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@the.backed-up.domain.tld x 16 user2@the.backed-up.domain.tld 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.... -- David C.
