## STAGE 2 - FILTERING SPAM EMAIL
## choose one of option 2.1, 2.2, 2.3 or write your own
## option 2.1 enabled (uncommented) by default

## option 2.1: configure your client to filter spam; all fall through
##   you need to configure your email client to filter based on one of
##   the following headers:
##     X-Spam-Flag: YES
##     X-Spam-Status: Yes, hits=[\d+\.\d+] required=[\d+\.\d+]
##       where [\d+\.\d+] matches floating point numbers (e.g., 13.1 or 4.7)
##     X-Spam-Level: *******
##       where the number of asterisks equals the number of hit points
##       (e.g., 13 asterisks for values between 13.1 and 13.9)
## no procmail recipe associated with this option so nothing to uncomment

## option 2.2: delete spam with 15 points or more; rest fall through
#:0
#* ^X-Spam-Level: \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*
#/dev/null

## option 2.3: delete all spam (warning: false positives also deleted)
#:0
#* ^X-Spam-Flag: YES
#/dev/null
