deliverability

I have set up an alias in /etc/mail/aliases like this:

user: [email protected]

This relay DOES work when I telnet to example.com 25 and send mail to [email protected] (where example.com is my domain); it indeed turns up in [email protected] inbox.

Also mail sent from my server at example.com is generally deliverable to this same email address, [email protected].

HOWEVER, the relay DOES NOT work when I send mail from [email protected] to [email protected], expecting it to be relayed back to [email protected].

The mail.log shows it being received and sent just fine, so I guess it is being blocked by gmail for some reason. Why though? As I said, gmail generally does except mail from this server.
