* Add note how to test SASL EXTERNAL authentication via TLS.Guilhem Moulin2015-06-071
|
* typoGuilhem Moulin2015-06-071
|
* More logcheck-database tweaks.Guilhem Moulin2015-06-073
|
* Generate the DKIM key on the outgoing instance only.Guilhem Moulin2015-06-071
|
* Fix a corner case in reserved-alias.pl.Guilhem Moulin2015-06-071
| | | | | 'if $l' is false when $l is 0, while 0@example.org is a perfectly valid address.
* Configure SyncRepl (OpenLDAP replication) and related ACLs.Guilhem Moulin2015-06-075
| | | | | | | | | | | | | | | | | | | | | | | 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 Moulin2015-06-074
| | | | Also, it's now possible to reuse an existing private key (with -f).
* Add ability to chmod, chown and set the key usage in genkeypair.Guilhem Moulin2015-06-071
|
* Enable zero-copy updates to the LDAP directory.Guilhem Moulin2015-06-073
|
* Increase the timeout in the smtpd waiting for the reinjection from amavis.Guilhem Moulin2015-06-073
| | | | | | | | 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 Moulin2015-06-0710
|
* Reload Postfix upon configuration change, but don't restart it.Guilhem Moulin2015-06-0714
| | | | | | (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 Moulin2015-06-075
| | | | | | 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 .
* Loopia's maximum length for TXT records is 255 chars.Guilhem Moulin2015-06-073
| | | | So unfortunately we can't fit a 2048-bits RSA key.

|
* 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.

* Log SASL usernames for longer, but don't include mail.log into syslog.Guilhem Moulin2015-06-075

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 :-)
