Adding entries to SMTP security lists

This topic provides information on adding entries to SMTP security lists. You can add entries by domain name or network address.

Note: You can use the Blocked and Allowed lists together to provide the specific functionality you need. For example, you can use the Blocked list to block all incoming SMTP/MIME messages from *.com and then use the Allowed list to still allow incoming SMTP/MIME messages from mycompany.com. You can also use the Domain and Range methods together. For example, if a subscriber record exists on the system for [email protected] (with a network address of 5478265555), you can use the Domain method to block all outgoing SMTP/MIME messages to *.company*.com and use the Range method to still allow outgoing messages to 5478265555 ([email protected]).
