bstephenmitchell on "[Plugin: WP Mail SMTP] Will only send from one email address"

From within woocommerce, it will only send from one email address - the one I originally used to set the whole thing up.

Even now with this plugin, I changed it, and emails don't send. Put it back to the original email, and emails go.

Please help.
