The nicest way to run a lists.example.com with EoC and Postfix
==============================================================

This is the nicest way I have seen so far.

Development versions of eoc are able to take SENDER and RECIPIENT and
command line args, and have sane behaviour with --incoming without the
need for --is-list. When they are available for production use, the
extra shell script can be removed.


Add a user and group "eoc" with home directory /var/lib/eoc. Create lists as that user.

$ sudo adduser --system --home /var/lib/eoc --gecos 'Mailing Lists' --group --disabled-password --disabled-login eoc


/etc/postfix/master.conf:

--8<--
eoc     unix    -       n       n       -       2       pipe
  flags=R user=eoc
  argv=/usr/bin/eocmanage-deliver ${sender} ${recipient}
--8<--

/etc/postfix/main.conf:

--8<--
eoc_destination_recipient_limit = 1
transport_maps = hash:/var/lib/eocmanage/postfix/transport,
		 pcre:/var/lib/eocmanage/postfix/transport.pcre
--8<--

/var/lib/eocmanage/postfix/transport:

--8<--
lists.example.com       eoc:@lists.example.com
--8<--

/var/lib/eocmanage/postfix/transport.pcre:

--8<--
/^someprefix(-(foo|bar)?)@example\.com$/       eoc:someprefix@lists.example.com
--8<--

sudo postmap /var/lib/eocmanage/postfix/transport
sudo /etc/init.d/postfix reload
