RE: Harmful spammers
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. It isn't. 2) Every time you get spam, locate all the hosts it came through in the header. Or alternatively just report it using Spamcop (http://spamcop.net) or some other reporting tool. Life is just too short to do this by hand every time you get spam. On the Haskell mailing list we have a good compromise at the moment: the mailing list software's auto-filtering catches most of the spam (not allowing Bcc's to the list is a good one), and for any spam that gets through I just add it to the list of disallowed addresses. I asked recently if we should move to allowing subscriber-only posting, and I got a small number of responses, which were split roughly 50/50 so no action was taken.

CAUCE (The Coalition Against Unsolicited Commercial Email) seems to me a nice alternative. Check www.cauce.org.

I think moving the list to allowing subscriber-only posting may cause some trouble to the subscribers too...

Harmful spammers
Sorry for the pollution. Is there a way to kill the guys from: @bid4placement.com ? They managed already 3 times to block my mailer with their HTML, via Haskell list. Jerzy Karczmarczuk Caen, France ___ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell

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

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. Note that spammers add dummy entries to the Received: list. The server previous from your trusted maildrop is usually the one to address. Given a site name of foo.bar.com, my usual list of addresses is : You can also look up people responsible for the domain with the 'whois' command. Many places simply seem to ignore mail sent to e.g. postmaster, but people in the whois database tend to be real. 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 I'd advise against that. A polite complaint is in order, but there's no need to be deliberately nasty. And there's also a good chance you're hitting the wrong persons, and/or alienating those with power to deal with the spammer. -kzm -- If I haven't seen further, it is by standing in the footprints of giants ___ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
