Mailbase is funded by the Joint Information Services Committee of the Higher
Education Funding Councils for England, Scotland, and Wales.  Its services
are very popular in the U.K., and the program itself provides many useful
features, friendly command syntax and user messages, and good efficiency.

Source code is not available.  However, the binaries can be licensed at no
charge; write to mailbase-helpline@mailbase.ac.uk.

To find out the basics of using Mailbase, write "send mailbase user-guide" in
the body of a message to mailbase@mailbase.ac.uk.  Or, take a look through
<http://www.mailbase.ac.uk/> or <gopher://gopher.mailbase.ac.uk/> ... lots of
Mailbase documentation is available there, as well as searching facilities
for Mailbase lists and archives.

Supported platforms: Mailbase is available for SunOS 4.1.1 and 4.1.3 on Sun
4/4m/4c's, and for Solaris 2.3.  For Mailbase to run, your system must also
have two other packages installed: Ingres 6.3 (or later) and Perl.  To save
the Mailbase developers' sanity, you should have some understanding of
Ingres, Unix, and Mailbase itself (as a list owner/member) before you attempt
to install Mailbase.
