Please note that full domain propagation can take between 24-72 hours. If this still does not resolve the problem, proceed to Solution B.
To verify when your domain was last updated, we suggest that you conduct a whois on your domain. Solution B: For SMTP port number setting, use port 587 instead and “de-select” the option “My outgoing server requires authentication”.
The message content or media status codes report failures involving the content of the message.
These codes report failures due to translation, transcoding, or otherwise unsupported message media.
Security and policy status issues are assumed to be under the control of either or both the sender and recipient.
Both the sender and recipient must permit the exchange of messages and arrange the exchange of necessary keys and certificates for cryptographic operations.

The domain name contained in the email address (being sent to) has not fully propagated yet.
The networking or routing codes report status about the delivery system itself.

For Internet mail names, this means the address portion to the right of the "@" is invalid for mail. The mailbox address as specified matches one or more recipients on the destination system.
Solution: Put your ISP out going server name in the outgoing box of your e-mail set up and let them handle all the outgoing.
It does not affect the rest of your mail and your recipients never know the differance.
Message content or media issues are under the control of both the sender and the receiver, both of which must support a common set of supported content-types.
