Hello,
If you want to use SSL on Debian/Ubuntu, the following configuration
is necessary.
(setq mew-prog-ssl "/usr/bin/stunnel4")
"stunnel" on Debian/Ubuntu is a Perl script which converts stunnel 3's
command line options to stunnel 4's configuration file. The Perl
script does not tell its version (3 or 4) to Mew, so we need to
specify the true body of stunnel.
