how to write an anti-phishing ruleset (and test?)

[Jeff A. Earickson]

Gang,

Our alumni office uses one of these click-thru counter services for
the alumni newsletter.  They sent out their monthly newsletter a
couple of days ago and all of their URLs got marked as phishing attempts
by MailScanner.  They were peeved at me.  Now I need to write a
ruleset to exempt the click-thru service and then be able to test it.
A sample bit of URL code is:

<p>See more at <a href="http://www.xyz.com/links/link.cgi?31889|363543|CLY-20041117090021">http://www.colby.edu/eag</a>.</p>

If I email myself this snippet, I can't get MailScanner to bark like it
did for the real message (which came from xyz.com).  Why?  How to test
a ruleset?

What would a sample anti-phishing ruleset look like?  Something like:

    #---exempt from xyz.com->colby.edu from anti-phishing tests
    From: xyz.com and To: colby.edu     no

    #---everybody else gets tested
    Default: yes

An example in the etc/rules/EXAMPLES file would be nice.
