Problem to send a mail with Qmail

Hi,

I try to send a mail with the mail function in PHP.
When the command is executed, the mail is redirected in the queue with this message in the "maillog" :

Sep 28 21:12:51 machin qmail: 1190974371.270667 delivery 22: deferral: 202.87.159.6_does_not_like_recipient./Remote_host_said:_451_Temporary_local_problem_-_please_try_later/Giving_up_on_202.87.159.6./

Have you an idea to solve my problem.

Thanks a lot.

This sounds like the same problem I was having... I kept looking everywhere on my server and finally... I noticed that the firewall settings in Plesk where not allowing my mail to go out. By default the setting was not setup for outgoing communication so I had to create a custom firewall setting. After the first test, all my mail was being distributed.

hope this help you.
 
Greetings:

Good point.

I would also add to make sure all servers allow UDP 53, name servers allow TCP/UDP 53.

Please also make sure your mail server IP is set up with a reverse DNS through your data center.

Thank you.
