From: Martijn de Munnik on 20 Jan 2010 04:56 Hi list, I have a problem with delivering mail to a host and get this error: host mx2.amsterdam.nl[145.222.14.10] said: 421 enepmx02.amsterdam.nl Error: timeout exceeded (in reply to end of DATA command) This error only seems to occur with 'large' mails. Currently I have a mail of ~600KB and ~8MB stuck in the queue. I don't think this is a postfix issue on our site but an issue with the mailserver on the other site. What can cause such issues?

I tried the http://ftp.nluug.nl/mail/postfix/faq.html#timeouts Cisco PIX workaround but that doesn't make any difference?

AFAICS: slow connections, high connection concurrency (leaving little bandwidth per connection), proxy filter or policy service taking too long for checking the mail, etc. However, since the timeout occurs on the remote side, you should contact the administrator of that server about the issue.

Record a tcpdump trace. The way the session fails will indicate the kind of problem (MTU, Window scaling, and so on). http://www.postfix.org/DEBUG_README.html Wietse
