[otrs] Proposal of how to setup OTRS on Ubuntu 7.04 server

[Anders Karlin]

It was piece of cake to setup the LAMP-server and install OTRS with
apt-get but I'am unsure how to setup a secure mailserver. I own a domain
that I want to dedicate for this.

I could use the domain with google apps to setup a mailaccount but google
only let me only connect by POP3+SSL and SMTP+TLS. I found an module for
OTRS to connect to POP3+SSL but I guess it wasn't configed for ubuntu
because I can't get it working.

I installed Postfix after an HOWTO-guide and I think it works but I'am
unsure how secure it is. I don't want do be abused to send SPAM.

So I would like some links or help how I should solve my problem. I'am not
totaly a newbi to linux but I'am unsure when it comes to setup an secure
mailsystem.
