[Greylist-users] Getting greylisting going on a new Debian

Thu Jun 26 14:11:57 PDT 2008

Had to do some fixing, looks like the lines exist...

hermes:/etc/mail/greylisting/relaydelay-0.04# vi xlist.pl
hermes:/etc/mail/greylisting/relaydelay-0.04# ./xlist.pl white ip 192.168.1
Loading Config File: /etc/mail/relaydelay.conf
Similar Record already exists!  Aborting.
hermes:/etc/mail/greylisting/relaydelay-0.04# ./xlist.pl white ip 127.0.0.1
Loading Config File: /etc/mail/relaydelay.conf
Similar Record already exists!  Aborting.
hermes:/etc/mail/greylisting/relaydelay-0.04#

Since this product is pretty much abandoned, is there anything else ppl would recommend as moving to?

regards

Steven

It used to be part of the CVS on the puremagic web page, but the link is now 
broken. I THINK this copy is unchanged, just fix the user name and password 
to access the database and it should be good to go.

#
# File: xlist.pl
#
# Version: 0.01
# 
# Programmer: Evan J. Harris <eharris at puremagic.com>
#
# Description:
#   Will create manual white or blacklist entries in the greylist database,
#   with some basic checking to ensure this isn't a duplicate, and to 
#   expire existing rows that would match.
#
# References:
#   For Greylisting info, see http://projects.puremagic.com/greylisting/
#
# Notes:
#   This is a quick and dirty implementation, and no doubt can be made
#   much nicer, but it works pretty good as-is.
#
# Bugs:
#   None known.
