[Xymon] Mail pipelining

[Stephen Carville (xymon list)]

How does XYMon send mail?

I am seeing several of these kinds of messages in /var/log/maillog on 
the mail server (scamail01) but no corresponding errors in 
/var/log/maillog on the xymon (rcaxymon01) server.  This doesn't seem right.

Aug  9 07:21:41 scamail01 postfix/smtpd[32480]: connect from 
rcaxymon01.lereta.net[10.212.2.27]

Aug  9 07:21:41 scamail01 postfix/smtpd[32480]: improper command 
pipelining after EHLO from rcaxymon01.lereta.net[10.212.2.27]

Aug  9 07:21:41 scamail01 postfix/smtpd[32480]: disconnect from 
rcaxymon01.lereta.net[10.212.2.27]

I could turn off reject_unauth_pipelining but I'd prefer not to.

XYMon version: 4.3.29 (built from source)

Platform: CentOS Linux release 7.6.1810

Postfix version: 2.10.1
