I have got a copy of Henrik's code - I'm not sure on the procedure about
uploading this.
The essential formula is
strtolower(md5(<email>)).<blacklistaddress>
Is the chance of collision introduced by that strtolower() acceptable in this
application?
The strtolower is necessary to mimic the usual behavior of mail & DNS systems.
EG in terms of most mail system's deliver-ability:
jhar...@impsec.org == jhar...@impsec.org == jhar...@impsec.org
IE the DNS system is always case-insensitive and most systems are too WRT
the email ID.
So when a spammer starts playing case-flipperoo WRT their e-mail addresses,
you still want to catch them.
