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. :-) Sarah -- "To speak another language is to possess another soul" - Charlemagne
