Problem with outgoing emails - 5.5.0 smtp;550 "message"
Posted on 2005-04-13
Can anyone help me please. I have Small Bus Server 2003
I have a problem with outgoing emails, evertime an email
is snet external to the company/domain i get a NDR with
the following information
There was a SMTP communication problem with the
recipient's email server. Please contact your system
administrator. <mail.btconnect.com #5.5.0 smtp;550
Recipient Not Authorised [recipient rejected due to no
authorised destination groups]>
I have checked technet and can find NO information
relating to this issue.
I've spoken to my ISP no joy.
