Without recompiling postfix, is there a way to get the PTR hostname
warning to come after the connect message in the logs?
Adding to the reply from Wietse, which I have to agree with:
On my Ubuntu 18 mail server, everything that postfix sends to syslog
includes the PID of the process. An example:
May 29 10:57:17 bilbo postfix/smtpd[8707]: disconnect from
unknown[186.250.196.123] ehlo=1 auth=0/1 commands=1/2
The PID here is 8707. If you find a connect message and want to see if
there is something that got logged for that connection beforehand, just
search backwards for the PID. At the following link you can see all the
log messages from pid 8707 in the vicinity of that one I pasted above.
It includes several warnings. I have now run newaliases and postmap to
get rid of two of those warnings. :) This paste will expire one month
from today.

The improper pipelining warning is from xymon probing smtps. That one
is annoying, and I haven't yet attempted to create a fix for it and
submit it to the xymon project. Have to try and remember what I know of
C programming. :)
Thanks,
