How to change DEFAULT in the procmailrc?

O


 Hi, all
 There are environment variables in the procmail.
 the variable DEFAULT is the mailbox file.
 I want to know  how to change dynamically DEFAULT variable  
 in the procmailrc or other.

 I already know the static assignment of the enviroment variable
 like following.


  DEFAULT=$MAILDIR/$LOGNAME


  bye
