Hi All, We run a postfix STMP relay for customers. One customer is saying that their application is showing lots of timeouts on their end when it is trying to send emails via our STMP relay. We are also seeing the timeout errors in the mail log (shown below).
How do I troubleshoot something like this? \\ Logs on postfix SMTP relay May 19 16:06:50 smtp01 postfix/smtpd[21940]: timeout after END-OF-MESSAGE from unknown[10.84.72.227] May 19 16:10:06 smtp01 postfix/smtpd[21944]: timeout after END-OF-MESSAGE from unknown[10.84.72.227] May 19 16:32:59 smtp01 postfix/smtpd[23036]: timeout after END-OF-MESSAGE from unknown[10.84.72.227] May 19 16:34:06 smtp01 postfix/smtpd[24186]: timeout after END-OF-MESSAGE from unknown[10.84.72.227] May 19 16:53:56 smtp01 postfix/smtpd[24229]: timeout after END-OF-MESSAGE from unknown[10.84.72.227] May 19 17:05:38 smtp01 postfix/smtpd[24190]: timeout after END-OF-MESSAGE from unknown[10.84.72.227] May 19 17:08:02 smtp01 postfix/smtpd[24158]: timeout after END-OF-MESSAGE from unknown[10.84.72.227] Thanks.
