Hello List,
I am getting a lot of repeated 421 try again later errors from various
lists that I am a member of. There is one in particular that is coming
from outbound.foodtecsolutions.com
<http://outbound.foodtecsolutions.com>. Here is an excerpt from my
/var/log/maillog. I am running OpenBSD 6.6-current #344.

Below is my smtpd.conf file:

match for any action "outbound"
I am out of ideas with which to troubleshoot. I am already running
smtpd with -v switch for more verbosity.
Thanks,
