Did you already run the geniuses command so that Mailman can recognize your
new list?
The documentation says:
```
6.1.1 Integrating Postfix and Mailman
You can integrate Postfix and Mailman such that when new lists are
created, or lists are removed, Postfix's alias database will be
automatically updated. The following are the steps you need to take to
make this work.
In the description below, we assume that you've installed Mailman in
the default location, i.e. /usr/local/mailman. If that's not the case,
adjust the instructions according to your use of configure's --prefix
and --with-var-prefix options.
Note: If you are using virtual domains and you want Mailman to honor
your virtual domains, read the 6.1 section below first! Then come back
here and do these steps.
* Add this to the bottom of the $prefix/Mailman/mm_cfg.py file:
MTA = 'Postfix'
The MTA variable names a module in the Mailman/MTA directory which
contains the mail server-specific functions to be executed when a
list is created or removed.
* Look at the Defaults.py file for the variables POSTFIX_ALIAS_CMD
and POSTFIX_MAP_CMD command. Make sure these point to your
postalias and postmap programs respectively. Remember that if you
need to make changes, do it in mm_cfg.py.
* Run the bin/genaliases script to initialize your aliases file.
% cd /usr/local/mailman
% bin/genaliases
Make sure that the owner of the data/aliases and data/aliases.db
file is mailman, that the group owner for those files is mailman,
or whatever user and group you used in the configure command, and
that both files are group writable:
% su
% chown mailman:mailman data/aliases*
% chmod g+w data/aliases*
* Hack your Postfix's main.cf file to include the following path in
your alias_maps variable:
/usr/local/mailman/data/aliases
Note that there should be no trailing .db. Do not include this in
your alias_database variable. This is because you do not want
Postfix's newaliases command to modify Mailman's aliases.db file,
but you do want Postfix to consult aliases.db when looking for
local addresses.
You probably want to use a hash: style database for this entry.
Here's an example:
alias_maps = hash:/etc/postfix/aliases,
hash:/usr/local/mailman/data/aliases
* When you configure Mailman, use the --with-mail-gid=mailman switch;
this will be the default if you configured Mailman after adding the
mailman owner. Because the owner of the aliases.db file is mailman,
Postfix will execute Mailman's wrapper program as uid and gid
mailman.
That's it! One caveat: when you add or remove a list, the aliases.db
file will updated, but it will not automatically run postfix reload.
This is because you need to be root to run this and suid-root scripts
are not secure. The only effect of this is that it will take about a
minute for Postfix to notice the change to the aliases.db file and
update its tables.
