Re: spamd greylisting, masking on /24

You really do not need to do this in spamd. Do it in pf.
i.e:

table nospamd persist file /etc/mail/nogreylist
...
no rdr $ext_if proto tcp from nospamd to $mailserver port smtp

 I seem to remember seeing a patch to spamd that makes greylisting only 
 look at the first /24 of the address, but I can't find it after fairly 
 extensive searching with google/marc. Does anyone have a copy they 
 could point me at?
 
 The whitelists on puremagic.com (on which greylisting.org's lists are 
 based) don't list networks with a common spool unless more than a /24 
 is involved (there are some /24 listed with other factors requiring 
 whitelisting, e.g. unique sender addresses per delivery attempt).

Been doing that for months, but it takes quite a while to add enough 
networks to be useful, and there's always another round the corner. I 
don't think I've seen any up-to-date 'greylisting whitelists' that 
include common-spool senders from /24 and smaller, but those are 
responsible for most excessive delays I've seen. (The other delays I 
see are usually shorter [2-4h or so], mostly from ISPs using Exim 
shunting delayed mail off to another host to shorten queues on their 
primary relays and not bothering to retry for a while).

Practically, I've never found any need to use anything beyond the
greylisting.org whitelist in that manner, as well as ensuring I'm
running spamlogd correctly so that outbound servers get whitelisted..
At least with our 70,000 lusers worth of mailboxes.
