SBS 2003 mail best method 1

Whoever is maintaining your Internet domain DNS needs to update the MX record to point to your IP. This works like this:

An "A" record is created that points to your Public IP address. I usually use "office", as in "office.domain.com". NOTE: The RFC for SMTP email says it HAS to be an "A" record and NOT a "CNAME".

Your ISP creates a reverse DNS entry for your Public IP address. Just ask them them to do it, and tell them your domain name.

Once those records are in place (and correct), then the MX record is changed to point to "office.domain.com".

Once that happens, you should start to see email come into your server.

58Sniper, you are a star. You hust have helped me out 3 or 4 times over the last year.

Can I just make sure I am clear what I am to do.

Our domain name is company1.com so E-mails are fred@company1.com
The SBS servers domain name is company1admin.co.uk
Will this coause a problem?

If not, will my ISP just create the reverse DNS for company1.com or company1admin.co.uk?

Or am I missing something.

No, it won't cause a problem. The internal AD domain name has nothing to do with the smtp domain name. Tell the ISP you need it for company1.com.

Make sure that your Recipient Policy in Exchange is configured for company1.com email addresses, and you're ready to have the MX record changed.
