When to lock?

Hi there,

I have some typical recipies that I have been using and I would like to
get some input on efficiency.  When is it appropriate to use a lockfile
and how are locks best implemented in procmail recipies?  I thank you for
your opinions.


# typical spam marker

# overly exited people

# too many dots

* ^Subject:.*\.\.\.\.+
${SPAM}

# from differs from recieved

   | formail -I"Subject: [unmatched from] ${MATCH}"
   * ^Received:[        ]from[  ]\/[a-z,A-Z,0-9,\.,-,_]+
   | formail -I"Subject: Spam from ${MATCH}"
