Yes if you use the tests for pipelining/bare_newline/non_smtp_command.
Otherwise, use whatever is the larger one of postscreen_dnsbl_ttl
and postscreen_greet_ttl.

The cache size depends on the number of unique IP addresses that
it needs to remember, and that number is different for everyone.
I suggest that you pick a memcache ttl value, run Postfix for that
amount of time, look at the actual cache size, and then reserve
space for 10 times that.
