Exim Flitering question

[coffeekid]

I currently have to write an exim filter that would do the following:

1) Allow any email to postmaster.

2) Deny all email to local users from any postmaster.

3) Route all bounced messages to postmaster.

I've never done any incoming mail server work, so this is a bit perplexing to me. I've googled this a few times and had no luck in these options specifically.

I do have the config files and the location in the config files where this should be implemented. Here's what i have (it may not be even close).

[adaptr]

1) is set by default.
2) is tricky; the way you write it may cause local postmaster replies to be discarded!
3) is the big one, obviously - if you're not careful you may end up being bombarded by spam and the like.

No specific help from me, alas but the Exim specification is quite elaborate...
