tricks to cutting down on spam
Tricks to Cutting Down on Spam
  • look for the full Internet mail header
  • depending on your mail server, you may have to work at finding out
  • look to see what the last received element is
  • that address will be written in this format: opt.ispam.net (211.188.122.11)
spam reducers whois
Spam Reducers: Whois
  • then use the Whois service at http://rs.internic.net/whois.html
    • enter the IP address using "network 211.188.122"
    • note the last section of the IP address is left off
    • this will tell you who posted the message
tricks continued
Tricks, continued
  • never, never respond to spammers
    • not even to ask them to take you off the list
    • they then identify you as someone who reads your email
    • they will continue to send you email
    • create more than one account
      • use one of your accounts to download software
    • keep one account for friends
    • keep one account for business/work
involving your isp
Involving your ISP
  • forward spam to your ISP for action
  • complaining to your ISP or to the ISP of the spammer’s site helps
  • an ISP may drop or block the offender
involving the spammer s isp
Involving the Spammer’s ISP
  • write to the postmaster at the sender's site
  • find the line that begins, "Message-Id:”
  • remove the information in front of the @ and key is postmaster
  • so your message would be addressed to: postmaster@example.com
  • include the original message with the full headers of the mail intact so the sysop can determine what the problem is and take action
opting out
Opting Out
  • You can request that your name be removed from the Direct Marketers’ Association
    • DMA's e-Mail Preference Service
    • http://www.e-mps.org/en/
  • However, it then becomes your responsibility to make the request
  • much junk mail is generated from organizations who are NOT members of the DMA
software programs spam hater
Software Programs: Spam Hater

tricks for webmasters
Tricks for WebMasters
  • if you run a Website, use a company or non-personal account
    • Websites are great places for spammers to grab addresses
    • you already manage high tech equipment, are a decision maker, and likely have influence over purchases
tricks for listowners
Tricks for Listowners
  • if your list gets spammed or you have a problem poster, nip that in the bud by blocking their postings
  • don’t toss them off the list (what sane person would keep someone from getting information?)
  • instead, block their messages
  • that usually frustrates them enough so that they’ll quit the list
other methods
Other Methods
  • filters
  • knowing who the main spammers are
  • legislation
garbage filters
Garbage Filters
  • this software works by scanning for specific character strings or addresses
  • use the software to write the suspected spam messages to a “spam” or “trash” folder for checking over before you delete them
filters
Filters
  • these compare text that you’ve entered into the filter with email messages coming in and discard the ones you don’t want
    • e.g., type in the address of the spammer and instruct the filter to discard those postings
spam attack pro
Spam Attack Pro
  • software with the email addresses of about 400 of the best known spammers programmed into the software
  • you can also add addresses and subject headers to the filter as necessary
filters caution
Filters...Caution
  • these work very well, but
  • filters can screen out items for which you never thought to ask
  • serendipity should not be screened out of the process of acquiring information
major spammers

small claims court
Small Claims Court
  • federal law (47 U.S. Code, Section 227) authorizes damages of up to $500 per copy for receiving unsolicited faxes and other electronic communications
  • you can sue in small claims court but since most of the spammers are usually fly-by-night outfits, you may be unlikely to collect
zero junk mail
Zero Junk Mail
  • http://www.zerojunkmail.com/
  • this company will contact advertising firms and direct marketers on your behalf and ask them to remove you from their lists
spamcop
SpamCop
