I just put all the addresses  into a comma-separated list (with a loop 
or implode() ), then put this in the Bcc header, using an "archive" or 
administrative address for the main recipient (and Reply-To).  Using Bcc 
means no one will see anyone else's address ... and I can send the 
message with one call to mail() ...  I've found this to be much simpler, 
and it probably saves a few CPU cycles, to boot.
