       There are some special conditions you can use that are not
       straight regular expressions.  To select them, the  condi­
       tion must start with:

       [...]

       $    Evaluate the remainder of this condition according to
            sh(1) substitution rules inside double  quotes,  skip
            leading whitespace, then reparse it.

Therefore,

NAME=leandro
:0
* $ name=$NAME
/dev/null

This is assuming you're looking for the string "name=leandro" in the
headers. If you're looking in the body, the recipe will need a "B" flag
or the conditon would need to read: * $ B ?? name=$NAME.

Reply to list please, or append "8" to "procmail" in address if you must.
Spammers' unrelenting address harvesting forces me to this...reluctantly.
