We maintain a private relay server to send ebills for a customer.
Please send more details on your setup: OS, postfix version, "postconf
-nf" output, etc. Give more details
During peak sending hours, we miss about 5-10% of incoming messages
but outgoing messages are available.
So the emails arrive succesfully, but the rsyslog messages are lost?
In that case, look at your logging infrastructure. systemd based
systems are notorious for dropping syslog messages under load.
We capture subject line in incoming message to track ebills. When
incoming messages are missing, we are in trouble.
So write the log files to a local filesystem. Or push all the
incoming emails through a milter which logs the ebill info into a
seperate system. Or better yet, just scan the incoming maildir (are
you using maildir?) once a minute for new mail files and then scan
those mails for the information you need.
Mail log written by rsyslog.
Need help either
1. to fix the issue
2. Or write Subject in outgoing message
You need to re-explain your entire process here, since nothing you've
given us really shows the problem details.
Assume you're explaining it all to someone in accounting, and give
that kind of detail. *grin*
