Thanks Wili for the advice,
For the DNS I had already put both Mx1 and MX2 on A record. So what is the CNAME for on this case? please another advice.
For the second option how is the failover works on local LAN? Seems I have to build the backup mailserver exactly the same wit the main server including the account and milist on it.
 
Thank you.

You can set backup MX in DNS Server. If you had MX or MX1, you can set MX2 in DNS server with another A record. And add CNAME record for new MX.
I had the same problem before.. and I tried that way. It's work !!
But it's depend DNS Query from DNS Server.. be patience, need a time for refresh it.
There so many way to backup your mail server. Such as....
You can using 2 NIC in your server. eth0 and eth1
eth0 you can set IP for internet, and eth1 you can set for LAN with backup server.
In backup server you also using 2 NIC too, eth0 to internet and eth1 to LAN to server mail.
It's semi manual backup but you don't use internet bandwithd for backup you mail server. Just using LAN conenction for fetchmail.
example :
Server Mail
eth0 : 202.34.23.5
eth1 : 192.168.1.4
 
Backup Server Mail
eth0 : blank / another IP (Use itu for 202.34.23.5 if primary server it's trouble)
eth1 : 192.168.1.5
 
Ok... that all,

Subject: [qmailtoaster] Back UP MX

Hi all,

I am using my qmailtoaster mostly as mailing list server. My question, is there anyway to have a back up mx that will continue to send/distribute the emails to the list whenever the main server down.

Currently I have one primary mail server  and one backup mail server with setting mx on DNS are 10 for the backup. But seems the backup server never take over the primary to distribute the email while the main down.

Is there anyway that I have to setup to make it works? Your help would be great full and appreciated.

 

Thanks
