Milter-greylist

I'm currently checking out the functionality of milter-null and have 
arranged it in sendmail.cf that it is carried out before milter-greylist 
(InputMailFilters). However, it seems that milter-greylist gets carried 
out before milter-null. e.g. connects with <> senders from joejob bounces 
or spam with <> senders get greylisted although they should normally get 
quarantined by milter-null. That means in some cases that the mail server 
gets hammered with connection retries, especially when the originating IP 
no. has been delayed by policy longer than usual.
Is there a way to make sure that milter-null can first make a decision 
before greylisting kicks in or is that impossible?
