Add an option to use ssmtp instead of sendEmail? Rated 5 out of 5 stars

Wonderful add-on! But sendEmail fails with servers that require authentication...

There is a better tool that works almost identically, and is included with cygwin and all flavors of linux.... 'ssmtp'. Might even be available on macs.

It is invoked exactly like sendEmail (slightly different options).

Would it be possible to add optional support for this command line tool also?
