I find that perventing others to send spam to you is not posible. Since parts of the header (e.g. To, cc, ect.) are most often forged. The only real thing that can be done about this is sending a complained to the ISP. Make sure you include all headers along with the body. I feel that not every spam email sould be reported to the ISP. For ad I usaly do send a report. The headers are most often forged ligthly. Sending a compained to the users them self don't work and can cause more spam. For normal user SPAM, i usaly send a complained to the user. The headers are most ofthen not forged and it does often work. (Much more civile this way) A way that you can track down the ISP is thwough www.abuse.net (web-lookup or 'whois -h whois.abuse.net hostname', i have made a alias for this) If this doesn't work, then you can always use the standert whois lookup or a tracerout to find the ISP. > > I know some people think this is OT for this kind of list, > but it is a problem for anyone on any list, and I feel it is > legitimate to try and spread ideas on fighting this horrendous > waste of time and resources. This is OT in the way that it has nothing to do with FreeBSD. However it has to do with the mailing list it seld. I like to see the number of SPAM seeing reduced. What would be instesting is to see what can be done at the FreeBSD hubs to reduce spam.
