[Exim] Exim Wish List

Here's a few items I'd like to see added/changed in the next version of
Exim.

lookup dnsdb
---------------

Should also include the ability to look up soa records.
Should have a switch or option that if the lookup fails - that it return
an empty string or something settable like "NONE".

Would like the ability to write/change headers from filters other than
the system filter.
Would like to have a header replace command so I don't have to do a
delete and add.

Isn't to time to upgrade your Mailman version to the latest? This list
is running on an acient version.

My 2 cents ....
