Re: Postfix Configuration



You may get a lot of questions answered by experimenting with the the following script and looking at how they set it up the system.

I can't comment on the manual setup of a LAMP mail server setup as my expertise is not there however I am very familiar with the GPL version of the Virtualmin script to setup either a Centos5 or Debian server.

I setup a vpslink-5 / Centos4 server using the Virtualmin Pro install script (the pay version of the script) which is so magical to me that it is seemingly sent to us by the Ancients if you're familiar with SG1 :-)

A lot of the pro version has trickled down into the GPL version now. Most notably the install script.

They now offer a GPL version of the script for Centos5 and Debian
http://www.webmin.com/virtualmin.html

The links on the left under Virtualmin Links are the ones you may want to read about and try.
http://www.webmin.com/vinstall.html

You will have to rent a temporary secondary vpslink server to experiment so you don't mess up your manual install but it may be worth every penny to try it.

You can setup virtualmin manually under webmin but it really is a complex setup so the setup script is the way to go.

Also I had to manually install yum and the other program that Centos requires for installing programs because the initial vpslink server is very minimal.

This may not be the case anymore since it has been a long time since I set this up but I had to modify the path to these programs in the install script. Once that is done you run the script and just set back and watch the magic.
That was back in the early adopter days so maybe the script has evolved a bit since then.

I am going to experiment with the
Virtualmin on EC2 setup in the near future. It's a bit pricey if you run it 24-7 but for experimentation it is reasonable.

Hope this helps,

I hope you are all doing well!  Happy Thanksgiving.  It's been a while
since I've been to the luci site.  I thought I would run something by you.

I bought one of the virtual servers at vpslink.com.  I'm very happy with
it, and right now am running Link (package) 2 with 5 Gigs hdd space, and
128 Megs of RAM.  Accessing the server through Secure shell.  The server
is an a LAMP configuration.

I'm really trying to stay completely non-proprietary with this server, so
am setting up everything manually without licensed software such as
cpanel.  It's mostly a learning experience for me.

Apache is up and running perfectly, and so are the virtual hosts.  I'm
going to host several websites on this machine.

The problem I'm running into is in the postfix configuration for the
virtual hosts.

I know I can get postfix to run with squirrelmail because it's on the
local machine, and I'm only using squirrelmail for the local host account.

I'm trying to take this issue one step at a time, so the first thing I
would like to do is to get postfix to receive mail from
ricky@ethernetgateway.com, and map the mail to the rbryce account on the
virtual machine.  I'm wanting to use separate mailboxes with system
accounts, so I think Aliasing is the way to do this.

Consider a default LAMP configuration with sendmail erased and postfix and
dovecot installed.  Also, please consider, this is the first time I've
tried to configure postfix.  I do have Webmin installed also, and SSL
enabled.

If I go to main.cf in /etc/postfix/,

alias_maps = hash:/etc/aliases is uncommented

rbryce is an existing UNIX system user (created by adduser)

In /etc/aliases (at the very bottom of the file rbryce:
ricky@ethernetgateway.com exists

I've used the command postconf -e "virtual_alias_domains =
ethernetgateway.com

and

postconf -e "virtual_alias_maps = hash:/etc/postfix/virtual"

To create a map database, I've typed

postfix /etc/postfix/virtual

(restarted postfix)

When I go to yahoo, and send a message to my ricky@ethernetgateway.com
address, I am not getting a bounce.

When I su to rbryce on the server, and type "mail" I get "no mail for
rbryce" when I would have expected to receive a message.

If anyone could point me in the right direction I would appreciate it... 
Or even recommend a good web document, it would be appreciated.  Maybe I
have some conceptual errors as to how to configure the mail.  Once I get
postfix running right, I'll be happy with this server.  (I'm happy
already!)

Take care!

Ricky Bryce
