DNS

[hpuxsa]

We have two SMTP servers one is primary and the other is secondary. I need to configure the sendmail on all our HP servers so that if the primary SMTP server goes down we should be able to look at the secondary SMTP server. Could someone tell me how we can do this.

Is it possible to add an entry in dns with two ipaddresses against a hostname.

Hi

in your named configuration file, you must configure your dns-mx entry like that

ora.com. IN MX 0 ora.ora.com.
ora.com. IN MX 10 ruby.ora.com.

and then restart your named, 0 is the primary mx server and so ruby secondary,

What you do is, create a MX record to 2 different mail servers:

smtp1.yourdomain.com. 3600 IN MX 20 mailserver1.yourdomain.com.
smtp1.pcacorp.net. 3600 IN MX 10 mailserver2.yourdomain.com.

Then in your sendmail.cf file on your HP-UX servers:

DSsmtp1
