[Dovecot] deliver mail with postfix to dovecot for mailinglists

[Sven Kirmess]

I found an interesting document, describing how to use
majordomo with postfix which I used to do what I want.
(Actually, I didn't find anything to my problem. So I tried
to set up majordomo... ;-)

http://www.csh.rit.edu/~jon/projects/majordomo/#postfix

That's what I did (ski is my login):

1) Create the mailbox where you would like to receive the
    mailing list into. I used my IMAP client and create a
    group called ml.test1

2) # mkdir /etc/postfix/mailing_list
    # mkdir /etc/postfix/mailing_list/ski
    # chown ski:ski /etc/postfix/mailing_list/ski

3) su - ski
    > cd /etc/postfix/mailing_list/ski
    > vi aliases
    test1:          /var/spool/imap/ski/.ml.test1/

    > /opt/postfix/sbin/postalias /etc/postfix/mailing_list/ski/aliases
    > ^D

4) # vi /etc/postfix/main.cf
    alias_maps = dbm:/etc/aliases, dbm:/etc/postfix/mailing_list/ski/aliases

    # /opt/postfix/sbin/postfix reload



Now, whenever a mail to user test1 arrives, the alias is read
from the file /etc/postfix/mailing_list/ski/aliases. Because
there is no user test1 the delivery is done as the owner of the
alias file, ski in this case. ski can write to ski's Maildir,
of course...
