In trying to follow the Ubuntu guide for postfix and mailman, I do not understand these directions:

This build of mailman runs as list. It must have permission to read /etc/aliases and read and write /var/lib/mailman/data/aliases. Do this with these commands:

sudo chown root:list /var/lib/mailman/data/aliases
sudo chown root:list /etc/aliases

Save and run:

sudo newaliases

I'm getting this kind of error:

And am wondering what connection might be. I do see that I don't have the requisite files:

root@dur:~# 
root@dur:~# ll /var/lib/mailman/data/aliases
ls: cannot access /var/lib/mailman/data/aliases: No such file or directory
root@dur:~# 

At what stage were those aliases created? How can I create them? Is that what's causing the error error: open database /var/lib/mailman/data/aliases.db: No such file or directory Aug 28 01:17:22 dur postfix/smtpd[19709]: connect from localhost[127.0.0.1]?

At what stage were those aliases created?

Installing mailman only copies the installation files in /var/lib/mailman:

# ls -l /var/lib/mailman/data/
total 16
-rw-rw-r-- 1 root list    10 Aug 28 16:08 last_mailman_version
-rw-r--r-- 1 root list 14100 Jul 18 00:45 sitelist.cfg

How can I create them?

$ sudo /usr/lib/mailman/bin/genaliases

$ ls -l /var/lib/mailman/data/
total 20
-rw-rw---- 1 root list   355 Aug 28 16:46 aliases
-rw-r----- 1 root list  3072 Aug 28 16:46 aliases.db
-rw-rw-r-- 1 root list    10 Aug 28 16:08 last_mailman_version
-rw-r--r-- 1 root list 14100 Jul 18 00:45 sitelist.cfg

Is that what's causing the error error: open database /var/lib/mailman/data/aliases.db: No such file or directory Aug 28 01:17:22 dur postfix/smtpd[19709]: connect from localhost[127.0.0.1]?

Yes.

but what is in /var/lib/mailman/data/aliases? help.ubuntu.com/community/Mailman#Postfix_Configuration doesn't specify. –  Thufir Aug 28 '12 at 9:22
