I already told you what is available and also that they all require a considerable amount of tuning. Besides what you're mentioning is all av and not really spam filtering --srs > On 11-Oct-2015, at 2:41 PM, Suman Kumar Saha <suman at bdcert.org> wrote: > > Hi. > My point was current popular open source tools like Mailscanner/Amavis not working perfectly to fight against spam.So I expect someone from the working group can share better anti spam tool.We extremely disagree to give business opportunity to anti spam solution provider like barracuda or to others.Rather if we can enrich open source tools that will really be benefited for the community. > > Thanks > Suman > >> On Oct 10, 2015, at 11:38 PM, Marilson <marilson.mapa at gmail.com> wrote: >> >> Hi >> >>> Mailscanner/amavis with clamav can not protect spammers very well >> >> Sorry, I did not understand this frase... >> >>> ip block lists are a first and still quite useful line of defense. >>> Can you share which open source anti spam application works well. >>> We do not want to let them do business with spam by taking cloud based solution like zero spam/comodo anti spam.

This e-mail marketing is an aberration, a distortion of the capitalist system, and is worse than the financial capitalism that creates resources without generating corresponding riches, and from time to times the bubble explodes and the losses are distributed equally among all, as if we live in a communist system. Similarly e-mail marketing does not create any wealth, only directs people misinformed to buy a good that needs, in one or another place. And do it in a way that borders on sociopathy, without respect for people, sending again and again, ad infinitum, the same junk. >> >> Thanks >> Marilson >> >> >> -----Mensagem Original----- From: anti-abuse-wg-request at ripe.net >> Sent: Saturday, October 10, 2015 10:58 AM >> To: anti-abuse-wg at ripe.net >> Subject: anti-abuse-wg Digest, Vol 48, Issue 12 >> >> Send anti-abuse-wg mailing list submissions to >> anti-abuse-wg at ripe.net >> >> To subscribe or unsubscribe via the World Wide Web, visit >> https://www.ripe.net/mailman/listinfo/anti-abuse-wg >> or, via email, send a message with subject or body 'help' to >> anti-abuse-wg-request at ripe.net >> >> You can reach the person managing the list at >> anti-abuse-wg-owner at ripe.net >> >> When replying, please edit your Subject line so it is more specific >> than "Re: Contents of anti-abuse-wg digest..." >> >> >> Today's Topics: >> >> 1.
