Use 'deny' rather than 'drop'. 'Drop' pulls the plug on the session,

MTA. Whis is a problem in the case of false positives, and may trigger
an unwanted retry cycle.

Check the T&Cs of the DNSBLs you're intending to use. Some want you to
do this, some insist on it, others don't want you to do it at all.
