OK, forgive my ignorance, but I'm trying to add a Spam Filter rule that allows postings from a specific e-mail address -- as an exception to our normal filtering rules.

It hasn't worked thus far, so what would be the proper (best) 'Spam Filter Regexp' entry to accept any messages from this example address:

some.person.name@gmail.com

I know this should be easy and that I'm just missing something silly, so any quick help would be appreciated.

Are you just trying to avoid trapping mail from some.person.name@gmail.com in other header_filter_rules? You can do that, but first, here are some things you can't do with header_filter_rules.

You can't bypass holds for bounce_matching_headers.

You can't bypass membership and moderation checks.

You can't bypass other holds such as message too big, etc.

This is because the Accept action on a header_filter_rules rule only means pass the header_filter_rules tests. It doesn't mean unconditionally accept the message.

So assuming that what you want is to bypass the other header_filter_rules, you need to "add new item" before the current rule 1 so the new rule becomes #1. Then the new rule 1 regexp should be

^from:.*(\s|<)some.person.name@gmail.com(\s|>|$)

and the action Accept.
