MX Messaging Resources

I have an exchange server at my business.  My agents have been receiving the 4.4.7 message on emails they have been trying to push out.

These are emails sent to single email addresses which are known, trusted and have worked in the past.

Any suggestions would be greatly appreciated.

400's are typically delay messages, without the actual bounce back message it is hard to give more details than that. If you are having a problem sending outbound and/or receiving inbound traffic, think about looking into one of our Email Continuity Solutions (includes use of our trusted Smarthost).

Thank you,
