Calling programs from procmail most efectively?

    Hi,

    I just realised that the backticks always trigger procmail to
    feed the whole message to te called shell, right? So in fact
    the statement above is not the best one:

        dummy = `echo "$FROM $SUBJECT" >> $SIMPLE_LOG`

    but instead I should write

        :0 hi:
        | echo "$FROM $SUBJECT" >> $SIMPLE_LOG 

    but it's not one liner any more and breaks the A E dependencies
    in my .procmailrc. Can someone comment if using the first one
    is that expensive that I should care about it?
