Greylisting no longer working ?

Thanks for your follow-up. I tried upgrading again, and grey-listing 
stopped working. I then restored only the "libexec" directory from the 
backup, and grey-listing works again!

The dcc_conf file wasn't touched while upgrading, and the difference 
between and the current one are only minimal:

     vps183:/var/dcc # diff dcc_conf dcc_conf-new
     < # from Rhyolite Software DCC 1.3.45-1.55 $Revision$
     > # from Rhyolite Software DCC 1.3.49-1.57 $Revision$
     > #   For example
     > #DNSBL_ARGS="'-Bset:rej-msg=5.7.1 550 mail %s from %s rejected; 
     > #   checks SMTP envelope senders and URLs in mail message bodies 
in the XBL.
     < # external filter -X parameters for dccifd and dccm
     < XFLTR_ARGS=

I really don't know what to do now. I even tried deleting all the cache 
files prior to upgrading.
