User-Defined SMTP Server Lists

* 
NOTE: You can modify, but not delete, the RBL User White List or the RBL User Black List.

The User Defined SMTP Server Lists section allows for Address Objects to be used to construct a white-list (explicit allow: RBL User White List) or black-list (explicit deny: RBL User Black List) of SMTP servers. Entries in these lists bypass the RBL querying procedure.

For example, to ensure that you always receive SMTP connections from a partner site's SMTP server:

Select the type of host from the Type drop-down menu. The following setting(s) change, depending on the host type selected.
