 On many email systems today, to accept an email, the sender email adress
 must exists. If not this may be the reason fo rejection:
 > RCPT TO:<wordpress at example.com>
 > 550-Response: 550 No Such User Here"
 > 550 Invalid sender <wordpress at example.com>

 If not it should be a warning or recommendation to create it, as just a
 forwarder or full account for storing.
