<snip> I think what you are saying (traceability and valid sender) can be summed up as good email server management. </snip>
Yes, I believe most of us on the list do this. The point is bringing more awareness to the global community to encourage all admins to do this. <snip> but as many people on the list have pointed out, many server admins don't abide by these practices. </snip> Ditto from above <snip> Ultimately some of this may be "fixed" by a successor to SMTP. This may not be a bad route to pursue, but there's always this thing about backwards compatibility. </snip> I've long advocated a successor to SMTP to deal with the authentication and traceability issues <snip> If a large enough ISP or a group of ISPs takes action to prevent spam and if these efforts prevent enough mail from being delivered or make it a hastle for email to be delivered, it dimishes the utility of email. </snip> Yes, obviously we need to make to make every effort to ensure valid email gets delivered. That's why I suggested a global internet council to support tighter standards. Again, the only way we're going to win this battle is through cooperation. <snip> I think we are only a step or two (at most) away from spammers developing viruses/worms. </snip> They already have. I want to avoid encouraging them to be more active in this area. Again, soliciting suggestions for this. <snip> >1. All SMTP servers verify the sending IP and add it to the headers for >traceability. Some mailservers and ISPs do this, but most do not. >Thankfully, this is something that Declude assists us with. I do this myself, but I can imagine organizations where they may not want this information out there for all to see. </snip> Again, cooperation is needed. <snip> >2. Port 25 blocking for all dynamic addresses with all network providers. ... A subject of much discussion and consternation. I weight dynamic addresses. </snip> With weighting only for dynamic addresses, there is always the possibility that spam can slip through. If we shut down other ways of sending, not blocking dynamic addresses will result in a mich higher percentage of spam getting through. <snip> I think we have several defacto lists out there already. Some of these are free, but I suspect that the better ones will become non-profits and charge a subscription. </snip> None are adequate to the needs. That's why I suggested a global internet council to manage them. <snip> >4. SMTP AUTH required on all SMTP servers, forcing users to properly ... I do this now, but had to get all my users upgraded to correct clients. <snip> We switched about three years ago, but it was well received by our customer base. Yes, all of these suggestions will take some effort, but the end result of this, along with other suggestions not as yet raised, will be significant progress in the battle. How about some new suggestions for methods to combat the spammers? - --- [This E-mail scanned for viruses by Declude Virus] --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
