There are a couple things to do that can at least cut down on spam.
1) Make sure that your mail gateway, or (in this case) the mailing list host is not an open relay site. Check http://www.mail-abuse.net/ and especially http://www.mail-abuse.net/rss/ for more information. 2) Every time you get spam, locate all the hosts it came through in the header. Check both hostnames and ip addresses as one of the common spammer techniques is to give a different hostname than the ip address maps to. These are in the "Recieved-by:" headers. Then send mail to everyone reasonable at the site you get. If there are any mail addresses in the body of the message, add them too - similarly with web addresses. Given a site name of "foo.bar.com", my usual list of addresses is : [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] I have a program to generate this list, as often I send mail to several sites at a time. In that mail, complain about the spam and include the entire mail message that you got (including the headers). (If I get really bugged - for example by getting the same spam over and over again, I'll often include a huge image file that contains the text "SPAM IS BAD" just for amusement. This technique is for experienced drivers on closed courses only. Don't try this at home.) If your MUA supports changing your "Reply-To:" and "From:" headers, change them to something nonsensical. Ignore mail bounces. Often the sysadmins will do their best to fix the problem, however, many recent spams have originated in China and they don't seem to be doing much to change that. jefu -- jeff putnam -- [EMAIL PROTECTED] -- http://cs.eou.edu/~jefu _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
