dovecot - Nov 2003 - deliver mail with postfix to dovecot for mailinglists

This is a bit off topic on that list. But the question is
required because of a limitation of dovecot. It cannot
have shared mailboxes into which one would collect mailing list
mails. I assume one has already solved that problem and
therefore ask this question on that list.

I try to do the following:
   I would like to setup an alias dovecot at kzone.ch
   and subscribe this alias to the dovecot mailing list. Then
   I would like to create an alias to run maildrop with the
   correct parameter to put it into the directory
   ~ski/Maildir/.dovecot/. Of course, there is no user dovecot
   on my system and if there would be one she couldn't
   write to a directory owned by me.

Is there a trick to do the following:

ski	->	~ski/Maildir
dovecot	->	~ski/Maildir/.dovecot
postfix	->	~ski/Maildir/.postfix

Any other idea?

Any good documentation on that?

You might be able to achieve this with the virtual(8) delivery
agent, since it can target arbitrary directories and UIDs.

Also consider the "+" separator, as in user+foo at domain, which is
integrated with the virtual(5) lookup in a reasonably intelligent way
and may suit you.

Of course, what we could really do is implement SIEVE (RFC3028)
in a LMTP delivery agent for Dovecot.  It'd attract a lot of the
people currently depending on Cyrus.

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...
