HI guys, I have a question related to outing root@ emails from my server.
I have a centos server with sendmail and I have installed fail2ban and
iptables firewall recently.

The problem is: SNDS by hotmail (microsoft) has listed my server on RED
color claiming sending SPAM from my server, but I completely secure but I
am quite sure you have blocked sending emails from the root account 'on the
server, I tried it. I really not understand what the problem is, does
anyone know who might be happening? How I can finally stop sending emails
from my server root @?

Thanks in advance.


With Kind Regards,

First, look at /var/log/maillog. If you're sending or relaying spam, it
will probably be pretty obvious.

Second, the listing may apply to your entire network, and could be the
result of some other system, or it could be an old listing from a system
which previously used your address. If your system is secure, follow
hotmail's process for de-listing your address.
