I think http://wiki.debian.org/EximNospam should be removed since it encourages backscatter spam. Thanks, Chuck -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.alioth.debian.org/pipermail/pkg-exim4-users/attachments/20070402/99f2a475/attachment.html

I second that.The page is still there. Will someone please remove it? Should I edit the page saying something to the effect of: The page that was here suggested using what is called challenge response system to eliminate spam. This method often makes you a spammer. Challenge response requires anyone sending you mail to send back a second email verifying that you intended to send them mail. One of the BIG problems with this is spammers forge email and you end up spamming people who didn''t actually send you email. If you run a challenge response system you will likely be blacklisted! See http://en.wikipedia.org/wiki/Challenge-response_spam_filtering#Criticismsfor more information. If you think you can have no spam with exim you don''t understand the problem. The email protocol SMTP was designed for a more trusted environment than todays Internet. The only way I know of to have no spam (100% spam free) and not be a spamer yourself is to not use email. I run mail servers and have been since 1996. To mitigate the problem of spam and reduce spam for our users we currently use greylisting, DNSBL''s, and spamassassin. And some of those users just delete spamassassin scores above 3 or 5 (bayes and AWL off) with procmail and forward it onto to gmail for another round of spam filtering.
