[Mailman-Users] FW: (fwd) Re: Phantom or unknown address for mailing lists

Hello all:

I am helping Steve work on the mailman and postfix setup on the new server.

Here is what is actually happening:

When I send an email directly to a user that exists in the alias or mailbox
table with username at theglobalvoice.info postfix delivers the email just

Now when I send an email to a mailman list such as
mailman at theglobalvoice.info I get no message back.

When I look in the maillog file I see an error that says user unknown
mailman at theglobalvoice.info.

When I send a message to mailman at mail.theglobalvoice.info mailman picks up
the message and delivers it  just fine.

In mm_cfg.py I added the following lines after mailman was installed:

MTA = 'Postfix'
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['theglobalvoice.info']

I added the references to the aliases and virtual-mailman files in main.cf
for postfix like so:
Alias_maps = hash:/etc/aliases, hash:/usr/local/mailman/data/aliases
Virtual_alias_maps = proxy:mysql:/etc/postfix/mysql_virtual_alias_maps.cf,

I installed mailman by compiling its source code.

I ran configure with the following options:
./configure --with-mailhost=theglobalvoice.info

I did copy the lists over from the old server and ran bin/withlist -r -a -l

That script ran with out any errors.

I ran bin/genaliases and it created the aliases and virtual-mailman files.

Is there anything else I need to look at?

I administer a server for ACB and I have the same setup and it works fine.

The only major difference between the server administer and the one that
Steve administers is I am running Ubuntu 12.04 lts and he is running

I don't think it matters but thought I would share that bit of information
in case there is something with the OS I need to check out.

Where exactly do you see this? Is it in the list's admin General Options
-> host_name and the list posting address on the list's listinfo page?

If so, you can change the host_name and verify things like
DEFAULT_EMAIL_HOST and add_virtualhost email hosts in mm_cfg.py and maybe
run fix_url. See <http://wiki.list.org/x/4030616>.

If headers of email messages are being rewritten, see
