My postfix server will not allow me to send mail except if I am on the server it self.

I am trying to send mail from a local network windows machine. I do not know if it matters that my linux server is in a dmz zone with a static ip, and I am trying to send from the local private network. The error I now receive is..

<brandon.lee.caudle@gmail.com> receipant address rejected. Relay access denied.

Any help is appreciated.

Have you used auth'd yourself? Have you tried a manual connection to test and see if everything is working?

Will show you how to test your smtp auth and generate the necessary information at command line.

When posting log messages, it's best to cut and paste the entire message, preferably in a [code] block.

The mynetworks parameter contains networks that postfix will relay mail from. Yours looks strange. Fixing it is the fastest way of solving your problem. See here for basic postfix configuration.

As rweaver mentions, you can also use smtp auth, but that might be overkill in your case, or something you may want to read about in the future as you become more familiar with smtp and postfix.

Quick caveat for the previous posters information, he is absolutely correct putting your ip "range" in mynetworks is the fastest fix, but it's only an acceptable fix if you have a static or nearly static address. If you have to broadly include a class B or A to keep your ip address in the mynetworks list you're likely to have spam relayed off your server.

As per OP's statement, the network in question is presumably RFC-1918:

*cough* missed that line in original message
