EUDORA SPAM FILTER 21
HTTP X 3
 

Catches: Email containing 3 or more HTTP links

People who don't know me don't often send me email containing three or more HTTP links, but spammers regularly do. This filter may result in a few extra false positives however so pay attention if you use it.
 

 

Match: Incoming and Manual
Header «Body»
Verb: regexp (case insensitive)
Value: (HTTPS?:.*){3}
Actions: Transfer To Spam.mbx
   Make Label 7
  Make Priority Lowest
  Skip Rest


NOTE*
- Correction to my previous expression here: "(HTTP){3}" would look for "HTTPHTTPHTTP" - not what we want at all. Use "(HTTP:.*){3}" instead. The added colon ":"is desireable because not all references to "http" in the message body relate to http links. And now I"ve decided to ad an optional "S" (S?) since a few spam do contain "https:" secure links.
