Hi all,
I had a question about greylisting (with spamd) in production.
I've successfully run spamd on firewalls (as a frontend to either barracuda or
SpamAssassin) and have really liked the reduction in SPAM volume.
Unfortunately my employer's wife does not like the delays that this introduces
into our mail delivery, since she uses email for quick turn-around
communication.
The main problem occurs with senders like Gmail, yahoo, hotmail, etc. ...i.e.
all the senders that have large farms of smtp servers from which they can retry
delivery after initial greylisting delay.
I know this means I'm not doing proper whitelisting of those major sender
domains, but I'm at a loss on how to best construct and maintain such a
whitelist.
Are there any up-to-date lists that already track the MTAs of these large mail
providers?
Or will this mostly be a DIY effort on my part?
Any thoughts/insights/experiences would be greatly appreciated.
I used to use an rsync'ed uceprotect.net whitelists. then feed them into
manual-white table of my pf.
works as a charm.
