At a previous employer we used both the Team Cymru feed and the Spamhaus
DROP and EDROP lists to block badness and about twice a year at first we’d
see our own customers listed on the Team Cymru lists then we’d see none in
the year. I was at that place for over 10 years.  The Team Cymru list was
enabled 8 years ago now and Spamhaus DROP and DROP lists were enabled about
3-4 years ago.

The Spamhaus DROP and EDROP lists never listed our own customers and just
seemed to list serious badness with no false positive issues that I can
recall.  At first we used the /32’s on the DROP and EDROP lists only and
then later we started allowing the larger prefixes into our routing without
any disputes or false positives.
