* Replace IPSec tunnels by app-level ephemeral TLS sessions.Guilhem Moulin2015-06-071
| | | | | For some reason giraff doesn't like IPSec. App-level TLS sessions are less efficient, but thanks to ansible it still scales well.

* 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.

* Fix catchall resolution.Guilhem Moulin2015-06-071
| | | | | | | | It has to be performed last, to give a chance to be accepted as a regular mailbox. We introduce a new, dedicated, smtpd daemon whose only purpose is to resolve catch-alls.

* Use a dedicated SMTP port for samhain.Guilhem Moulin2015-06-071
| | | | | | | It's unfortunate that samhain cannot use the sendmail binary, and wants to use a inet socket instead. We use a custom port to avoid conflicts with the usual SMTP port the MX:es need to listen on. See also: /usr/share/doc/samhain/TODO.Debian

We use a dedicated instance for each role: MDA, MTA out, MX, etc.
