Can you elaborate? I'm curious to know why I would still receive emails.
If the mail server can't get your MX records, it won't know where to send it.

Many email servers will terminate the message when there is no MX record. Some will put it in a queue and keep trying for a specified set of days.
Due to the amount of spam around, most places don't use that outgoing queue like that.Show your reciprocal links on your website. eReferrer

thanks
related question, if a server acts as the dns server and it has A records to point a subdomain to another server, if the dns server goes down, will there be a cache so the subdomain will still resolve to server #2?
Is there a way to make that A record cache longer so I wont have a problem in the event server #1 goes down?
thanks again

Well it somewhat depends as well. If I sent you an email when you DNS server was down and it is not cached, a lot of servers will try a few times. For example I have ours set up to try again in 5 minutes, in 20 minutes and then in 60 minutes. If no response - then the email is returned to me telling me the server was not found etc.
So there is a chance that your customers would not know. This is why it is always good to have at least two DNS records on different Class Cs, different servers, etc. We even have a secondary DNS in another data center just in case.

I believe he is trying to figure out what could possibly happen to clients or whatnot if he potentially took down the plesk server? I could be wrong - i'm tired too.

The question is though, if my plesk server goes down and the plesk server is where the DNS server is with all the A records etc.
I want to know if I will still be able to access this sub-domain(pointed to this external server)
I thought that maybe the A records could be cached so it would not pose a problem.
If this is not possible, how does one setup such a configuration where the sub-domain would be accessable.
Is there some service i can use? How about those DNS companies? I heard some are free and good? any ideas.
thanks

This is usually why you have two DNS records set up. There is ZoneEdit, DNSMadeEasy for starters. Usually your datacenter will allow you to use their name servers as well.

If all you have is the one dedicated server, you need to look for a secondary DNS supplier, who can slave your zones.
