I run greylisting on an email server with several thousand email
accounts and think its great. Reduced system load drastically. I
also have a perl script I have wrote that runs every minute and looks
at all messages that arrived in last 60 seconds and if spamassassin
gave them a score of less then 5 it adds the sending MTA to a
whitelist. It also removes any from the whitelist that have sent a
message that scored over 5. The whitelist goes back 6 months and is
continually refreshed by the script. The whitelist typically has 40K
IP's in it.
As a result no one even notices the greylisting, AFAIK...
Is that the greylist whitelist or the SA whitelist?
