* Don't merge amavis' logs into /var/log/syslog.Guilhem Moulin2015-06-071
| | | | | As they contain user information, we keep it in /var/log/mail.log only. These logs are kept for 3 days "only", as per our policy.

* Replace Postgrey with postscreen.Guilhem Moulin2015-06-072
| | | | | | | | | | | See http://www.postfix.org/POSTSCREEN_README.html and http://rob0.nodns4.us/postscreen.html It's infortunate that smtpd(8) cannot be chrooted any longer, which means that we have to un-chroot cleanup(8) as well. Indeed, currently smtpd(8) uses $virtual_alias_maps for recipient validation; later cleanup(8) uses it again for rewriting. So these processes need to be both chrooted, or both not.

* Perform the alias resolution and address validation solely on the MX:es.Guilhem Moulin2015-06-071
| | | | | We can therefore spare some lookups on the MDA, and use static:all instead.
* Fix Amavis' Policy Banks.Guilhem Moulin2015-06-071
| | | | | | | | | | | It turns out that in a policy bank, a *_by_ccat doesn't replace the default but is merely merged into the default (if the keys overlap, those in the bank take precedence of course). Hence it's pointless to use CC_CATCHALL in a bank unless all the other keys have been overridden, for instance. Also, treat unchecked (eg, encrypted) mails as clean in the OUTGOING Policy Bank.
* Add a logcheck rule to ignore cyrus' annoying log messages.Guilhem Moulin2015-06-071
| | | | Namely, "DIGEST-MD5 common mech free". See also bug #631932.
* Postfix needs to be restarted after rekeying.Guilhem Moulin2015-06-071
| | | | (It opens the key as root, but then drops the permissions.)
* Add a tag 'tls_policy' to facilitate rekeying.Guilhem Moulin2015-06-071
| | | | | First generate all certs (-t genkey), then build the TLS policy maps ( -t tls_policy).
* 'default_days' in openssl.cnf doesn't work, use -days instead.Guilhem Moulin2015-06-071

* 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.
* Add ability to add custom OrganizationalUnits in genkeypair.Guilhem Moulin2015-06-072
| | | | Also, it's now possible to reuse an existing private key (with -f).

* Increase the timeout in the smtpd waiting for the reinjection from amavis.Guilhem Moulin2015-06-071
| | | | | | | | SMTP client connection caching was introduced in 2.6.0: the SMTP session is held for the next task (in adaptative mode, only when there was a delay of only 5s between the two previous mails), but Postfix will terminate it if the next mail doesn't come soon enough, or if amavis does't terminate it itself (usually after 15s).

* Reload Postfix upon configuration change, but don't restart it.Guilhem Moulin2015-06-072
| | | | | | (Unless a new instance is created, or the master.cf change is modified.) Changing some variables, such as inet_protocols, require a full restart, but most of the time it's overkill.
* Don't restart/reload Postifx upon change of a file based database.Guilhem Moulin2015-06-071
| | | | | | And don't restart or reload either upon change of pcre: files that are used by smtpd(8), cleanup(8) or local(8), following the suggestion from http://www.postfix.org/DATABASE_README.html#detect .

* Whitelist our IPs against fail2ban.Guilhem Moulin2015-06-071
| | | | | | | This is important as we don't want the IMAP server baning the webmail, for instance. (The fail2ban instance running next to the webmail should ban the attacker, but that running next to the IMAP server shouldn't ban legit users.)

* Replace IPSec tunnels by app-level ephemeral TLS sessions.Guilhem Moulin2015-06-077
| | | | | 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 Moulin2015-06-073
| | | | | | | | | | | | | | | | | 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.

* Don't require a PKI for IPSec.Guilhem Moulin2015-06-075
| | | | | | | | | | | Instead, generate a server certificate for each host (on the machine itself). Then fetch all these certs locally, and copy them over to each IPSec peer. That requires more certs to be stored on each machines (n vs 2), but it can be done automatically, and is easier to deploy. Note: When adding a new machine to the inventory, one needs to run the playbook on that machine (to generate the cert and fetch it locally) first, then on all other machines.
