[thelist] list manager (broadcast only) recommendations

[bruce at brucelawson.co.uk]

Hi list,
my boss wants to be able to send approx 200,000 html mails/ week reliably
with unsubscribe facility, automatic deletion from the database of garbage
email addresses, and automatic retry of temporarily bouncing addresses.
These are broadcast newsletters rather than discussion lists. Lyris is way
too expensive, so does anyone have any other recommendations?
We're running Windows servers, SQL Server 2K database. Ease of set-up and
reliability are the most important criteria.

Thanks!
