Hi everyone

So far i managed to create a secondary MX record to the mail backup server

with a pref. of 20

My question is:

Do I need any changes on my exchange server or do i let my IPS do their magic?

I was thinking: How does my exchange server know where to look for the mail?

Regards

Kenneth

SMTP is a push protocol. SMTP servers don't go looking for mail. Any SMTP

server with mail for your domain looks up the MX record and attempts to

connect to the server with the lowest preference value.

You don't have to do anything internally, in most cases you don't even need

MX record internally at all, all it is needed ( internal mail routing) is

simple A record for the mail server which gets added dynamically to

internal DNS servers.

Your ISP will include the second MX record into Public DNS servers, where

people from outside who wish to sent mail to your SMTP domain, will perform

MX queries to locate your mail servers , the lowest MX record Priority gets

the most attention, but in reality it is up to sender who to send the mail

too (-:

I don't want to confuse you but ISP DNS servers will have MX records in

their public DNS servers and tell people who are trying to locate your mail

server here is MX record (10) mailserver1.yourDomain.com and MX record

(20) mailserver2.yourDoamin.com, now I am given answer to my MX query

question and I was told to try to use mailserver1 (first) if there is no

answer, I am told to use mailserver2, but in reality if I don't like to be

told things (-: , I can sent mail to whom ever I want and this is what

spammers do (-:

Cheers

To add to the other replies - whomever you're directing mail to with that

2ndary record should configure their server to queue/spool mail ...

automatically retry delivery to the server specified at a lower cost /

higher priority, for several days.
