* Don't auto-create home directories when adding system users.Guilhem Moulin2015-06-073
| | | | | Unlike adduser(8), ansible's 'user' module copies skeletal configuration files even for system users (unless called with createhome=no).
* 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.)
* Use stunnel to secure the connection from the IMAP proxy to the IMAP server.Guilhem Moulin2015-06-076
| | | | | | | The reason is that we don't want to rely on CAs to verify the certificate of our server. Dovecot currently doesn't offer a way to match said cert against a local copy or known fingerprint. stunnel does.
* Tel logcheck which logs to monitor.Guilhem Moulin2015-06-071

* Replace IPSec tunnels by app-level ephemeral TLS sessions.Guilhem Moulin2015-06-0723
| | | | | For some reason giraff doesn't like IPSec. App-level TLS sessions are less efficient, but thanks to ansible it still scales well.
* Outgoing SMTP proxy.Guilhem Moulin2015-06-0711
|
* Don't use mailbox list indexes.Guilhem Moulin2015-06-072
| | | | | | | In 2.1.7 they are buggy, and make Dovecot crash (when connected through Evolution for instance). They have improved a lot since, though: http://hg.dovecot.org/dovecot-2.2/file/c55c660d6e9d/NEWS
* Expose the real user ID when using the webmail.Guilhem Moulin2015-06-071
| | | | | | Sadly not doing so and keeping a table message ID -> username, like we do for SASL authenticated users, doesn't seem trivial here. We could encrypt the header, though.

* Don't install 'unhide.rb'.Guilhem Moulin2015-06-072
|
* 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.

* Revert dovecot (imapc) to stable (2.1.7-7+deb7u1).Guilhem Moulin2015-06-072
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There seem to be multiple bugs with the version from wheezy-backports (2.2.9-1~bpo70+1), and the client is killed on THREAD commands: guilhem@elefant:~$ telnet localhost 143 Trying ::1...

However, the bugs (at least the segfault) seems to be fixed as of 2.2.13-1, the version which can currently be found in testing. Hopefully it'll be backported soon :-)

* Install dovecot from backports (for imapc).Guilhem Moulin2015-06-075
| | | | | Interesting features include caching of mail headers (v2.2.8+) as well as new IMAP capabilities.
* Install Rouncube from backports.Guilhem Moulin2015-06-072
| | | | | | Recent versions have a whole bunch of bugfixes and nice new features: http://trac.roundcube.net/wiki/Changelog
* 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.

* Assume a DNS entry for each role.Guilhem Moulin2015-06-0717
| | | | | | 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.
* Decongestion potential bottlenecks on trivial_rewrite(8).Guilhem Moulin2015-06-0710
| | | | | | | | | | | | | Which might be caused by slow LDAP lookups in transport_maps. Instead, we alias each addresses for which we want a custom transport to a dedicated "dummy" domain, and use a static (CDB) transport_maps to map said domains to their transport; the receiver can then use canonical(8) to restore the original envelope recipient. Since the alias resolution is performed by cleanup(8), which can run in parallel with other instances, it should decongestion bottlenecks under heavy loads. So far only the MX:es have been decongestioned. The list manager and the MDA should be treated as well.

* Replace mktemp's deprecated -t option by --tmpdir.Guilhem Moulin2015-06-071
| | | | | But not in the installer, as busybox's implementation of mktemp didn't deprecate -t/-p.

* Fix the catch-all resolution again.Guilhem Moulin2015-06-0718
| | | | | | | | | | | | | | | | | | | | 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:
