA. Yes, some of the workarounds for poor or nonexistent IP reputation include various transport(5) hacks, but ultimately to address the problem, the answer lies outside of Postfix. I'd recommend: - strict list hygiene - sign up at dnswl.org - if money depends on deliveries, spend some on a good ESP -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
