This is absolutely nuts. We have Modernbill installed on our Cpanel server. We send out billing notices to our clients daily, monthly to pay thier bills. I happen to send out an invoice from Moderbill to one of my contract customers that i do work for. Our email goes out as email@example.com. Guess what? While watching his sendmail i see this crap arriving to his email box on his server.
Apr 16 22:55:37 my sendmail: h3H2tbt15038: from=<firstname.lastname@example.org>, size=1542, class=0, nrcpts=1, msgid=<E195zv7email@example.com>, proto=ESMTP, relay=root@localhost
Look at our FROM!!! Its from firstname.lastname@example.org? How is this possible?????
And howabout this part?
email@example.com>, proto=ESMTP, daemon=MTA, relay=mydomain.com [64.xxx.xx.xxx] (may be forged)
MAYBE FORGED? How is this possbile? Please explain this to me. So all email sent from our billing system has been sent as firstname.lastname@example.org even though our address is email@example.com? This is just ridiculous! Hows that for a professional appearance? I am pissed off as hell.
I never thought in a million years that email is arriving at its destination as nobody???? I thought it was our real address.
