EUDORA SPAM FILTER 05
Email Newsletter Subscriptions

 

This filter (and as many more like it as needed) checks the subject line to see if it contains the words I've specified and in the order I listed them. This example is an email newsletter from Microsoft that I got suckered into subcribing to. This filter only works if the portion of the newsletter name that is checked does not change from issue to issue. For example, it would find "Inside Office Newsletter for the Month of February", but it would NOT find "Inside Office February Newsletter".

 Filter Image Date 7/08/03

 

Match: Incoming and Manual
Header Subject:
Verb: contains
Value: Inside Office Newsletter
 
(change to the name of your newsletters)
Actions:   Skip Rest
 (stop filtering this message and go straight to the inbox)

 

The "Contains" action is not case sensitive, so it would find "inside office newsletter" and "Inside Office Newsletter" equally well.

This filter could also be set up to search for two different email newsletters by using the "or" function, or for multiple newsletters by using the regexp (case insensitive) verb and the "|" (or) symbol.
