Fair enough. I never considered that.

I think that we are talking about 2 different things. Or at least I 
misunderstood what you were talking about.

I was thinking from your description,

From: would be selectable to keep or strip
Subject: would be selectable to keep or strip
To: would be selectable to keep or strip
Cc: would be selectable to keep or strip
Date: would be selectable to keep or strip

etc. as SEPARATE individual choices to. Not as a group. Now that I 
understand your thinking, I think that this may be a very viable 
alternative. Maybe even less of a support issue.

Maybe both what you are thinking and the RegEx would work well 
together. The keep/strip for those that want simple and RegEx for 
those that want the extra control.

Neither do I. Unfortunately I'm just learning Python, so I don't know 
who hard or how easy any of these suggestions are.

I can see that. I'm, personally, not convinced, but then I haven't 
been a mail admin as long as you have been.

I'm not worried about all the nuances involved. I was just trying to 
get what we, you and I were discussing, sorted out. And now I realize 
that we weren't quite talking about the same things. I was talking 
about controling individual headers, separately, and you are talking 
about controlling the "basic" headers as a group.

Whose idea is better? Not my call, I'm glad to say. I guess we just 
need to wait and see what Barry has in store for us :)
