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 [EMAIL PROTECTED] x
16 [EMAIL PROTECTED] 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....
