Hello Admins, I am seeing a lot of this in my mail log lately and do not see the message bounced, blocked, or passed spammy results.
How do I determine if these are coming in under the rules "radar"
SMTP: email@example.com> -
<firstname.lastname@example.org>,BODY=7BIT 250 2.0.0 Ok,
from MTA([127.0.0.1]:10025): 250 2.0.0 Ok:queued as
for those allowed to forward to my domain or user accounts?
In addition, what are the best practices for stopping intruders from FWD via SMTP through my domain mail server?
Right now only users should be able to connect and route mail through my mail server. I do not want to be contributing to the Spam already out there.
