Default Virtual Users and Domains : Mail Loops back to Myself

I followed the Ubuntu 9.04 tutorial two different times now and I always get the Postfix, "Mail.example.com Loops back to myself" error so I was hoping for a little help. I've searched through all threads about this before posting, btw.

I'm wondering if my MySQL transport table has the right values.

Hostname = server1.example.com
MX record points = mail.example.com

I used 'mail.example.com' in all my configs (except where it reflected domain name, and I put in 'example.com')

Should my transport table value be:

source + destination
example.com + server1.example.com (changed but not tested yet)
example.com + mail.example.com (this does not work)


If there's anything else I can check, I'd appreciate some help as I'd really like to get this working.

Output of 'postconf -n'
