LinuxQuestions.org - [SOLVED] Postfix MailServer Unknown User Error

I have been working on Postfix for a few days now, and I seem to have very little luck. I got it to work internally at one point, but I could receive mail from an external email provider. The current error I'm getting is unknown user.

Here's from telnet, as you can see, it doesn't give me an error message:

Code:

MAIL FROM: <root@My-Domain.org>

250 2.1.0 Ok

RCPT TO: <chaos@My-Domain.org>

250 2.1.5 Ok

data

354 End data with <CR><LF>.<CR><LF>

wat

.

250 2.0.0 Ok: queued as 70CFB161C4D

And here's from my mail.log:

I tried to post all relevant files that would be needed go get assistance. If anything else is required, just ask.

Note: Obv. My-Domain is in place of my /actual/ domain. :3
