How can Exchange work on SBS without DNS records?

by olioliumphry . Updated 18 years, 2 months ago

If I sound a little uneducated, well….it’s because I am.

I inherited a server running Windows SBS with all the typical roles setup including DC, RRAS, IIS, DNS and Exchange. The company I’m working for is changing their ISP which is going to give us a new IP address so I need to point DNS records to this new IP address.

The problem is….when I open the Forward Lookup Zone in their DNS I see no records for any mail routing(A or MX), and there are no POP3 or SMTP connectors configured in exchange.
I did notice that there was a CNAME record called “companyweb” pointing to servername.domain.local. Don’t know if this is relevant but thought I should mention it.

I called the previous IT company and they told me that the mail is routed through a 3rd party spam provider called MXLogic.

Could someone explain to me how this works, or am I simply missing something? The IT service comapny offered only what I’ve stated. Nothing more.

Is the mail being routed to MXLogic’s server and their pushing it to me? If so, shouldn’t there be some routing between us?

Remote Web Workplace and Webmail is also setup and working.

Thank you in advance
