Thanks. Can this be configured in a multi-domain environment e.g. via restriction classes in a way where every domain admin can supply his own contact details?If you want multiple Postfix personalities, use multiple Postfix instances: http://www.postfix.org/MULTI_INSTANCE_README.html
That is very interesting. Thanks for the link.
If you have light-weight instances via master.cf smtpd/inet services bound to secondary IPs, you can configure each instance with a different response via "-o" overrides. Otherwise, the feature is correctly designed to append optional contact information for the *system administrator* or a troubleshooting help URL for senders having trouble delivering email via the *system* in question.
Yes, I understand that. But that is not how I experienced the world. Usually, if person X from domain X could not mail to person Z from domain Z for a reject reason given by mail provider M, then X would call Z (I cannot send you mails) and Z would call M (X cannot send us mails). Does this sound reasonable to you?
