At home now, and can answer this a little more in depth.

That line was truncated. Fixed that one.

However, like I said, Google is refusing mails with a source address 
that don't pass various rules they have, which is in violation of RFC 
5321. And the silly think is that the error Google gives refers to RFC 
5321 as a reason why they are refusing.

As the source address should be used when reporting any problems back, I 
cannot really fake it either, without potentially loosing more 
information. I'm going to try and ping people at Google, but I do not 
have very high hopes of this being resolved. So the answer might just be 
that Google is broken, and you should avoid it.

It should have been. Have been all the time I tested. Strange. Are you sure?

Many ISPs won't let you talk SMTP yourself, but you are expected to use 
their mailer as a relay. Might that be what you are seeing?
