Whitelisting doesn't appear to work

[Tony Stocker]

Hello All,

I've set some entries in /etc/MailScanner/rules/spam.whitelist.rules
because I have had several messages marked as spam that were actually
the MailScanner "Virus Detected" messages.  I'm modifying the
addresses slightly to protect myself, but let's say that my
mailserver's address is "197.100.235.132", this then is the entry that
I have in the spam.whitelist.rules file:

From:           197.100.235.    yes

However, I am still getting "Virus Detected" messages marked as spam,
(see slightly munged example below) even with this entry.  What am I
doing wrong?
