Milter-greylist

Based on Emmanuel's email, I just rtfmed the README file of 3.1.6
and noted the stat command.  I have taken the example[1] in that file
and added it to the greylist.conf file.

[1] stat ">>/var/log/milter-greylist.log" "%T{%T}    %i:%s:%f:%S\n"

Now I get an output at /var/log/milter-greylist.log:
...
23:39:39    196.204.150.141:%s:stocknews@...:tempfail
....

not sure why the %s is not showing the sender.  I am running sendmail
8.14.0.
