To get an idea of what I'm talking about, have you looked at the per-mailbox filtering in Horde? This is a point and click front end to regular expressions, which let you specify whether a subject, To, From or Contents of e-mails contain, or begin with words or letters. So, for example, anything Subject "Rolex" or "******" or "beginning with Vi". The reason I wrote my own program is because the filter front-end in Horde is not sophisticated enough. You might want to look there first.
My previous ISP had a similar front end on a per mailbox basis for users to configure. I ended up configuring it for my users, but it was point and click.
I'm happy to help where I can, but as far as my scripts are concerned, I think that if you aren't a PHP programmer you might find what I have to offer a bit hard to use. This is a fairly blunt tool for my personal testing and use, I don't rely on display or saving a list of deleted headers. My logic is a bit skewey as well, because I am not careful to avoid repeating the filtering.
I sent the following as a private message to eukhost.com last night, suggesting that some of the support staff might be able to refine these for you. Here, below are three functions. A button in an HTML form executes the function named "filterMailbox".
I use the regular expression tester here: www. quanetic.com/regex.php
Try the Horde filters and if this seems right to you, let me know and I'll include you in any developments I manage with exim.

Not sure if your method will address my problem, but at this stage I am willing to try anything!!! However I'm far from a linux expert... so be gentle
