And that's the most efficient way to send a message to a lot of people.... the SMTP RCPT TO: headers list all recipients, regardless of "to:", "cc" or "bcc". That's because the to, cc and bcc headers are part of the rfc822 headers and are not even looked at by smtp servers along the way. (In fact, I wrote some code to send messages via smtp, and never put a bcc header in the rfc822-header part... my thinking is if it's "blind" then don't rely on the client to keep it hidden. :-) So "bcc" recipients always just go into the "rcpt to:" smtp headers
