If you can optimize those regexes, it can only help. But also make sure
you're not looking at anything but the *headers*, because you neither
want to parse the message body looking for headers, nor do you want to
treat something that looks like a From: header like a header if it's in
the message body.

So if you cut back on the data you regex against, that's probably going
to help as much, if not more than anything else, because the headers are
probably a relatively small percentage of your data.
