Hi

If I try to send to two certain domains(maby more will come) the mails end up in the queue, and after a certain amount of resending attempts, I get the error:
"#550 4.4.7 QUEUE.Expired; message expired ##"

When I look in the Queue Viewer, I can see the mails, and they have 2 different errors:
1. "Last Error: 450 4.5.0 No recipient succeeded"
2. "Last Error: 454 5.7.1 DXNS3 xxx.xxx.xxx.xxx: Message refused. Your host name dosen't match with your IP address: mail.me.dk"

I have looked around the web for a solution, but haven't found one, so I hope you can help me.

Thanks in advanced.

Best regards
Lars

If you want your mail delivered properly the Official Host Name of the sending server should match the PTR (reverse DNS) of the sending IP Address, and there should be an "A" record..

The A records of the sending server and the PTR has the same name.

But when I send my mails, I can see one ip address and when I receive I get it from another, because my mx record is hosted with my ISP.

Is that the problem?
