mail server setup? using free DNS services. ultimate setup needed

[mnewbegin]

I have setup my server at work; it is going to be for mail/web server functions.

I followed the link here

http://www.howtoforge.com/perfect_setup_ubuntu704

Setup guide

But when I try to send mail out it comes as


name@servername.domain.com
instead of
name@domain.com

I know I can change this but during the install it said to use localhost, localhost.domain.com and a few others for the name, to make sure mail sends correctly.

My other problem is I am using webmin, I love it but everyone says it’s harder to configure than ispconfig, it looks so nice though and seems to do the trick.


My 2 main concerns are getting the domain name settled and getting incoming mail working. I am not using bind, I am using free dns servers, and they provide me with 4 name servers. I am using “everydns” service, but I don’t know how to add a MX record for that service, do I just make one that’s called mail.domain.com or mx.domain.com
And point it to my IP address and my server will do the rest?

I cannot receive mail to this box now because I have no incoming mail server configured.


I have a static IP address, and can buy another if I need a second IP address.

Please help,

Ultimately I want to end with I will be shooting for hosting, my mailserver that will provide services for 60 email clients,


PLEASE HELP. I WILL TRY ANYTHING THAT WILL WORK.

also what program should i use for a gui interface?

squirrelmail ? and do you recommend postfix or other for this number of clients.


a step by step guide start to finish just configuring mailserver part would be excellent.

You must set the correct sender address in your email client (e.g. Thunderbird, Outlook, Evolution,...).

You must create an A record for mail.domain.com or mx.domain.com (doesn't matter) which points to your server's public IP address, and then you must create an MX record like this:

domain.com. MX 10 mail.domain.com.

or

domain.com. MX 10 mx.domain.com.

Of course, Postfix must be configured to accept emails for domain.com. You can either do this with webmin or on the command line: http://www.howtoforge.com/forums/showthread.php?t=2

You don't need a second IP address.

Squirrelmail is fine.

You can't go wrong with Postfix.

Ive caught on to most of what I had to do for this stuff but im still lost, I started over with a fresh install.


When I was using the perfect setup ubuntu 7.04 tutorial,

What do i type here

The directions say

echo server1.example.com > /etc/hostname

my hostname right now is ubuntu

but for my mail to resolve correctly, do I change this to

mx.example.com or just plain example.com


and then further down in the instructions I what do I use for.

Mailname?

and other destinations to accept mail for?


on the ubuntu page https://help.ubuntu.com/7.04/server/C/postfix.html


they show an example of mail.example.com

I have configured mx.domain.com to goto my ip address all ready.


sorry some of the generic directions mess with my head during the setup, if someone posts an example just make a fake company name please.

First you must make up your mind which hostname you want to use (e.g. ubuntu.yourdomain.com). Then you simply replace server1.example.com with ubuntu.yourdomain.com.
ubuntu.yourdomain.com should have an A record pointing to your server. If you want to receive emails for yourdomain.com, you create an MX record like this:

yourdomain.com MX 0 ubuntu.yourdomain.com

hopefully this will help me and others,

here are screenshots of what I have.

how do i fix this.

I will post any file needed here so i can get this working.

I thought, a picture speaks a thousand words, so where could i go wrong.

there has to be something wrong with my setup.

mail goes out, but doesnt come in.

I am running postfix, dovecot, im installing squirrelmail soon, and hopefully I will have this working today.

I hope I have all the available ports and things open.


I can do a clean install if i need to.

The DNS records look ok (if 216.220.234.160 is your server's IP address).

What's the output of

postconf -n

and

netstat -tap

? Any errors in your mail log?

ls -la /etc/postfix
