Simple: if in doubt, never use "drop". Always use "deny".

"drop" terminates the connection in an "unfriendly" way and should really
only be used if you're sure you know what you're doing (e.g. you're 100%
certain you're dealing with spamware/an attacker of some sort, and one
which is unlikely to retry).

If used (even in error) on "real" messages, "drop" will probably cause
*more* resource usage for both you and the sending end, and additionally
quite possibly cause problems that are difficult to diagnose - you will
not endear yourself to other administrators.
