You know the sort pills, lost money, cheap software, bigger appendages. I do not trust anti-spam programs in case they band some mail that I want., Here is my idea. A group of ISP's world-wide get together and form an association. They all promise to remove any customer (close their account) of theirs that sends out spam. So, if you are with an ISP that is in this association you will have the benefit of much less spam. If you do receive spam you can report the spammers ISP to your ISP which will then request that their customer is removed. I predict that if some ISP's world-wide adopted this plan and pushed it they would get people to sign up with them and more ISP's would want to join the scheme so that the only ISP's left not in the association would be the ones sending all the spam (to each other !) It is time someone made a stance as all the legislation in the world will not stop spam as many ISP's like having these guys as customers. What do you think ? I will be sending this idea to my ISP.

This might work, except the likelihood of getting all the ISPs in the world to go with this is probably a little shortsighted. You will also get the problem of people being wrongly disconnected for being infected with a mass-mailer trojan - the user didn't 'actively' use their PC to spam people, they just weren't too PC savvy. Also what happens if an ISP not in this union sends an email to an ISP within the union? It's not as if anything will be done at the ISP of the sender, it would also be really irresponsible for ISPs to just stop accepting email(s) from those not within this little group. There are systems like this already in place - Hotmail/Goodmail and the likes where you can pay Hotmail ~$1,400 per year to ensure none of the emails from your domain gets blocked by their spam filters. If anything, what should be better adopted is greylisting (www.greylisting.org/). It pretty much works at the receiving level on a known hosts lists. So if you send me an email, I'll tell you "Sorry, I can't deliver it now - try again in 5mins" and will note down your IP Address. When you come back in 5mins, I'll have your IP address listed and will let you send your message through. This works because a lot of spam sent from mass mailing programs only loosely incorporate the RFC for SMTP - pretty much these mass mailers don't understand when a mail server rejects because it's unable to deliver and just handles this as a delivery failure - it doesn't know it should try again. Greylisting has already been setup in places like the University of Auckland and it works quite well for managing their spam levels. Alternatively, look into Sender Policy Framework (http://www.openspf.org/) - this works at the DNS level. You pretty much specify which mail servers are allowed to send email for your domain so by process of elimination, any mailserver not on that list which is sending mail for your domain is [possibly] doing something it shouldn't be doing and so you can either tell your mail server to drop the message or flag it as spam.

584060	2007-08-23 11:57:00	Or get Gmail, 2 piece of spam in two years :eek::thumbs:	beeswax34 (63)
584061	2007-08-23 12:07:00	Or get Gmail, 2 piece of spam in two years :eek::thumbs:Huh? Hmmm (www.imagef1.net.nz).	Greg (193)
584062	2007-08-23 12:20:00	The best solution I've seen is HashCash (http://www.hashcash.org). The idea is that to send an email your computer must perform a series of pointless calculations but can prove by doing so that it wasted a certain amount of computation time to create the HashCash "stamp". The system is based on cryptographic principles and short of a major break in the hash function you cannot forge the stamps. Normal users can afford to waste a second of processor time to generate a stamp for an email message, especially since it can be done in the background as the user types it. A spammer, however, will have their maximum mailing rate axed thousands of times if they attach these stamps. Some spam filter software will already detect and automatically whitelist email with hashcash attached.	TGoddard (7263)
584063	2007-08-23 14:51:00	Wow Greg!, who do you handout your email to? The last spam messages that I remember having was a couple of months back and that too TV3 newsletters. I don;t even have filters so I don;t know why I get so few (not that I'm complaining in the least) My email goes out quite a lot as well so...	beeswax34 (63)
584064	2007-08-23 20:59:00	Similar to Greg (www.imagef1.net.nz) - but that's why I have a gmail account. It's great to use for those 'I wonder' type sites because filtering is so great. I haven't 'received' any gmail spam for as long as I can remember - it all stays of the web and just my good email gets downloaded	johcar (6283)
