Re: [OT] Harvest netblocks of good MTAs from SPF for whitelisting from greylisting

first i would say yes if doing the sort of greylisting you are talking about pre-whitelisting ips from spf
records is not a bad way to cut down on initial delays

secondly i would say if the ip(s) is not available via an spf record do not assume 'a mx' as 'a' largely NEVER is
a legit mta its usually a website, b MX has usually at most 1 ip that sends most others are receive only, and
often all are receive only

thirdly yes this will save your greylisting work/initial DB build, but also greylisting equally will not
reduce the spam much as most modern spambots will also retry later so will also pass greylisting (why they
do this and TLS nowdays)

fourthly you should still use spf/dkim/spamassasin-at-data/etc on your mta for connections that have
come past greylisting because still a lot of spam comes via greylist-passing bots and legit mailservers
with compromised users

either way this use of SPF is not relevant to this list really?

as greylisting done properly is not a concern for legit senders as it just delays their first email via each
server for each new greylisting user. so less than any % of use

Harvest netblocks of good MTAs from SPF for whitelisting from greylisting

Hi,

I'm configuring greylisting with pf(4) and OpenBSD spamd, and one of
the things I would like to do is explicitly whitelist good MTAs of
e.g. google.com, apple.com, ebay.com, schwab.com, freebsd.org,
uwaterloo.ca etc.

It seems like with the proliferation of SPF, this might be relatively
easy to do: the netblocks of many valid email servers are individually
published by each respective domain through various SPF-compliant
records.  (And even when there are no explicit "ip4" or "ip6" records
with the IP addresses or netblocks, an explicit or implied "v=spf1 a
mx" could still do the trick.)

What's left is to have a list of "good" domains, and a script that
will go through all such domains once a week to compile the list of
good netblocks.  Such netblocks could then be exempt from any kind of
greylisting, such as to never delay the mail from trustworthy domains
whatsoever.

Cheers,
Constantine.
