Cannot Receive external mail - Postfix, Courier, MySQL And SquirrelMail (Debian Lenny

[x-built-Stan]

I followed the virtual domain setup on the forge @ http://www.howtoforge.com/virtual-us...l-debian-lenny

When I send email from the local server via mailx it works fine and get to the virual user. I can log into SquirrelMail and see the message. However, when I send mail from any outside server it gets kicked with a 550 and the following message:

Generating server: hqpexedg02.admin.cci.edu

johndoe@mydomain.com
p3pismtp01-015.prod.phx3.secureserver.net #550 #5.1.0 Address rejected johndoe@mydomain.com ##

I have gone back throught eh tutorial several times and each of the checks, everything looks good. Can anyone assist?

Please check if the MX record of your domain points to the correct server. You can check that with

dig mx yourdomain.com

Man - you nailed it on the head.

My ever so helpful DNS provider routed my MX record to their mail server. Changed it mine and everything is great.

I should have seen it - Thanks again.
