Is it possible to change the message “smtp;554 Mail from user@domain.xx rejected for policy reasons” ?
If I configure to Domino to “Verify connecting hostname in DNS”, the server returns non-delivery message to the smtp sender without any explanation why the message was rejected. Some smtp senders are not spammers and do not have mailserver registered in DNS, I would like them to know that they should register mail server in DNS properly.
Is it possible to change message “rejected for policy reasons” with another message, that explains the requirements for smtp mail?
