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

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

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. Rather we are trying to find a open source solution that works well against spam.
If you are saying... good and thanks, but without the help of the good ISPs is that possible? Look for that. I took the HEADER POSTED BY YOU and made a research. Note the existing structure behind this spammer (links below). There are all kinds of support, courses and tools, to enable spam. Including how to avoid spam box.

Include domains on blocklist will resolve or mitigate this hell created by greedy Sociopaths and predators?
Guys, we can divide the history of capitalism in before and after the email marketing. 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
