from the ISPs. I can filter out the relay hosts, ok...but our customers gets e.g. mail from customers of sprint, and I block the incoming connection from customer-mail-relay.sprint.net (e.g.!!!). Well...then I can go and close my business ;)
No, if we want to stop those spammers, the logical idea is, that all ISPs which are housing such spammers must ban them from their servers. They must disconnect every PoP, which is housing such spam customers.
yea... close all PoP's and "I can go and close my business ;)" I don't know how it is in other countries but here most of the customers are POP users. Direct lines ? Geee.. Only bigger companies can afford it. So when u get a spam, its from dial-line. most often.try to find who was it ?
Well, in Germany we have several problems with aol germany and t-online (a service by Deutsche Telekom). What can we do ? Block the connections to aol.com ? block the connections to t-online ?
there is an ISP called Polbox here in Poland. they've got about 50 000 accounts ( people says that ). all these accounts are for free. people can get their www for free too... U can imagine what kind of people are on this server ( free.polbox.pl ).
if I do that, I'm going to get so much angry mails from my customers, that I wish: "Give me Spams..but no more mails from my customers". I don't know the situation in other countries, but blocking is not the answer of our problem.
exactly. appropiate filters should be huge...
We must find an answer, in a quite "commercial sense". Those people, IMHO, stop spamming, if they get an invoice for IP traffic or a letter from our lawyer.
or there is another solution: if all administrators will be consequent ( is it right word ? ), and not to give accounts to people who are on "Great Index of Spammers - year XXXX". :))) but this happens only in heaven :(
well..some of the customers wants to get those mails (yes...it's the truth...I don't know why, I think they're happy to receive email ;))
:)))))
The only way to stop this is, to get a position in the contract between service provider and PoP, or between service provider and customers, that the PoP and/or the customer are billed for such traffic. You know, "money makes the world go round".
special fees for spamming ? :)
One (technical) idea can be, to install two smtp server:
All this does is stop you relaying. You can do this on one server with the no relay patches on http://www.sendmail.org/ if you can get the IP address stuff to work right, though we use two servers for other reasons.
well...we're changing our internal network to a secure server network (SSN). So, my second smtp server is in this SSN and the first smtp server is in front of that network. so, our second smtp can go out, but no one can get in and use my second smtp for relaying :)
yes, but his is solution for a company not for ISP [ when u are at end of line ]. not when u've got connection to 2 or more AS's.
