Milter-greylist

hi all 

i am using milter-greylist ver 1.5.6 
it seems that the senders address is cutting off
after 30 characters. so some rules 
defined in /etc/mail/greylist.conf didn't work

is there a bugfix or workaround 
to increase the string-length for 
example to 64 

best regards 
hans
