Create another filename rules file containing
allow   .       -       -
which will allow *everything*. Call it

Then in MailScanner.conf put this:
Filename Rules = /etc/MailScanner/rules/filename.rules.rules
(that filename needs to end in .rule or .rules or it can't work out what it

In /etc/MailScanner/rules/filename.rules.rules put this
FromAndTo:      *@abc123.com
FromOrTo:       default                 /etc/MailScanner/filename.rules.conf

The first line matches all mail whose from *and* to addresses are in
abc123.com, and gives the "allow all" set of rules. The second line
provides the default set of rules, for everyone else.
