* postfix: Update to recommended TLS settings.Guilhem Moulin2016-05-181
| | | | | | | | Following Viktor Dukhovni's 2015-08-06 recommendation http://article.gmane.org/gmane.mail.postfix.user/251935 (We're using stronger ciphers and protocols in our own infrastructure.)
* postfix: unset 'smtpd_tls_session_cache_database'.Guilhem Moulin2016-05-181
| | | | | | Following Viktor Dukhovni's 2015-08-06 recommendation for Postfix >= 2.11 http://article.gmane.org/gmane.mail.postfix.user/251935
* Move /etc/ssl/private/dhparams.pem to /etc/ssl/dhparams.pem and make it public.Guilhem Moulin2016-05-181
| | | | | | | | | | Ideally we we should also increase the Diffie-Hellman group size from 2048-bit to 3072-bit, as per ENISA 2014 report. https://www.enisa.europa.eu/publications/algorithms-key-size-and-parameters-report-2014 But we postpone that for now until we are reasonably certain that older client won't be left out.
* Add an ansible module 'fetch_cmd' to fetch the output of a remote command ↵Guilhem Moulin2016-05-181

|
* Fix address verification probes on the MSA.Guilhem Moulin2015-09-161
| | | | | Put all relay restrictions under smtpd_relay_restrictions and leave smtpd_recipient_restrictions empty, since we don't do DNSBL.
* Rename 'mysql_user' plugin to 'mysql_user2' to avoid name collisions.Guilhem Moulin2015-07-121
|
* Configure munin nodes & master.Guilhem Moulin2015-06-102
| | | | | Interhost communications are protected by stunnel4. The graphs are only visible on the master itself, and content is generated by Fast CGI.

|
* logjam mitigation.Guilhem Moulin2015-06-071
|
* Don't restart sympa on logrotate.Guilhem Moulin2015-06-071
| | | | This is unnecessary since it uses syslog.
* Configure the list manager (Sympa).Guilhem Moulin2015-06-0718
|
* Use $virtual_alias_domains not $virtual_mailbox_domains.Guilhem Moulin2015-06-073
| | | | | | | | | | | | | | | | | | | | | | | | | Quoting postconf(5): smtpd_reject_unlisted_recipient (default: yes) Request that the Postfix SMTP server rejects mail for unknown recipient addresses, even when no explicit reject_unlisted_recipient access restriction is specified. This prevents the Postfix queue from filling up with undeliverable MAILER-DAEMON messages. An address is always considered "known" when it matches a virtual(5) alias or a canonical(5) mapping. […] * The recipient domain matches $virtual_alias_domains but the recipient is not listed in $virtual_alias_maps. * The recipient domain matches $virtual_mailbox_domains but the recipient is not listed in $virtual_mailbox_maps, and $virtual_mailbox_maps is not null. Since we alias everything under special, "invalid", domains (mda.f.o and mailman.f.o), our $virtual_mailbox_maps was null, which led to reject_unlisted_recipient not being triggered for say, "noone@fripost.org". However, replacing $virtual_mailbox_domains with $virtual_alias_domains fits into the second point above.
* 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).
* 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).
* Tell vim the underlying filetype of templates for syntax highlighting.Guilhem Moulin2015-06-071
|
* 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 auto-create home directories when adding system users.Guilhem Moulin2015-06-071
| | | | | Unlike adduser(8), ansible's 'user' module copies skeletal configuration files even for system users (unless called with createhome=no).
* 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.
* Outgoing SMTP proxy.Guilhem Moulin2015-06-071
|
* wibbleGuilhem 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.
