All,

What is the best way to achieve s/// functionality in Maildrop filter files? Reading the docs, all I see is that I can pattern match using the ! (supposedly processor-intensive? is there a better way?), and then reconstruct the string I desire using the $MATCH variables. It'd be nice if there was a simple substitution operator, but if not, can anyone point me to some quickie examples of how to do this "The Maildrop way"?

TIA!!
