One user or 5 million users, it's all the same to us (i.e. there is no
charge).  You can read the license (or forward it to those concerned) if you
like, which says the same thing, but in many more words <wink>.  (You can
even repackage it and sell it yourself if you like - it's very


(A copy of this is included with the source archive, and probably ought to
be with the binaries.  I'll look into that).

Legally (in terms of using the software, anyway) there are no worries at all
(although you don't gain any rights to sue us if something goes wrong, which
maybe you can do with commercial software in the US, I don't know).

I know almost nothing about IHateSpam, but if I understand correctly, it's
basically just whitelisting, yes?  (i.e. it filters out mail from people you
don't know).  This is a fairly weak approach, but popular :)  SpamBayes
doesn't have any whitelisting (the very long story is in the FAQ), but if
you really wanted it you can purchase InBoxer which is a spambayes-based
product (one of the initial developers did the repackage-and-sell things as
above) that does have a few extra things like whitelisting.

In any case, if you're doing client-side filtering, letting them all use
their own shouldn't be a problem.
