It is only DNS and the mail server daemons that must know about each other as mail coming in will be kept or discarded based on the destination username and domain name it is sent to.

First, Steve it's great of you to go to all this effort. Thanks in advance.
Now I wonder if you'll be surprised at how early in the procedure things
fell apart for me. :)

My lan is set up as follows. My workstation 192.168.0.1 runs windows xp and
shares its dialup connection through ics. In its host file it maps my fbsd
box 192.168.0.7 to the server name swamisalami. This allows me to ftp, ssh,
and also browse to http://swamisalami from my workstation and afaik any
other box on the lan.
I use eudora as my email client on the workstation and set up a personality
for [EMAIL PROTECTED] I was able to successfully send the following

[EMAIL PROTECTED]
From: Marty Landman [EMAIL PROTECTED]
Subject: testing
Mime-Version: 1.0
Content-Type: text/plain; charset=us-ascii; format=flowed
This is a test. If this were an actual email...
Oh.
However, I don't know how to receive email from outside my lan on the fbsd
box, nor how to send mail from the fbsd box to other locations.
Besides that I just managed to delete a user's mailbox and don't know how
to recreate it. But that just seems to be an omen of how much trouble this
is going to take overall. Just part of the learning hyperbola, uh curve --
yeah.
*update* - I received one of the test email msgs; apparently mail (or
sendmail) created the /var/mail/marty file on the fly, then removed it
again once I deleted the msg. btw, what is the cockamamie mbox thingie
about and how do I manage it? uh, sorry about the value judgement implied
in that stmt.
You can try this with the #dig command:
Thx, this seems a bit more informative in a way than #whois.
- the IP of your mail server is 192.168.0.10
How do I find out what sendmail's ip adr is? What about the mail server
that Eudora uses on the winxp box, does that enter into this if I want to
be able to send/receive email on the internet from the fbsd box?
- your default gateway for your network is 192.168.0.1
AFAIK that's right since this is the winxp/dialup shared box's ip.
- your mail server name is mail.example.com
Now I'm lost. Do you mean the name of my ISP's email server?
1 Set up DNS on the server
# cd /etc/namedb
# chmod 744 make-localhost
# ./make-localhost
Question here since I'm so new. Looks like make-localhost's an exec that
I've just executed. But when I created /tmp/scratch
FreeB ./tmp/scratch
./tmp/scratch: Command not found.
FreeB more /tmp/scratch
#!/bin/sh
echo Hello World
# ee named.conf
Add the following to the bottom of the file:
zone example.com {
type master;
file example.com.zone;
allow-update { none; };
};
Stopped here since I'm unclear about how to sub for example.com but am
leaving the rest of your instructions intact for followup.
Marty
Then, up near the top of the file, make the following changes to this
section:
# Remove the // from this line:
// forward only;
# and remove the /* and the */ from this section, and change the
127.0.0.1 to the IP address of your ISP DNS server:
/*
forwarders {
127.0.0.1;
};
*/
Now create a zone file for this zone:
# ee /etc/namedb/example.com.zone
Add the following information to this empty file:
--- start clip here ---
$TTL 360 ; Default cached time to live for all records
example.com.IN SOA ns.example.com. [EMAIL PROTECTED]
(
2003120401; Serial

mailIN A192.168.0.10
client IN A192.168.0.25
router IN A192.168.0.1
--- end clip ---
Now, tell your name server to look to itself for resolution of names:
# echo search example.com /etc/resolv.conf
# echo nameserver 127.0.0.1 /etc/resolv.conf
Now go configure your windows or whatever client computers to use
192.168.0.10 as it's DNS server.
2 Start the nameserver and load it at startup:
# /usr/sbin/named
Now, add the following 2 lines to your /etc/rc.conf file:
named_enable=YES
named_program=/usr/sbin/named
3 Configure sendmail
# cd /etc/mail
# echo example.com relay-domains
# echo example.com local-host-names

Like me. So there's at least two of us on the list who need this info. Speaking personally with some prior help I can now email within the box, i.e. id1 can email id2 who can then reply back to id1. However going the next step, receiving email from a remote server and sending email out to the internet is something I have no clue how to do. Don't even know how to start, and the stab I made at following tutorials found by googling got me nowhere at breakneck speed. Not that I'm complaining but you did ask. :) Marty Landman Face 2 Interface Inc 845-679-9387 Sign On Required: Web membership software for your site Make a Website: http://face2interface.com/Home/Demo.shtml ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

First off, email relies very heavily on the DNS infrastructure of the
Internet. DNS or Domain Name Service is what resolves a name, such as
www.freebsd.org to it's IP address. Although it is technically possible
to bypass the name for a mail server to get your messages to their
destination, it is not proper, and many mail systems will not allow it
(especially ones that use virtual domains).
ie. In some cases, you could send a mail message to [EMAIL PROTECTED],
and if the server is listening for incoming mail (sendmail) then it may
pick it up and deliver it to a local user.
Now, further into DNS, a computer must know how to find a mail server
within a domain. When I send a message to [EMAIL PROTECTED],
this is what happens:
- I send a message to [EMAIL PROTECTED] from my laptop to my smtp
server (most would use one their ISP supplied, such as mail.isp.com)
- the smtp server does a reverse name lookup in DNS to find out if the
IP that sent the mail is allowed to relay mail to the remote destination
through it. Reverse lookup is the opposite of resolving names, it is the
process of resolving an IP to a name. You can try this with the #dig
command:
# dig -x your.ip.here
Likewise, you can use dig to resolve a name as well:
# dig www.freebsd.org
- next after the server verifies that you are allowed to relay, it looks
in DNS for a Mail Exchange record (MX) of the domain you are trying to
send the message to:
# dig mx freebsd.org
- once your smtp server finds the IP for the mail exchanger for the
domain, it sends the message to it
- the remote server acknowledges the incoming message, says thanks to
the sending server and shuts down the connection
- the recipient mail server looks in certain tables and/or files to
locate which user the mail actually goes to and delivers it.
For a quick and dirty setup on a FreeBSD box, here are the steps: (I
hope I don't miss any). They assume the following:
- your domain name is example.com, and will only be used for
sending/receiving mail on an internal network
- your mail server is somehow connected to the Internet, and will be
used as an smtp server for the client computers on your network (as you
probably use your ISP s servers now
- your internal network IP scheme is 192.168.0.0/24 (or 255.255.255.0)
- the IP of your mail server is 192.168.0.10
- your default gateway for your network is 192.168.0.1
- your ip of your client computer is 192.168.0.25
- your mail server name is mail.example.com
- your client computer name is client.example.com
- your mail server will back as a qpopper and DNS server for the network
- you are not overly concerned about high security, as this is just an
example to get you up and going
- you are running as the superuser
1 Set up DNS on the server
# cd /etc/namedb
# chmod 744 make-localhost
# ./make-localhost
# ee named.conf
Add the following to the bottom of the file:
zone example.com {
type master;
file example.com.zone;
allow-update { none; };
};
Then, up near the top of the file, make the following changes to this
section:
# Remove the // from this line:
// forward only;
# and remove the /* and the */ from this section, and change the
127.0.0.1 to the IP address of your ISP DNS server:
/*
forwarders {
127.0.0.1;
};
*/
Now create a zone file for this zone:
# ee /etc/namedb/example.com.zone
Add the following information to this empty file:
--- start clip here ---
$TTL 360 ; Default cached time to live for all records
example.com.IN SOA ns.example.com. [EMAIL PROTECTED]
(
2003120401; Serial
172800 ; Refresh every 2 days
3600; Retry every hour
1728000 ; Expire every 20 days
172800 ); Minimum 2 days
@ IN NS ns.example.com.
; Set the Mail Exchange record
@ IN MX 10 mail.example.com.
ns IN A192.168.0.10
mailIN A192.168.0.10
client IN A192.168.0.25
router IN A192.168.0.1
--- end clip ---
Now, tell your name server to look to itself for resolution of names:
# echo search example.com /etc/resolv.conf
# echo nameserver 127.0.0.1 /etc/resolv.conf
Now go configure your windows or whatever client computers to use
192.168.0.10 as it's DNS server.
