Sandy, list:

   I have 2 situation where I need to configure a backup for our mail 
server:

(1) I want to configure the remote site 3111skyline.com to accept mail as a 
backup to rbpllc.com, rankinlawfirm.com, and guillorylaw.com.

I have read http://www.postfix.org/STANDARD_CONFIGURATION_README.html#backup

and I have entered the MX record of:

rbpllc.com    IN MX    50    3111skyline.com

In the DNS of the domain provider for rbpllc.com

I have made the following recommended changes and done the appropriate 
postconf and reload:

4 /etc/postfix/main.cf:
5     relay_domains = . . . the.backed-up.domain.tld
6     smtpd_recipient_restrictions =
7         permit_mynetworks reject_unauth_destination
8
9     # You must specify your NAT/proxy external address.
10     #proxy_interfaces = 1.2.3.4
11
12     relay_recipient_maps = hash:/etc/postfix/relay_recipients
13
14 /etc/postfix/relay_recipients:
15     user1@xxxxxxxxxxxxxxxxxxxxxxxx   x
16     user2@xxxxxxxxxxxxxxxxxxxxxxxx   x
17      . . .

Is this really all there is to it???

(2) Inside the LAN of rbpllc.com, I want to designate the server 
'providence' as the backup mail server to the primary server 'bonza'. Bonza 
runs DNS as master and providence runs DNS as a slave server for the zone 
rbpllc.com. What do I need to do other than adding a DNS MX entry to the 
zone for providence to provide this backup capability??

Sandy, your wisdom will be very welcomed, as always....
