If the delivering MTA supports it then two MX entries in your DNS with the same priority will cause the MTA to randomly pick a mail exchanger. What were you hoping to accomplish by load balancing rather than upgrading your primary MX and having a backup MX?

cheers

Hello jamie,

I'm tryin' to balance the mail requests that come at a server. The cluster is not visible to the end user. He sees only a single virtual server, which has any load-balancing algorithm runnin' on it.

Regards,
Deepa

I'm not sure wether http://www.linuxvirtualserver.org will have any useful info for you. Exactly which MX gets used is invisable to the end user anyway, they just send mail to user@domain.net and its gets there. You didn't answer the question about why you were going for a load balanced system instead of upgrading your primary MX?


cheers

I'm not using the Internet. I'm balancing the load in my LAN conn. So, there is no question of MX records. I think i've gone throu' the linuxvirtualserver site. But, i didn't find it useful.
I wanted to know how to go about it ?

Regards,
Deepa

If you don't have any MX records in your DNS then you won't be able to email user@domain.net you'll have to directly use a mail server so user@mailServer.domain.net. If the virtual server site did hold any clues then I'm not sure what to suggest. As mentioned earlier there's not normally a need to load balance an SMTP relay. I take it that you are talking about an incomming mail server rather than a mail server that your users *collect* their mail from.

cheers
