Use the group address form:
To: "Friends of Genghis Prawn" : squiddy(_at_)deepsea(_dot_)net,
sponge-bob(_at_)squaredance(_dot_)com, ... ;
I can tell you from experience that a number of mail servers will
categorically reject that as spam, Gmail being one of them. I think
the only reliable way to do that nowadays is to list your own email address
on the "to" line and use Dcc.
