7.5.1 To Configure Mail Access with MMP

The MMP does not make use of the PORT_ACCESS mapping table. If you wish to reject SMTP connections from certain IP addresses and you are using the MMP, you must use the TCPAccess option. The syntax of this option is the same as mailDomainAllowedServiceAccess (see Sun Java Communications Suite 5 Schema Reference). It is also described at 23.7.2 Filter Syntax.
