Hi,
I recently replaced an older Linux Postfix server with a new OpenBSD
(6.6) and OpenSMTPD 6.6.0.
Most things are working fine, but email sent to my secondary MX server
never get accepted by my OpenSMTPD server -- they always get a 421 error
that looks like this:
smtp failed-command command="DATA" result="421 try again later"
The secondary MX server is running OpenBSD/postfix and reports message
statuses like this:
(host foo.bar.com[192.168.2.2] said: 421 try again later (in reply to
end of DATA command))
Does anyone have some suggestions on what I should be looking for/at to
diagnose/fix this problem?
Thanks,
Jeff
