%vars% in rules

[Chuck Foster]

    [ The following text is in the "iso-8859-1" character set. ]
    [ Your display is set for the "US-ASCII" character set.  ]
    [ Some characters may be displayed incorrectly. ]

Having pondered over this for a while in the source, it would seem that you
can't do something like this:

        From:   blah at somewhere.com and To: %mydir%/ruleinfo
%myotherdir%/message.txt

Reason I was looking at this is several customer details are compiled
together, and where they have multiple domains I was considering one regexp
file for them instead individual lines, but as the location of the rules
might vary from MailScanner implementation to another using a percent var
seemed a handy way to do this ...


Would it break things absolutely horribly to do variable expansion before
any other rule processing, something like:

        sub Store1Rule {
                $_ = shift;

                ...

                chomp;
                s/\%([^%]+)\%/$PercentVars{lc($1)}/g;
                s/\${?(\w+)\}?/$ENV{$1}/g;
                s/#.*$//;
                etc etc etc

which would in principle allow some items to be set up in MailScanner.conf
which can then be reflected in rulesets later on?

Maybe that's too dangerous ... !
