Sources or hosts?
I don’t expect a given host to answer on port 25 just because it
sends, but the domain in the return path should be accepting mail
properly. If they can’t be bothered to receive their DSNs then they
are not likely a good-faith sender.
DSN is not sent, its generated by there own closed port 25 still, so DSN
works without port 25 listners
maybe accept and bounce should really be stopped ?
