* 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.
* Don't use generic maps.Guilhem Moulin2015-06-071
| | | | | | | | | | | | | | | | | In fact we want to only rewrite the envelope sender: :/etc/postfix/main.cf # Overwrite local FQDN envelope sender addresses sender_canonical_classes = envelope_sender propagate_unmatched_extensions = sender_canonical_maps = cdb:$config_directory/sender_canonical :/etc/postfix/sender_canonical @elefant.fripost.org admin@fripost.org However, when canonical(5) processes a mail sent vias sendmail(1), it rewrites the envelope sender which seems to *later* be use as From: header.

* Share master.cf accross all Postfix instances.Guilhem Moulin2015-06-071
| | | | | | And use main.cf's 'master_service_disable' setting to deactivate each service that's useless for a given instance. (Hence solve conflict when trying to listen twice on the same port, for instance.)

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