Bug#255955: copyright for mmail 2.3

[Thomas Bushnell BSG <tb@becket.net>]

I am working on the Debian package for mmail, and I noticed that its
copying permissions are very unclear.  You distribute a copy of the
GPL with the program, but you never actually say that the program may
be distributed under its terms.  All I can find is this:

#
# (c) 1998-2004 Jan-Henrik Haukeland, <hauk@tildeslash.com>

I would like to keep this package in Debian, but we cannot distribute
it without proper permissions.  

If you look at the GNU GPL, you will see some instructions for the
normal way to apply the GPL to a program.  Basically, we need some
kind of licensing statement attached to the copyright; merely
distributing a copy of the GPL along with the program is not
sufficient to legally grant permission.
