RE: E-mail Problems

Once I added Reliatek.com to my host entries, I can now send mail to
Justin@reliatek.com. But I am going to setup mail.reliatek.com.

                      Work with TCP/IP Host Table Entries

                                                             System:
RTEK
 Type options, press Enter.

   1=Add   2=Change   4=Remove   5=Display   7=Rename



      Internet         Host

 Opt  Address          Name



      127.0.0.1        LOOPBACK

                       LOCALHOST

      192.168.0.6      reliatek.com      <------------added this

                       www.reliatek.com

Justin,

        Al this magic is in the Domain Name Server(s) setup for your
site
!!!  A URL is a host name as well as a test string for the HTML Server
to
parse.  What you need to know is how the MX & A records are setup for
the
domain, what order they are in, and how they resolve.

        Remember that a host name is nothing more than a symbolic
representation for the IP Address of your system. Then once the packet
is on
the system different processes monitor the different services / ports
and
take over to resolve things. So if  www.reliatek.com  resolves to
172.16.200.10 and it's a HTML URL than port 80 or 443 might grab it, if
it's
mail then port 25 might grab it, if it's telnet then port 22 ect...

        Now where the magic comes in is when you want all the mail for
reliatek.com regardless of the hosts supported to be routed to a single
system. To do this in the DNS you provide an MX for the mail server at
the
zone level and then your individual servers below it.

        For even more magic, if you have an internal private network,
you
need both a public DNS and a Private DNS, and again the zone records
need to
be setup for the DNS to route all the domain mail to the correct
server..

        This is not beginners stuff, have fun !!

        JMS..
