Hello list! We are being blacklisted every few days from verizon. This is
less important right now as I need to find out if/who is sending spam from
the email server or if the server is an open relay. I am less inclined to
think postfix (which is what we use) is an open relay. More inclined to
think someone has gotten an account is sending spam out using the server.
What is the best way to find out who/if an account is sending spam from the
server?
I am trying to gain access to the mail server as we speak but the password I
have been given is not working so I can not provide you with the version of
postfix or any logs at this moment.
