We use Win2003 Server with MS DNS. Fairly new to DNS and can't seem to figure this out.
We have a client who has an A record pointed at an IP with a 3rd party service. Now they want to be able to send & receive email via email@example.com using our service.
Currently his domain has a mx record pointing at our mail server and I want to know if I can set it up so that the will work through our service.
I have copied the record in here and changed the names etc to hopefully get some insight
Zone records - domain.com ;
@ A 111.222.333.444
@ MX 10 mail.emailhost.com.
abc A 999.888.777.666
www A 111.222.333.444
So the 3rd party is abc.domain.com and everything else is hosted through us. He wants to know if he can have us setup email firstname.lastname@example.org and run it through our service at mail.emailhost.com.
