Hi all!
I created a bash-script to analyze and clean up my greylist. Maybe
someone needs one which
reports what has been done or just check the greylist without deleting.
I use this one, because a simple find over 90 Domains and 2k
Mailaccounts caused high
server load, this step-by-step processing didn't - if there's not a
million entries in one
domain. ;-)
Greetz,

#!/bin/bash
#
# What's this:
# This script was created to keep the greylist of spamdyke
# up 2 date and remove old entries. On a server with 1k mailboxes
# it works fine and is in productive use.
#
# Note:
# As this script is removing files whithout any possibility to
# undo these deletions, we recommend to try out the script
# with set debug-flag below to see what will be purged.
#
#Location of your greylist
greylist=/var/qmail/spamdyke/greylist
#Number of days to keep greylist
daystodel=28
#Set this this to 1 to see the results without removing any file
debug=0
#Report summary in the end
report=1
#Everything is set up now, let it run!
#nothing needs to be modified below this line (i hope)
