You might run an MTA on the server. Running it on the clients is
probably overkill.

BTW I think I said earlier that I accepted the need for sendmail because
some other stuff assumes it exists. I should have said that the other
stuff assumes the sendmail *program* is available, but it doesn't assume
there is a sendmail *daemon* actually running. AFAIK you could just turn
it off. It's not consuming significant resources so it's not a big deal,
but from a security standpoint it's good practice not to run stuff you
don't need.
