What you encounter when forwarding email from one domain to another can 
vary widely depending on the rules of the receiver.  What is acceptable 
at one ESP can be very different from another ESP.

Google's spam filtering is sophisticated and complex.  Their rules for 
determining what is acceptable for receiving mail to individual accounts 
are probably different from the rules for Google Groups.

If you feel like getting involved with SRS, SPF, DKIM, DMARC, etc. you 
might have better results.
