[MlMt] Redirect Auth Error

[Chad Albert]

Good day,

I am getting an error trying to redirect. I don’t get errors sending 
or receiving.
Unexpected return code 551 (expected 250):
“5.7.1 Not authorised to send from this mailfrom address”.

Any ideas? The SMTP section in activit viewer shows an %40 in place of 
@. Might tat be it??
