[exim] if $message_size && user ==

Here spams over 200K get the red carpet treatment,
procmail:
driver = localuser
transport = procmail_pipe
require_files = ${home}/.procmailrc
condition = ${if < {$message_size}{200K}{yes}{no}}
Keeps the machine load down, but dialup users can't swallow the result.
How can one add "or the user is on the list of responsible users",
or "or $user == responsible_ralph", to the condition? Just reading
spec.html I would surely screw up, hence I ask here.
