553 sorry, that domain isn’t in my list of allowed rcpthosts (#5.7.1)

What does a “Reason: 553 sorry, that domain isn’t in my list of allowed rcpthosts (#5.7.1)” error mean when an email message bounces back to the sender?

This probably means that the server of the recipient is refusing to accept the message from the mail server for your account.

The Above error will be bounced back to a sender if the email address the sender is trying to send to is not fully activated: “Reason: 553 sorry, that domain isn’t in my list of allowed rcpthosts (#5.7.1)” This usually occurs when:

1. If your ISP provider blocking any other out going servers.

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. Chances are that your out going will acually be faster that way anyway.

2. The domain name contained in the email address (being sent to) has not fully propagated yet. Domain propagation is the process where Internet Service Providers (ISPs) around the world automatically update their records (DNS tables) to reflect the new domain or to reflect a change in the hosting provider for the domain name. Once the changes have been made, the domain’s website and email services will be activated. Please note that full domain propagation can take between 24-72 hours. To verify when your domain was last updated, we suggest that you conduct a whois on your domain. A popular whois tool is located here: http://www.allwhois.com.

3. Your POP mail client (ie. Outlook) is not configured properly. We suggest the following:

Solution A: Please ensure that the SMTP port number is set to 25 and that the option “My outgoing server(SMTP) requires authentication” is selected. But if the problem persists, then deselect “My outgoing server(SMTP) requires authentication”. If this still does not resolve the problem, proceed to Solution B.

Solution B: For SMTP port number setting, use port 587 instead and “de-select” the option “My outgoing server requires authentication”. But if the problem persists (this will be the case for a minority of e-mail users), then “select” the option “My outgoing server(SMTP) requires authentication” as well.

IMPORTANT: Also ensure you are using your full email address as your username. There were recent security changes made over the last couple of weeks to ensure no unauthorized email access is used. Below are instructions on how to configure SMTP authentication across various EMAIL Clients.
