If you have a Mac that is connected to the network (via AppleTalk - and a
smarter router - which most of them are) or to Ethernet or TokenRing than
you can use a HyperCard stack to compose a SMTP message and post it to
ANY SMTP server that will accept stuff from it on the network (including,
obviously, the one you are trying to send to.)  There is a package called
HyperTCP (or somesuch) which is free and came with the NetNews reader,
among others, that will let you access all of MacTCP's (which is, alas,
not free, as of system 7.1 :-() functions!  I have written many TCPIP
clients using this package and it's VERY simple.  As for HyperCard as
a MAIL front end - nothing could be simpler.  It could handle nicknames,
check parameters, verify syntax, etc..  If you provided LISTSERV with
a TELNET (TCPIP) style interface for LDBASE then you could make a HyperCard
stack to directly access it.  Anyway, with some effort (are you asking me
to do it?) it can be done.  - Yossie
