When operating an SBS 2008 Exchange 2007 server should you have an A record  for the server, such as, remote.domain.com at IP address 111.222.333.444 and then an MX record using the same name, remote.domain.com?

Yes that would work fine.

You would also need to configure a rDNS record (your ISP will need to do this) and call that remote.domain.com as well

Thanks,  I was told only to use an MX record without an A record, but I wasn't sure how the MX record would work if it only had the name and not the ip address listed.  I figured an A record would be necessary so the name and ip address would match.  Is my thinking correct?

NO!

Using an MX record with anything other than an A record is in violation of the RFC setting out the way in which MX records should be configured.

Yes, you should create an A record and MX record. not only MX record.

Original question: >>"should you have an A record  for the server, such as, remote.domain.com at IP address 111.222.333.444 and then an MX record using the same name, remote.domain.com?"

My first response, "Yes that should be fine"

Thanks for the replies.  Not to kick a dead horse, but so I understand thoroughly.  

Should the entries look like:
Host name as @, Record type of A, then the IP Address or the mail server OR

Host Name as @, Record type of Cname, Address using remote.domain.com
Host name as remote, Record type of A, address as 111.222.333.444

MX reocrd pointed at remote.domain.com

Reading Step 2 in the document is confusing me a bit.  Should I use the ip address or the cname.

Thanks.

OK,

Record type A with a name of remote.domain.com pointing to the external IP

MX record = remote.domain.com

It's all explained in my article.

Sorry forgot to answer the question about CNAME, although I did in my previous posts.

an Mx record should use an A record, no other type of record is acceptable.

There is no need to setup a CNAME record.
