asked on 

A Record, MX Record, OWA

I need some assistance here with a few items.

I have a hosted account with Network Solutions that allows me to modify A, MX, SRV, Cname records.

This is what I want to do.
Point hosted website named abc.org to hosted shared website folders. This is done and working.

Point my mail records using MX and A record to public IP address that is pointing to my web filter. This is working because we are getting mail and it shows up on the filter.

Point my OWA site to a seperate IP address that points to my mail server.

The problem I have is they are the same name. Example mail-1.abc.org
So when I setup the A record for IP address 1 (filter) and A record for IP address 2 (OWA) they have the same name (mail-1)
It seems to me that some mail is getting directly through to the mail server because some spam is no longer being blocked and I dont see any record of it on the mail filter. I believe this is because of using the same name in the A record.

Is there any way to us a Cname record to point the OWA site to the specific IP?
The reason I want to keep the same name is because I dont want to change all of the users cell phone settings and have to try and teah the users the new web addresss.

Any help would be greatly appreciated.

You should have an A record pointing to your www, another one pointing at mail-1, and the MX pointing at your spam filtering company. Your spam filtering company should be configured to relay good email to the mail-1 A record.

You should not need the A record that is pointing to your spam filtering company. If you do for management reasons (if you own the device) you should name it something else.

ThorinO,
I thought the same thing about not needing the A Record for the mail filter. But what is funny is when I created the MX record the A record was created automatically.

achaldave,
Would you concur that I dont need the A Record for the mail filter?

No, you need A record for mail filter, when you create mx record say smtp1.abc.com the smtp1.abc.com requires A record to resove to correct IP address

I hvae deleted the A Record to the mail filter.
I have deleted the MX Record.

I have created a new MX Record of smtp-1.abc.org and in turn it created the same record in A Records

I will let you know how this turns out once it propagates.

achaldave is correct, there needs to be a matching A record. Is this client in production? Does your spam filter company send mail to your IP or that old mail-1 A record, if the A record that should be updated with the new smtp-1 record when available.

This exchange server and website is in production. I manage them all.
Everything on the spam filter (hardware barracuda) uses mail-1 or internal ip address. Nothing seems to point to the external ip address. I believe the firewall directs traffic before hitting the spam filter.

Does anything need to be changed on Exchange box to match smtp-1 or does this name really not matter?

Nothing needs to be changed on exchange server when you change the MX record.

Also I am not sure if your firewall can do that or not but if all inbound traffic is managed by firewall you can try configuring your firewall to redirect all incoming trafic for port 25 (default SMTP )  to your spam filter.
