Hello everyone. On my server installed on debian wheezy perfect server following the manual. The server is installed, postfix, deovecot, apache 2. I just detect that some of my emails are not delivered siende. Apparently the problem is the connection time. The mistake that for me is the following: B22562A817EF Mon January 12 6183 12:00:31 concello@tra*****.es (.. Conversation with Mail.X ****.es [85.36. *. *] Timed out while sending end of data - message be sent no later than May eleven) cau@x*****.es Someone tell me what could be causing the problem and how it could solve ?? thank you very much
Check if your server is on a blacklist, e.g. at mxtoolbox.com and check if your server has a high load, e.g. by running the command "top" on the shell.
I have checked the blacklists and neither ip or domains found in any blacklist. Furthermore the server load is good. so that is not the reason for the time out for some post only.
The timeout could also be a problem on the remote-site. Can you telnet to the remote-server on port 25?
Hello everyone. After reviewing and testing, it seems that the reason that the emails fail to be delivered is by the size of the headers. How could adjust the size of the head of the mails? thank you very much
