Subject: SIMS dual domains

Hi all,

Still running SIMS here despite all rumors to the contrary.

I need to run dual domains on SIMS as the organization is moving to a new
domain name. We want mail sent to or
to both go to the same user mailbox.

My checklist is as follows:

Turn down TTL's on existing domain.
Establish new domain with A, and MX records pointing to SIMS.

Give SIMS it's new domain name:
Set up a routing entry: *

Set up CNAME on old domain name record: CNAME
Remove A record for
MX record on old domain points to

Then sit back and watch the mail get delivered.

I don't recall the best way to set up the router entry as it's been awhile
since I tried this. Any tips on this checklist or the correct router syntax
