Re: ssl on ssmtp

[Robert R Schneck-McConnell <schneck at math dot berkeley dot edu>]

Two general points:
(1) Don't e-mail cygwin package maintainers directly; use the mailing
list.  Some maintainers don't like private e-mail, and it helps to
have things in the archive.
(2) Read the package README files in /usr/share/doc/Cygwin/.

The upstream source is the Debian package at
http://packages.debian.org/testing/mail/ssmtp
(Hmm; looks like it's time for an upgrade)

It does not have --enable-ssl on by default; this question is answered
in /usr/share/doc/Cygwin/ssmtp*README

Perhaps ssmtp should --enable-ssl by default?  Opinions?

I don't know what the right fix would be.

You have to set the port number yourself.  I believe you want 465?
So in /etc/ssmtp/ssmtp.conf, you would have a line like

mailhub=mail.your.domain:465

Best,
