Email failure to a specific domain (broken pipe)

**elleryjh** · 03-15-2006 10:03 AM

I am getting a broken pipe on connecting to a specific host. The destination host is another server, not running cPanel. I can traceroute to the mail server normally, and perform a simple telnet over port 25 to test the SMTP. Can anyone give some insight to what is going wrong here?

log entries from /var/log/exim_mainlog:
