Can you call (message-make-fqdn)  (hit `C-x C-e' after the closing
parenthesis)?  Also call (message-user-mail-address) and let us know
what they say.  Finally, what's the value of user-mail-address (use 
`C-h v' to find out)?

If your user-mail-address is set properly you should not get that
message ID.  In your particular case you should get
<random-id@googlemail.com>.

Generally speaking, you can make any message ID you like, it's just good
netiquette not to unless you don't have your own IP in a static domain.
I don't know if there's a relevant RFC, but at least this draft infers
you can generate it with the domain of your e-mail address:

supported by some discussions:

I wouldn't worry about it.  The chance that Gnus' algorithm will
conflict with Google's algorithm is negligible.  Of course, avoiding
this possibility is your choice.
