New Mac OS X Server setup, when i send mail to gmail it goes straight to Spam. Why is that?

New Mac OS X Server setup, when i send mail to gmail it goes straight to Spam. Why is that?

My setup:
DNS - done (A records PTR are ok)

Mail Setup - done
Webmail - done

Also there seems to be a naming problem. They all come from me@server.domain.com instead of me@domain.com. I must be missing an alias somewhere.

I've read an entire book on setting this up so don't throw stones :)
The GUI is masking a lot of this up for me, so explanations via GUI are appreciated.

The headers look like this:
