smail vs. sendmail

[Bill Wisner]

Smail3.1 does speak SMTP. It also includes support for SMTP over UUCP.
The smail binary gets linked to several different filenames, one of which
is rsmtp. rsmtp, like rmail, is intended as the receiving end of UUCP
mail, but rsmtp expects to find things in SMTP format. It is also fairly
simple to kludge up Smail3.1 to do batched SMTP, if you really care to
bother.
