Hmmm...  I am no expert here.  I was planning to use that invocation of
sendmail.  When you talk about passing through other hosts, do you mean
sites on our network, or intermediary sites that are "out there" on the net,
passing mail?

I assumed that sendmail attempted to talk to the addressee's machine, and
when the connection was established, the data passed to the recipient
machine.  Am I confused here?

Also, I have remotely heard of a product called Zmailer.  (someone else
responded with "Ever hear of a product called Zmailer")  I had heard the
name, but know nothing about it.   

I was mainly worried about sendmail bringing our system to its knees if we
queued 1,000 50K messages at once...  How does sendmail handle this?  Does
it go sequentially through an alias :include file, processing messages one
at a time, or can it initiate multiple simultaneous connections?

I definitely will.  Thanks for the help.
