Emails bouncing back

[Matt]

Further, it is possible that if adams email account is on the Missy server, and garys account is on the Missy server, that you could email back and fourth even with your MX pointing to your other host. The root of the problem is that gary needs to actually be a real live inbox on the Missy server. I looked at your cPanel and there is no email address for gary that exists on the Missy server.

I am sending my gary lewis email from a non Missy server in Australia to adam on the missy at your end. Is it that I get a bounce because I am using the alias? Normal emails are OK?
