Milter-greylist

Dear all,

I'd installed  <milter-greylist> and <milter-regex> with sendmail on  
the same FreeBSD machines.

I wonder if there are obvious differences in performance (and others, if 
any) on the issue of the
running order of <milter-regex> and <milter-greylist> with sendmail. 
--That is, if there are difference between the following two 
configuration  sendmail options:  (sendmail.cf)

> O InputMailFilters=greylist,milter-regex,clamav        (e.g.,  running 
> greylist first)

> O InputMailFilters=milter-regex,greylist,clamav      (e.g., running 
> milter-regex first)
