I want to install and run it and play with it like a user. I'm not a python
developer (at least not yet, and not sure if I'll ever get that far).

OK. Thanks for the advice.

I'll detail my steps in case it helps someone else. (I also have a few
questions mixed in below.) Here's what I did:

install Ubuntu 12.04
create DNS records
ssh into Ubuntu server
sudo apt-get install build-essential python-dev python-virtualenv
cd /opt/
wget
https://launchpad.net/mailman/3.0/3.0.0b1/+download/mailman-3.0.0b1.tar.gz
tar -xf mailman-3.0.0b1.tar.gz
mkdir mailman3 (for virtualenv - see note below about correcting my
directory names; this should have been named mailman3_venv)
# virtualenv /opt/mailman3/
(New python executable in /opt/mailman3/bin/python)

I do recommend creating an etc/mailman.cfg to customize various aspects of

# nano /etc/mailman.cfg
done

sudo apt-get install postfix openssl-blacklist ssl-cert

# nano /etc/postfix/main.cf

***************** QUESTION *********************
Are the following paths correct???
transport_maps =
    hash:/opt/mailman3/var/data/postfix_lmtp
local_recipient_maps =
    hash:/opt/mailman3/var/data/postfix_lmtp

*******************************************************

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.
root at li437-28:/etc/postfix# /etc/init.d/postfix reload
 * Reloading Postfix
configuration...                                                       [ OK
]

# source /opt/mailman3/bin/activate
python setup.py install
    Finished processing dependencies for mailman==3.0.0b1

NOTE: After doing all this, I see that I named my directories wrong. I
think I'll repeat it and name the extracted tarball directory mailman3/ and
the virtualenv directory mailman3_venv/ next time.


 Now you can run `mailman info` to get some basic information about how your
> system is configured,


(mailman3)root at localhost:/opt/mailman-3.0.0b1# mailman info
GNU Mailman 3.0.0b1 (The Twilight Zone)
Python 2.7.3 (default, Apr 20 2012, 22:39:59)
[GCC 4.6.3]
config file: /etc/mailman.cfg
db url: sqlite:////opt/mailman-3.0.0b1/var/data/mailman.db
REST root url: http://mailman3.example.com:80/3.0/
REST credentials: yyyyyyyyyyyy:xxxxxxxxxxxxx

Thank you! That's a great help.

I also came across this useful tutorial:
Python Ecosystem - An Introduction
http://mirnazim.org/writings/python-ecosystem-introduction/

Next Questions:
1. what are the first tests I should perform after starting mailman?
2. a tutorial for setting up Posterious?

Thanks again.
