Yes.

Yes. A long one.

Yes, if they are all getting the same message, just Bcc: them all, and do
one giant send.

Your mail server may cut off Bcc: after 50 users or something though.

You'll have to play with it.

Or, Manuel Lemos' mail class (or other similar solution) will spew things
directly at the mail server port much, much faster, and probably with
fewer limitations than sendmail.

Using PHP for this is not really the Right Thing (tm). Better to have a
real mailing list which was designed for high-volume email.
