I choose OpenSMTPD because ... it's just the best SMTP server I ever seen :) So, trouble 1: I have a message pending in queue with error return: BANNER rejected: 554-mx.example.org Your access to this mail system has been rejected due to the sending MTA's poor reputation. If you believe that this failure is in error please contact the intended recipient via alternate means. I can't do anything for the moment for this trouble, so I remove the message from queue. When I show queue, message is removed. But I look in logs, and I see smtpd still try to connect to the relay. So I restart OpenSMTPD to apply change and the message come back in the queue !!! I don't understand why. And, trouble 2: A user sent a message to domain @club-internet.fr (don't laugh, It's not me :) ), and the message fail because OpenSMTPD can't resolve this domain (MX fail error). But on the system, I can resolv name, mx and @IP of the mx. Why my system can resolv domain and mx but not OpenSMTPD ? Thanks Antonio C -- Ce message a ete verifie par MailScanner pour des virus ou des polluriels et rien de suspect n'à ete trouve.
