If i have a DNS services installed on the same server as my mail server, and remove DNS, can i still access my mail server?

I should right, if i have the proper associated MX records?

Define "remove DNS".

Do you mean that you will move your DNS to another server?

The MX records are served by the DNS server. No DNS = no MX = no email.

Ok, let me rephrase...

What if i remove an A record that is creating some DNS issues?

There is an A record on that server that is making some ISP's show an old website....

I have a new site with new name servers on a differnet host, that depending on where you are, will show the new web site....

Assuming that the A record is not for the mail server, it has no impact on mail.

The mail server, of course, needs an A record as well as an MX record. If the mail server is in some other domain, of course, the A record is supplied by that domain's DNS server.

It would probably be useful to give some details, using "example.com".

Well, i have come to find what the issue is.

i had example.com on a mac mini in south carolina. it had web, intranet, mail, dns....etc.

i created a new site with a hosting company.

i logged into go daddy and changed the dns records to point to my new dns server, with the hosting company.

somehow, some top level domain servers kept the old IP address in their records, along with my new domain servers..

so in essence, there are top level domain servers dishing out dns records to my old and new site....

so its a good old crap shoot to see what site you get....
