Need help directing ReadyHosting.com email to new SBS 2003 Exchange Server

I've been trying to figure out how to get this done now for over two weeks and I can't seem to get it done. I thought I had enough information after posting a previous question at:

http://www.experts-exchange.com/Web/Web_Servers/Q_21150423.html

Unfortunately, I was aimed in the right direction, but have since lost any forward momentum toward a solution. ReadyHosting.com is currently our public email host and we have put a new SBS 2003 Exchange Server online. We are trying to get the public email integrated into our local server and ReadyHosting.com is asking me the following:

"If you would like to request changes to this domain's dns file you will need to tell me what those changes are.
Please specify what dns record you would like changed and what you would like it changed to.
Please send those requests to dns@readyhosting.com"

My problem is I don't know what exactly I'm supposed to specify or how to format the request for the necessary changes. I know from Q_21150423 that I need to modify DNS and MX records, and I would...if I only had a brain.

I tried SBS 2003 MS Connector for POP3, which worked great after I figured out ReadyHosting.com doesn't support SPA, but I can't allow the use of clear text credentials. They suggested that, "If that is something that you have to use, you will want to use your isp's smtp settings instead of ours." We have SBC Business DSL, but that's about all I know about that and need more information to understand if this suggestion is even an option. Does this mean I would have to register mydomain.com with SBC instead of ReadyHosting.com?

I have configured Recipient Policies on the Exchange Server for me@mydomain.com as well as internal mail to me@mydomain.local, but no public email makes it to the SBS 2003 Exchange.

DNS direct is better than MS Connector for POP3 from what I can tell. However, if I had SPA support from my email host, I already know I can pull that rabbit out of the hat. Right now, all I have is a head ache!

I could really use a hand...

Thanks in advance,

Brian

Here is a nslookup (names/IP address changed to protect the guilty) from mydomain.com:

nslookup
> set q=mx
> mydomain.com
Server:  UnKnown
Address:  192.168.0.1

mydomain.com    MX preference = 10, mail exchanger = mail.mydomain.com
mydomain.com    nameserver = ns7.readyhosting.com
mydomain.com    nameserver = ns8.readyhosting.com
mail.mydomain.com       internet address = 63.63.63.64
ns7.readyhosting.com    internet address = 63.63.63.65
ns8.readyhosting.com    internet address = 63.63.63.66
>

How would my nameserver and MX Record(?) be different if my SBS 2003 Exchange Server is mydomain.local with a public SBC "sticky" IP of 64.64.64.65?

I don't think I'm even asking the right questions!

Here is nslookup from SBS 2003:

C:\>nslookup
Default Server:  mysvr1.mydomain.local
Address:  192.168.32.2

> set q=MX
> mydomain.local
Server:  mysvr1.mydomain.local
Address:  192.168.32.2

mydomain.local
        primary name server = mysvr1.mydomain.local
        responsible mail addr = hostmaster
        serial  = 121
        refresh = 900 (15 mins)
        retry   = 600 (10 mins)
        expire  = 86400 (1 day)
        default TTL = 3600 (1 hour)

Is this what ReadyHosting meant by using my ISP's smtp?:

Your host is asking you to use your ISPs SMTP Server. This is a common request from a web host. However Exchange is quite capable of delivering email messages itself, but if you have problems then you would use an SMTP Connector to route email via the ISPs SMTP Server - a SMART HOST in Exchange speak. That article tells you how, but if you want a second opinion then look here: http://www.amset.info/exchange/smtp-connector.asp

To ensure that you don't get incorrect DNS results you should use external DNS services to verify. dnsstuff.com is a good place to start.
The only thing you need to change is this line:

mail.mydomain.com       internet address = 63.63.63.64

The IP address needs to be changed to your static IP address from your ISP.
If the IP address isn't truely static then you should look at getting a dynamic DNS address. This will ensure that your email continues to work even if the IP address changes.

Name server information should stay the same.

First, Thanks!

Let me make sure I understand exactly what I need to do next...

   Send an email to dns@readyhosting.com with the following request (names/IP address changed to protect the guilty):

   Please make changes to mydomain.com domain's DNS, A Record, and MX files accordingly:

   FROM

   mail.mydomain.com       internet address = 63.63.63.64

   TO

   mail.mydomain.com       internet address = 64.64.64.65


Would this be the correct format and syntax (I'll use the actual names/IP address of course)?

Are there any other configurations necessary at my end?

Once these change are made at readyhosting.com for mydomain.com:
      A. Will all existing mail stored at readyhosting.com for mydomain.com be sent to my SBS 2003 Exchange Server?
      B. Then be deleted from the readyhosting.com mail server?
      C. Send all subsequent email to my SBS 2003 Exchange Server and No longer store any email for mydomain.com on the readyhosting.com mail server?


Best regards,
Brian

You have the correct information to give to the host.

Bear in mind that it can take up to 48 hours for DNS changes to propagate. Therefore whatever solution you using for receiving email needs to be left in place for at least that period (I would leave it in for another 24 hours after the 48) to collect any emails using the old information.
I don't know the host, but I would be very surprsied if they will send you email from their servers using the new settings, so you will have to collect it from them. It probably already deletes it, but you may need to check.

Once the changes have propagated then all email will come to your own server and not go to hosting company.

Thanks for your help - won't be needing my Prozac today!

I will be submitting the request for DNS changes based on the information above. In the event I am asked for additional information from ReadyHosting.com, I hope I can ask a follow up question or two.  I'm still fuzzy on MX and A Records and expect that the web host will know what to do with them and I won't have to do anything further on my Exchange Server.
