[toaster] CHKUSER error

[Dennis Erickson]

Just built new toaster box -

Here is the problem I am encountering when i attempt to send mail.
from smtpd log

CHKUSER rejected sender: from <[EMAIL PROTECTED]:[EMAIL PROTECTED]:> 
remote <MYPC:unknown:123.123.123.123> rcpt <> : invalid sender MX domain

I am able to receive emails on the box no problem.

Thanks
Dennis
