Right. But what's the problem with that? The existing
license is perfectly acceptable.

Why do you think something has to be changed?

Please excuse me, but that's nonsense. Adding such a
clause does NOT add any value to the license. Instead,
it makes it more complicated, without reason.

Removing that clause would make the license a so-called
"2-clause BSD license". The most important difference
of that is that it would be GPL-compatible. The current
license (with the 3rd clause) is not GPL-compatible.
Emmanual has to decide himself whether he wants to change
that and make milter-greylist GPL-compatible. However,
any contributors whose code is included in milter-greylist
would also have to agree to such a change.
Personally, I wouldn't change anything. Past experience
with other open-source projects shows that license changes
often lead to problems. Therefore I recommend to change
it _only_ if there's a very good reason to do so. There
doesn't seem to be a good reason here.
Just my 2 Euro cents. :-)
