Check Your MX Record Check Your MX Record Email Protection Administrator Guide Be aware that because of the nature of the Internet, it may take several days for your MX record redirect to propagate to all the email servers that may be sending email to your email server. During that time, your email server may still receive email directly from those email servers until they are updated with your latest MX record information. The MX Record Analysis window allows you to query Email Protection or your company's Authoritative DNS Name Server for the MX Records that are recognized for the SMTP server names for a domain. You can then confirm that all the IP records that are configured for your domain's MX Records are correctly redirected to Email Protection. The analysis indicates the following: • All Authoritative Name Servers for the entered DNS name • All MX Records that are recognized by the Authoritative Name Servers - this process retrieves all the MX Records for a given domain • Whether the hostname for each MX Record is a valid hostname, an outdated hostname that will work but should be updated, or an unrecognized hostname which may be allowing email to be routed around Email Protection This window also indicates the recommended values (using the default values configured at the system level for Email Protection) to assist you in determining whether your MX Records are redirected correctly. For example, if all the SMTP servers defined for a domain do not show the same information, this can indicate that your MX Records are not defined correctly. Note: This feature must be enabled at the system level to be available in Email Protection. 1 Click Email Protection | Setup| MX Records.
