Yep. You'll see messages like this in your logs:

milter-greylist: STARTTLS succeeded for DN="xyz", bypassing greylisting

Which is really quite reasonable. Any system, even if it is a spammer, that can 
do starttls is also quite capable of retrying, so will ultimately get past a 
greylist anyway..
