mailspanner

SMTP client tool.

mailspanner is a commandline client for sending email, in a way that's useful for diagnosing delivery problems. It's intended to be cross-platform, with easy Windows support.

This is not SWAKS, and doesn't intend to replace SWAKS, but should feel similar enough that basic tutorials using a common subset of their functionality should work with either.
