MX Record Lookup and Banner Check

In the MX Record Lookup and Banner Check section, you can perform:

•
An MX Record lookup for a given domain name.
•
A connection check to the resulting host server or supplied IP address to retrieve the SMTP banner.

The DNS servers are displayed by default in the DNS Server 1/2/3 fields; they cannot be changed. The SMTP port is displayed in the SMTP Port field.

When you enter a domain name or IP address, the Comprehensive Anti-Spam Service attempts to connect to that server and retrieve the SMTP banner. This feature allows you to verify that an email sender is not spoofing an address to appear more legitimate.

To look up the MX record of an emailer or domain:
1
Enter the domain name or IP address in the Lookup name or IP field.
2
Click Go. The results are displayed.
