* Remove o=mailHosting from the LDAP directory suffix.Guilhem Moulin2015-06-071
| | | | | | So our suffix is now a mere 'dc=fripost,dc=org'. We're also using the default '/var/lib/ldap' as olcDbDirectory (hence we don't clear it before hand).

* Configure SyncRepl (OpenLDAP replication) and related ACLs.Guilhem Moulin2015-06-071
| | | | | | | | | | | | | | | | | | | | | | | The clients are identified using their certificate, and connect securely to the SyncProv. There are a few workarounds (XXX) in the ACLs due to Postfix not supporting SASL binds in Wheezy. Overview: - Authentication (XXX: strong authentication) is required prior to any DIT operation (see 'olcRequires'). - We force a Security Strength Factor of 128 or above for all operations (see 'olcSecurity'), meaning one must use either a local connection (eg, ldapi://, possible since we set the 'olcLocalSSF' to 128), or TLS with at least 128 bits of security. - XXX: Services may not simple bind other than locally on a ldapi:// socket. If no remote access is needed, they should use SASL/EXTERNAL on a ldapi:// socket whenever possible (if the service itself supports SASL binds). If remote access is needed, they should use SASL/EXTERNAL on a ldaps:// socket, and their identity should be derived from the CN of the client certificate only (hence services may not simple bind). - Admins have restrictions similar to that of the services. - User access is only restricted by our global 'olcSecurity' attribute.
* Enable zero-copy updates to the LDAP directory.Guilhem Moulin2015-06-071

* Assume a DNS entry for each role.Guilhem Moulin2015-06-071
| | | | | | E.g., ldap.fripost.org, ntp.fripost.org, etc. (Ideally the DNS zone would be provisioned by ansible, too.) It's a bit unclear how to index the subdomains (mx{1,2,3}, etc), though.
* Fix the catch-all resolution again.Guilhem Moulin2015-06-071
| | | | | | | | | | | | | | | | | | | | We introduce a limitation on the domain-aliases: they can't have children (e.g., lists or users) any longer. The whole alias resolution, including catch-alls and domain aliases, is now done in 'virtual_alias_maps'. We stop the resolution by returning a dummy alias A -> A for mailboxes, before trying the catch-all maps. We're still using transport_maps for lists. If it turns out to be a bottleneck due to the high-latency coming from LDAP maps, (and the fact that there is a single qmgr(8) daemon), we could rewrite lists to a dummy subdomain and use a static transport_maps instead: virtual_alias_maps: mylist@example.org -> mylist#example.org@mlmmj.localhost.localdomain transport_maps: mlmmj.localhost.localdomain mlmmj:
* Mailing lists (using mlmmj).Guilhem Moulin2015-06-071
| | | | | | | | | Right now the list server cannot be hosted with a MX, due to bug 51: http://mlmmj.org/bugs/bug.php?id=51 Web archive can be compiled with MHonArc, but the web server configuration is not there yet.
* Remove list commands.Guilhem Moulin2015-06-071
| | | | | | They were only a dirty hack for list commands à la Mailman such as mylist-request. If we are to use another list manager such as mlmmj, which uses a VERP delimiter instead, the problem disappears.
* Remove the 'fripostLocalAlias' attribute.Guilhem Moulin2015-06-071
| | | | | | | | | | | | | Instead, we pretend that lists are valid users (via a match in the mailbox_transport_maps) but choose a different transport (with the same request in transport_maps). The advantage is that we get rid of the ugly hack for list transport… A minor drawback is that we now have two LDAP lookups instead of one for non local addresses (ie, everything but reserved addresses). Hopefully the requests are cached; but even if they aren't, querying a local LDAP server is supposed to be cheap.
* Configure dovecot's antispam filter.Guilhem Moulin2015-06-071
| | | | | | | | | | | | | Mails to be retrained are stored in the spooldir /home/mail/spamspool; later a daemon catches them up and feed them to sa-learn(1p). (On busy systems batch-process the learning should be much more efficient.) The folder transisition matrix along with the corresponding actions can be found there: http://hg.dovecot.org/dovecot-antispam-plugin/raw-file/5ebc6aae4d7c/doc/dovecot-antispam.7.txt See also dovecot-antispam(7).

* Configure the content filter.Guilhem Moulin2015-06-071
| | | | | | | | | | | Antispam & antivirus, using ClamAV and SpamAssassin through Amavisd-new. Each user has his/her amavis preferences, and own Bayes filter (to maximize privacy). One question remains, though: how to set spamassassin's trusted_networks / internal_networks / msa_networks? It seems not obivious to get it write with IPSec and dynamic IPs. (Cf. https://wiki.apache.org/spamassassin/AwlWrongWay)
