Milter-greylist

I'm getting this error from milter-greylist for some messages:

smfi_getsymval failed for {if_addr}

It seems it happens each time a message is from 127.0.0.1. I'm not sure 
from the code whether this happens each time an IP doesn't have a 
hostname. I suppose not. 127.0.0.1 has a hostname in /etc/hosts, anyway. 
It happens only on two machines which have the same (older) platform and 
sendmail.
What could be the reason?
