Aargh, my first false positive in months!
It found the numeric IP addresses mentioned in my previous reply to this
thread, discovered I had put too large a score (6) on the
NORMAL_HTTP_TO_IP rule and binned the message.

Oops.

For any others who also didn't get my reply, here it is (more or less)
again:

I have changed the phishing net so that it marks numerical links (where
the two numbers match) with a different warning message.

Add this to your /etc/MailScanner/reports/en/languages.conf (or
equivalent) file:
NumericLinkWarning = <font color="red"><b>MailScanner warning: numerical
links are often malicious:</b></font>
(That should all be on 1 line)

and apply the attached patch to your Message.pm.

This is for 4.40-11 and I don't guarantee your success if you try to
apply the patch to other versions unless you do it by hand.
