How many machines were infected by email viruses, worms or trojans? How many had to be cleaned from some thing user got from web? I have email address known only to some coworkers. It was never published on the net. Used only for one-to-one personal messages. Address gets spams for more than a year. Started getting spams after coworker got Sobig or other related worm. > Your immediate attention regarding this matter will be highly > appreciated. There are several tools that can reduce number of spam emails that reach your mailbox. 1. Add RBL filtering in SMTP server. It will disallow access to your server from known spammer addresses. See FEATURE(dnsbl) in your email server's documentation. spamhaus.org and cbl.abuseat.org provide basic RBL lists. If you want more aggressive filtering, check njabl or sorbs blocklists. These organizations provide dialup RBL lists that can filter most of hijacked DSL hosts. There might be false positives in dialup lists and user might need 48-72 hours to get off Sorbs list. 2. Use antivirus scanners. Check Amavis-new 3. Use email content scanners. Check SpamAssassin, Dspam or CRM114. If SpamAssassin or Dspam stores user configuration in database, user settings can be controlled in SquirrelMail sasql plugin. 4. Use Bayess filtering. Bayess is part of SpamAssassin. There is SquirrelMail plugin that implements similar features. 5. Use TMDA. Please note that TMDA only prevents unconfirmed email from reaching your mailbox. It might be annoying to other email senders. 6. If you don't care about delay in email delivery, check greylisting tools. -- Tomas ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
