Re: [swinog] Policy of blocking spam vs. flagging

Hi all

We recently implemented greylisting and now our customers hardly get spam anymore. Coupled with a decent whitelist of known mailservers and auto-whitelisting of outgoing email, it works wonders. Greylisting also takes a lot of load from the virus scanner and from spamassassin, which is used to tag the remaining spam mails.

Taking load from Spamassassin is also the main reason why I implemented greylisting on our scouting mailserver.

The Graphs show how much load was taken: http://spamkiller.scout.ch/index.php?view=_spamno_checkvirusmail_inskip_chec...

I did whitelist almost all known mailservers (From IMP Whitelist and a few more) as it does not make sense anyway to greylist them.
