MX Records and Two mailservers

[Guest]

Hello,

Joe here, I just spent about 2 hours confusing the heck out of myself
here.Maybe another brain can bail me out?

I have two mail servers and one is also a webserver So one has IIS and Mail.
The other is strictly a mail server and the main mail server.
This main mail server has an MX of 10 and the backup 20 and are identical on
the DNS

MX:maydomain1.com
MX:mydomain2.com

The problem I am having is if I send mail out of the second mail server
(first mailserver is fine) that has the MX priority of 20 not 10 I cannot
send mail to any of my domains at the primary mailserver. BUT I can send to
Hotmail and other domains.

What am i Missing here?

Thanks very much
Joe

I'm assuming you are not using Exchange, because you implied that the
"other" mail server doesn't have IIS installed, which Exchange 2000 & 2003
requires.

I'm also assuming that the two mail servers don't host the same domains and
they are not in the same "organization", as it's called in Exchange.

If this were Exchange, I would suggest to create an smtp connector to the
"other" server with those specific address spaces for those domains the
'other; is handling.

Another possibility is to use only your internal DNS, which assumingly your
mail server is resolving the MX records using an outside DNS. I would then
force a specific domain's MX to the specific server hosting it, instead of
the way it's setup for the public.

Maybe someone else can come up with something else.

Hello Ace,

Well You are correct.The mail servers are not Exchange.
Yes they have the same domains on them. So if the main server is down the
other can pick up the mail. Both servers are internally networked so there is
a connection. actually the IIS server sends out of the main server. So... in
the interim I may have thought something up.

It appeares to be redunduncy.
Example:
MainMail server:
MX Mydomain1.com
MXMydomain2.com
would have two MX records
Back up only one MX which is the main servers IP

Now the MX on the backup would have only one MX
MXMydomain1.com

so when i send out it would use the first mailserver and if that server were
down then it would be sorted to the backup.
Sound right? or just jibberish he He
Thanks for all your help lets see what happens

Sounds so complicated! LOL. I'm not sure how your mail server works.
Exchange would know where the mailbox exists in the organization and just
routes mail internally to each other.

You can try that solution. Let me know if it works. I guess there's no way
to make the MX records equal priority?

Hey Ace I got it! LOL what an idioit I am ha Ha

The mailservers if they have the domain on themselves they deliver internally.

So the mailserver that had IIS was not reading the MX for itself but it had
to for hotmail and aol etc...

In the interface there is a selection to deliver mail externally. And whala!

Ha not complicated just me

Thanks for your time

LOL!

I thought the thing would know not to send outside when it's looking for an
internal recipient in it's org, whether on the server or on another server.

Glad you figured it out!
