  2. Greylist
  3.         Whitelisted IP
  4.         Whitelisted Email Address To
  5.         Whitelisted EMail Address From
  6.         Whitelisted Email From Domain

  11. Local Emails TO Blacklist
  12. Country Blacklist
  13. Reject No Reverse DNS
  14. Reject Empty Mail From
  15. Reject Same To From Email address
  16. Reject if Recipient's email in Honeypot email list
  17. Reject if IP in Honeypot-generated auto-ban list
  18. Reject Same To From Domain
  19. Recipient Count > Max RCPTTO
  20. MX Record check
  21. SFDB Filter
  22. SPF Filter
  23. MAPS check
  24. SFDC Filter
  25. Blank emails with attachments only
  26. Spam Images in PDFs
  27. Attachment Filter
  28. Keywords
  29. Image Filtering
  30. Bayesian Filtering
  31. SURBL check
  32. Resolve URLs and check IPs in MAPS

  1. Note - The Antivirus Plugin, if present, will stop any infected emails regardless of the whitelist settings

Please note the availability of the following option in the SpamFilter.ini file to handle exceptions with the first two blacklists that take priority over the whitelists:

;Add any IPs (separated by commas - no wildcards) that you do not wish to be automatically added to the Honeypot IP blacklist. This setting also prevents those IPs to be added to the IP cache blacklist, and to allow them to bypass the greylist filter
