Dear fellow users,
I have a few questions I hope someone can shed some light upon.
My current setup:
486DX, 24 MB of RAM, Red Hat 6.1 [gateway]
486DX, 20 MB of RAM, Slackware 7.0 [primary dns]
386SX, 8 MB of RAM, Slackware 7.0 [secondary dns]
486DX, 16 MB of RAM, Slackware 7.0 [dhcp server]
P66, 36 MB of RAM, FreeBSD [mail server (*)]
P133, 32 MB of RAM, Windows95b [workstation]
Quadra 605, 20 MB of Ram, MacOS7 [workstation]
All of this is connected via TP cables with an 8 port hub.
I'm not currently hooked up to the net, but will probably in a short
little while.
As you can see I'm making the best out of what I've got.
(* - FreeBSD 3.2 has been crashing so many times and acting just
totally weird, that this will be replaced shortly by Slackware. This
is not to start a flame war or anything, just my experience to date)
First of all, DNS. I got my DNS up and running (many thanks to
the ever powerful Olszewski duo), and it's doing a fine job on my
local network. Setting up secondary was a joke, after that (and not
because it runs on a 386 with 8 MB of RAM).
Now I've been teaching myself Sendmail, and after reading the Bat
book 3 times, I've started to understand things (it's a long way to
work, in case you are wondering).
The Bat book mentions MX records for a host. All mail generated
on that host, will be sent to the hub (configuration files are neatly
explained in the Bat book on how to create a client based
Sendmail.cf and how to change Sendmail from daemon to check
just the queue every 30 mins).
Now, from what I understand, the Bat book talks about one host.
That one host has an MX entry which redirects mail to the mail hub
(which is in the process of being configured). If I have multiple
machines, as stated above, and their mail as well goes (will go) to
the hub, do I need to set up MX records for each of the machines
pointing at the hub?
Does the hub need an MX entry to point at itself? From what I
understand from the Bat book, that's what it seems to imply, but I
am not totally sure.
Lastly, Sendmail. Setting up a configuration file for a client based
Sendmail program that only handles the queue locally and forwards
all mail to the hub was relatively easy with the use of the m4
program. However, the actual hub's Sendmail program, does
anyone have any recommendations on settings, or can I leave it as
is? This machine will eventually be hooked to the net probably via
ADSL (and the ever wonderful PPPoe I had the pleasure to learn
and setup for a friend) and albeit I will be setting up a program with
my server to handle my ever changing IP number, no mail (unless I
change idea), will be received from the outside world (just local
messages)-- only outbound messages will be sent.
Thank you again all for reading up to this line.
Regards.
