Rules for Virus Scanning

[System Administration]

Hello All

I have recentley added a rule to the mailscanner config file telling it
that if mail comes from a certain IP address to not bother scanning it.
Upon checking the mail logs I have noticed the following error:
    Config Error: Cannot match against  destination IP address when
    resolving configuration option  "virusscan"

The mailscanner config file looks like this:
    Virus Scanning = /opt/MailScanner/etc/rules/viruscan.rules

The rules file contains the following:

FromTo: 12.129.199.61   no
FromTo: 63.161.60.29    no
FromTo: 63.161.60.61    no
FromTo: 63.161.60.93    no
FromTo: 63.211.220.125  no
FromTo: 216.35.189.221  no
FromTo: 216.148.222.61  no
FromTo: *@pris.ca       yes
FromTo: *@pris.bc.ca    yes

When I don't use a ruleset, everything appears to work fine and I don't
receive any errors. However I need the ruleset to prevent the
Mailscanner from scanning the same piece of mail twice.

Another error I have noticed which does not have anything to do with the

above is the following:
    Global symbol "$file" requires explicit package name at (eval 496)
    line 1, <GEN1720> chunk 3.

Any and all help is most appreciated.

Thank you

Rick
