I see your point, but we are experiencing 0.04% false positives.

I had forgotten about that, because I did not get a chance to proceed
because I do not have pcre installed, and I don't know how to re-write
it into regexp.

This is what you posted:=20
/\bhttp:\/\/[a-z0-9\-.]+\.info(\.\s|(\.)?$|[^.])/ REJECT

When I have my backup system finalized, I will re-build Postfix with
pcre support. In the meantime, I will try some of the other
suggestions.

Thank you Magnus.
