When I send email from Usermin I get the following error:
Failed to send mail : SMTP command rcpt to: failed : 554 5.7.1 : Relay access denied
The only thing I can think of is I changed the port for Virtualmin and Usermin for security, other than these changes it is a default install of CentOS 6.4 64bit.

Howdy,
Do you get that error sending email to any user? Or does that occur for one user in particular?
That almost sounds like a Postfix configuration issue… what output do you receive when you run “postconf -n”?

That’s for any email address.
Here is the output of postconf -n

Howdy,
Ah, it looks like localhost was removed from the Postfix “mynetworks”.
That would make it so Postfix would reject connections coming from your server.
What you’d want to do is edit /etc/postfix/main.cf, find the “mynetworks” setting, and add this to the end of that line:
127.0.0.0/8
It should look something like:
mynetworks = x.x.x.x, 127.0.0.0/8
After that, restart Postfix, and then see if you’re able to send email from Usermin.
