Spam Checklist - April Fool's Day is Approaching
by Berislav Kucan - Thursday, 27 March 2003.
As April Fool's day is less then a week away, filtering company Clearswift is advising organizations to take great care of spam emails that traditionally use this day as a "firestarter". Below you can find a simple checklist connected to spam prevention.

Block offenders
  • Blacklist services hold information about currently reported spam servers and known offenders.
  • IT managers should block servers and IP addresses that have previously sent spam.
Find out if the sender is "real"
  • Verify that emails are sent from valid domains.
  • Verify that the "sender" is able to receive real email, as spammers do not wish to receive returned mail.
Learn the "style" of messages
  • Reject messages with large numbers of recipients in the "to" field, as they are likely to be spam.
  • Use content analysis to filter out emails containing typical spam topics such as dieting advice or loan offers.
  • Incorporate predefined spam expression lists, such as "Lose pounds!," into content analysis engines.
  • Deploy content analysis across a wide variety of languages, as spammers exist across the globe.
Prevent your site from being used to spam
  • Protect yourself from spammers who bounce their emails around other organizations' servers in order to conceal their identity.
