Exactly.

In that case, do put pinecam.com as the System mail name (so that 
unqualified addresses get "@pinecam.com" appended). After that, create the 
file /etc/exim4/hubbed_hosts with the following contents:

pinecam.com:	aspmx5.googlemail.com:aspmx3.googlemail.com:...

The exact format of this file is detailed in the exim4-config_files man 
page.


Another way which I'm not sure would work is this: Set pinecam.com as the 
system mail name, add it to the relay domains list (but not to the "other 
hostnames" list), and set dc_mailname_in_oh='false' in
/etc/exim4/update-exim4.conf.conf . YMMV with this method though as I 
haven't tested it.

IIRC, I just did a 'host -t txt pinecam.com' at the time and assumed this 
was a fully managed domain (not really familiar with Google's offerings).
