It should be mentioned that you may lose a bit of legitimate mail this way
however.  Trying to ping Mike off list, my mail wouldn't go through, since
my MS gateways don't know anything about legitimate addresses which are
currently in Exchange 5.5 and not accessable from the inet.  Although my
address is valid, milter-sender rejected it on his end because it couldn't
be verified.  Once I get to Exchange 2003 and can implement milter ahead
here, that problem *should* go away (I hope).  Milter-sender is a good tool,
but if one implements it, be aware that it may bite you on the kiester in a
few cases.

That, of course, is true of any of our anti-spam efforts - it's all an odds
game...
