[Mailman-Users] Unknown error when creating a new list

[Monica Messa]

I use Postfix as my MTA and get an error like this when creating a new list:

Bug in Mailman version 2.1.5

Configuring Mailman, I execute:

./configure --prefix=/var/virtual/mailman --with-groupname=apache --with-mai
lhost=ct.rupar.puglia.it --with-urlhost=mailman.rupar.puglia.it --with-cgi-g
id=apache --with-mail-gid=apache --with-python=/usr/bin/python2.2

I am able, as mailman user, to run postalias on the aliases file, just fine.

-rw-rw-r--    1 mailman  apache       2766  7 dic 18:48 data/aliases
-rw-rw-r--    1 mailman  apache      12288  7 dic 18:09 data/aliases.db

Can someone help me, so that I can successfullt create lists via the web?
Do you need other information?

Thank you,

Monica M.
