I received the following email today from Covad - our access provider.
It looks like they have a problem with Declude checking inbound emails
against a realtime blackhole list. (The problem could also be several
emails we've received lately with hundreds of recipients, many of which

There could be many RBL's in your config (we have about 100 in ours...which
we probably need to prune since many don't add any real value), each of
which would require a DNS hit for each message.

Kevin, you're probably using your ISP's DNS servers to do the RBL
lookups for you. Either your operating system is configured with

What you need to do is set up a DNS server on your IMail server and
point IMail to query that server instead of the one operated by Covad.
The performance of your machine will also likely

Hi:

queries to certain RBL's.
And rightfully so - ISP are offering domain name resolution service to

resolution, even though they use the public DNS to store
You probably want to take this in baby steps. Let's start with - are
you sure that you're not already running a DNS server on your
mailserver? Then you can go on with using Add/Remove to add the DNS
server.
To avoid any issue with your mailserver needing DNS records at all, just
change your
