Great!  I get to go cut and paste again because the 
message was an attachment instead of part of the body.
It would also be nice if you would use the SUBJECT: field
in your messages.

Why not just say ...
newsletters: majordomo,

Do you mean duplicate email-addresses?  True, but how can you tell the 
difference between dliston@netscape.com, danliston@netscape.net, and 
dan_liston@hotmail.com?  Now, if all three addresses are subscribed to
your list, and the dliston@netscape.com address has an auto-forward set
up to go to both of the other addresses, it would look like 2 out of the
three addresses got duplicates.

You should consider using bulk_mailer, or a newer version of sendmail that
lets you utilize multiple queues.  Until that time, I would recommend 
stretching out your queue runs.  If sendmail is started with a command like
sendmail -bd -q30m 
I would try setting it to
sendmail -bd -q2h

To increase your delivery performance, you should sort your lists by domain
remove any "bad" addresses as soon as possible, and strip comments out of 
the list.
