Website & Mail Question

Hi All,
I will not pretend to know a lot about this stuff, because I don't. So
with thatm if you need to explain something to me, consider me one of
those dummies.
Anyhow, I run my own mail server & web server. I own several domains
and they all point to my server.
A client of mine has asked me to run his website. So, he started by
pointing his domain to my server, and I am going to put up an "Under
Construction" page. When he does that, what happens to all his emails?
If his site is called abc123.com, and he points that to my server, does
that automatically route all his email (johndoe@abc123.com) to my
server also? Can one's server where the web site/domain exist be
different than the email server?
If yes, how does that happen? Remember please, I'm a dummy here.
Thanks.

We all started once - so no worries.

No. The reason is that for mail there is an MX record in the DNS
system. For the webserver there is an A record entry for the www host.
Those two entities are different in nature and alas there are TWO
entries, so each of them can point to different things.
The www record will point to the IP of your server or alternatively
will be a cname (alias) holding the name of your webserver.
The MX record will return the NAME of the server(s) which do mail for
abc123.com and hence can remain what they were for the moment.
If you start to do mail fro your customer also, he would have to
change the MX entry of his domain so as it point to your mailserver
-that's it.
