Does anybody know what's up with addresses that include the following: ::MRGATE:: We get lots and lots of errors, from lots and lots of different places, whose addresses all include ::MRGATE:: in their from/reply to address. When set to nomail, people at these nodes frequently write to ask why. When I reply (using reply mode), the messages come back to me "no such host". Sometimes, however, those same subscribers send messages that do not include the ::MRGATE:: and then there is no problem with the messages or the replies. At those times, too, our list messages get through OK. Does anyone else have this problem? I am sure that it is THEIR local problem but what can I tell the postmasters (who invariably insist that the problem is at our end)?
