Re: [mlmmj] mlmmj error: "Have to invoke either as root or as the user owning listdir"

For postfix, a small howto:

1) make sure the files/dirs are owned by the user mlmmj, and then in 
/etc/postfix/master.cf, create the transport (here called "mlmmj") to 
run as that specific user mlmmj:

mlmmj   unix  -       n       n       -       -       pipe
   flags=ORhu user=mlmmj argv=/usr/bin/mlmmj-receive -F -L 
/var/spool/mlmmj/${nexthop}

2) After that, in /etc/postfix/virtual, create an alias for your 
mailinglist (here "my.list@mylist-domain") to point to a local delivery:

my.list@mylist-domain [email protected]

3) And then in /etc/postfix/transport, point that alias to use the 
transport ("myreallistname" is the directory under /var/spool/mlmmj for 
your list, it is used as $nexthop in the mlmmj-transport definition above ):

[email protected]   mlmmj:myreallistname

4) Don't forget to run 'postmap' on the files /etc/postfix/virtual and 
/etc/postfix/transport and make sure your postfix uses them in 
/etc/postfix/main.cf, together with your list domain:

virtual_mailbox_domains = mylist-domain
virtual_alias_maps = hash:/etc/postfix/virtual
transport_maps = hash:/etc/postfix/transport

5) postfix reload and off you go :-)

Greetings,

I just installed mlmmj on SuSE Linux Enterprise Server 15 SP4
running a mail server thanks to postfix and dovecot.

I can create a mailing list and subscribe my e-mail with
mlmmj-sub without any problem.

When I get the e-mail from mlmmj, I send the answer accepting
the subscription but get a new e-mail in return from mlmmj
sying:

Subject: Undelivered Mail Returned to Sender

This is the mail system at host <MY_SERVER>.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The mail system

<mlmmj_list_1_dav+confsub-55f8b4567a40e8c8-eric.davanture=orange.fr@MY_DOMAIN.com> :
Command died with status 1: "/usr/bin/mlmmj-receive -L
/var/vmail/mlmmj/mlmmj_list_1_DAV/". Command output: Have to invoke either
as root or as the user owning listdir

I am blocked here and can't reach
finding what the problem could be.

Any help will be greatly appreciated.

Thanks a lot by now.
