Re: Filtering on the cc line size

Philip Guenther suggested to wotan(_at_)netcom(_dot_)com, who had asked:

| 
| :0
| * ^Cc: \/.*
| * MATCH ?? > 200
| /dev/null
| 
| 
| BUT:

| from the HISTORY file:
| 
| 1995/10/29: v3.11pre4
|             Changes to procmail:
|                - varname ?? < nnn conditions didn't have the expected effect
| 
| So that might not work if you have an older version.

This will work with some older versions (if they are stil new enough to have
the variable ?? syntax at all):

  :0
  * ^Cc:\/.*
  { 
    PERMITTED_LENGTH=some_limit_you_set

    :0
    * 1^1 MATCH ?? .
    * $ -$PERMITTED_LENGTH^0
    /dev/null
  }

Personally I would do it not by the number of characters but by the number of
addresses in the Cc: header:

  :0
  * ^Cc:\/.*
  { 
    PERMITTED_COUNT=some_limit_you_set

    :0 # note the comma instead of a period
    * 1^1 MATCH ?? ,
    * $ -$PERMITTED_COUNT^0
    /dev/null
  }
