There are 3 possible reasons your email is being rejected when you send to your domain.
- Your domain name has not yet fully propagated through the web and some routers can not find your site on the new server, thus sending back a failure. Please allow up to 72 hours for your domain name changes to propagate through the web after the DNS updates have been completed.
- You do not have an email alias configured for that name. You can set up a catchall to have all email to non-existent users be forwarded to an existing email account (NOTE: enabling the catchall will result in a lot of extra spam). If you do not want the catchall email address active simply assure the aliases you are sending to are in the user section as name only and not name@YourDomain.com.
- Email was not enabled on your account due to a request or an error. Contact our support staff regarding this issue.
