Emails bouncing back

[Matt]

So if I am understanding you correctly, you have a forwarder setup from andy, to gary, and you are sending to andy from your gary address in AU?

[Gary Lewis]

Sorry for the confusion. Clarification.

I am sending an email from my alias address which is hosted in Australia (non glowhost) to adam which is an account I have set up on glowhost using my reseller account. When I send from me to adam, it bounces back.

Is this because Missy doesn't like forwarded (alias) emails? But ordinarily will handle emails to and from adam.
