Unfortunately, some well-known ISPs, especially Psi.Net and UUNet, but several others also, continue to give these guys internet connectivity. Customers of these providers are starting to discover that they are losing mail connectivity, so let's hope the AUP-ignoring ISP's will lose in the (not too) long run.
If someone could suggest how to identify a spammer *before* they start sending out email, then I am sure every person who has to deal with the spam would be most gratefull, it will save them alot of time and money.
When an ISP sells a connection to a company, they have no idea what the customer will use the connection for. Certainly, here at UUNET, our AUP is enforced. But if the spammer just buys another connection, how would we identify them? All the outside world will see is "another UUNET connected spammer", but to us, this is a separate customer.
One soluton that I aiming for (not implemented yet!) is tying our SMTP server into our database. When a customer connects, we look them up in teh db based upon the MAIL FROM:<> value. from the db is returned a max limit of RCPTs that the user may issue for a single mail. New accounts can be given a value of 15 and incremented automatically by say 10 each month as our trust of them develops. If people want to run mailing lists etc.. then they can phone/email us and we can manually up the limit, after making appropriate checks first. Biggest problem in this is ensureing people have legal MAIL FROMs Regards, aid -- Adrian J Bool | mailto:aid@u-net.net Network Operations | http://www.noc.u-net.net/ U-NET Ltd | tel://44.1925.484461/
