SIMS has a single primary domain name which is set in the general 
settings, and is usually a real hostname that resolves to the primary 
IP address of the machine SIMS is running on. All other domains are 
handled by mapping addresses in them to the main domain in some way. 
The simplest method in the router is this:

secondary.domain = main.domain

That means that all mail aimed at [EMAIL PROTECTED] is delivered 
to the local mailbox of "user" which is also where all mail for 
[EMAIL PROTECTED] would land. In order to split up local mailbox names 
by domain so that [EMAIL PROTECTED] and [EMAIL PROTECTED] messages 
deliver to different  local mailboxes, you need to map the addresses 
for secondary domains a bit differently in the router:

<*@secondary.domain> = *.secondary

then the person being mailed as [EMAIL PROTECTED] would use the 
account name 'user.secondary' to log into the SIMS POP3 server to 
pick up mail. Note that you can do that mapping differently if you 
prefer, so that this line:

<*@secondary.domain> = secondary-*

would also work, and mean that mail aimed at [EMAIL PROTECTED] 
would deliver to the POP3 account 'secondary-user'.

It is mostly automatic:

1. Make sure your DNS is correctly listing the primary as an MX 
record with a lower value. A properly configured secondary should be 
holding mail and retrying the lower-metric MX record(s) regularly for 
delivery.

2. If you run SIMS on the secondary, add a line like this to the router:

domain.com = domain.com.smtp

That assures that the secondary will understand that it is a 
secondary for that domain and won't bounce messages aimed at 
domain.com. Most modern MTA's with anti-spam relay controls will need 
some similar setting.
