My linux box isn't able to send mail to any verizon.net email account. The best i can figure out is that it doesn't like the return address.

The return address my machine uses is <user>@tourian.foresthills.sad12.k12.me.us

How do i go about changing the setup so i can mask the return address with some other email?

It's doing a reverse dns check to see whether your mail address owns the ip number...

Do dig -x yr.ip.number and see if your dns reverse zone is setup correctly...

I get this:

Is it set up correctly? I don't need to receive email back to the machine. Its a message board and a cgi script on my website that are trying to send emails.

oh, and it sends emails beautifully to any of my other email addresses.

It gives me this error: Error 450: Sender Domain Not Compliant with RFC 822 / Verify the Return Address

Is there ANY way i can change what my return address is?
