SSMTP Issues

So I sent an e-mail from unMenu fine and there didn't seem to be any errors on this end but when I logged into google this was the mailer daemon I got from the goog.

Delivery to the following recipient failed permanently:

    [email protected],

Technical details of permanent failure:

Probe failed: Illegal envelope To: address (invalid domain name): [email protected],
