EUDORA SPAM FILTER 07
Keywords to Bypass the Remaining Filters

 

This filter allows any email containing my "secret"  keyword to go directly to the inbox and bypass the remaining filters  (my "gauntlet of torture"). The most logical key word for me to use is my name, "Cecil", since anyone legitimate who writes to me not only might know my name but may start off an email with "Hi Cecil" or similar. Instant access to my inbox, if so. Spammers? Those evil sleezeballs seem to think my name is "cecilw", just because that's my login ID. Don't call me "Hi Cecilw", or I will call you "SPAM". Other keywords can be added if needed for special cases.

 

 

Match: Incoming and Manual
Header «Body»
Verb: matches regexp (case insensitive)
Value: CECIL[^[:alnum:]]
Actions:   Skip Rest
 (stop filtering this message and go straight to the inbox)

The value "CECIL[^[:alnum:]]"  means find "Cecil" but only when it is NOT followed by a letter or a number.
("alnum"=alphanumeric, and must be typed in lower-case in this instance).

"Dear Cecil,"  works fine, as does "Hey Cecil!", or "Hi Cecil<sp>" or "Yo, Cecil<Cr-Lf>". "Dear Cecilw" fails miserably, to my great fortune.

I could have also used  "CECIL[^W]"meaning "(any Cecil, except not "CecilW"), but this allows in a few spams broadcast with multiple "cecilsomething"  usernames such as "cecilpeddle" (real example), if one of their names ends up in the body of the spam, as sometimes happens.


The morale of this story, if there is one, is don't use your first name as your email login!
