Christopher A. DeFlumeri d96613b8fe minimal changeset to get things working on 18.04
@joshdata squashed pull request #1398, removed some comments, and added these notes:

* The old init.d script for the management daemon is replaced with a systemd service.
* A systemd service configuration is added to configure permissions for munin on startup.
* nginx SSL settings are updated because nginx's options and defaults have changed, and we now enable http2.
* Automatic SSHFP record generation is updated to know that 22 is the default SSH daemon port, since it is no longer explicit in sshd_config.
* The dovecot-lucene package is dropped because the Mail-in-a-Box PPA where we built the package has not been updated for Ubuntu 18.04.
* The stock postgrey package is installed instead of the one from our PPA (which we no longer support), which loses the automatic whitelisting of DNSWL.org-whitelisted senders.
* Drop memcached and the status check for memcached, which we used to use with ownCloud long ago but are no longer installing.
* Other minor changes.

Lloyd Smart 4dd4b4232a Limited ciphers to the Mozilla modern set from https://mozilla.github.io/server-side-tls/ssl-config-generator/ as requested in issue #1228. 2017-08-29 15:02:58 +01:00
Jan Schulz-Hofen 3830facf78 set dovecot vsz_limit to 1/3 of available memory (#1096)
The `default_vsz_limit` is the maximum amount of virtual memory that can be allocated. It should be set *reasonably high* to avoid allocation issues with larger mailboxes. We're setting it to 1/3 of the total available memory (physical mem + swap) to be sure.

Joshua Tauberer 73fbcd7fa3 silence all of the installing/already installed package messages on installation
Querying dpkg for each package is slow, and we have way too much output on installation because of it.

SSLv3 is already disabled in Postfix (45e93f7dcc) and Nginx (51dd2ed70b).

Joshua Tauberer a4c70f7a92 revert dovecot part of 39bca053ed because dovecot started behaving weird and I don't have time to debug it 2014-09-26 22:41:59 +00:00
Joshua Tauberer 39bca053ed add 2048 bits of DH params for nginx, postfix, dovecot
nginx/postfix use a new pre-generated dh2048.pem file. dovecot generates the bits on its own.

ssllabs.com reports that TLS_DHE ciphers went from 1024 to 2048 bits as expected. The ECDHE ciphers remain at 256 bits --- no idea what that really means. (This tests nginx only. I haven't tested postfix/dovecot.)

Joshua Tauberer 140c508ff6 increase dovecot imap_idle_notify_interval to 4 minutes
Doesn't seem like 2 minutes is a problem, but 4 minutes seems better. A little less bandwidth, possibly less battery usage (though we don't have evidence that's actually true), and the interval should be shorter than any peer timeouts that might occur due to inactivity

fixes #129

Joshua Tauberer 85bd2c8804 use the Dovecot managesieve service to manage sieve scripts
This lets roundcube's manageseive plugin do cool things like vacation responses.

Also:

* Run the spam filtering sieve script out of a global sieve file that we'll place in /etc/dovecot. It is no longer necessary to create per-user sieve files for this. Remove them with a new migration. Remove the code that created them.

* Corrects the spam script. Backslashes were double-escaped probably because this script started embedded within the bash script. Not sure how this was working until now.

this adapts work by @h8h in #103

Joshua Tauberer e713af5f5a refactor the mail setup scripts
As the scripts keep growing, it's time to split them up to
keep them understandable.

This splits mail.sh into mail-postfix.sh, mail-dovecot.sh,
and mail-users.sh, which has all of the user database-related
configurations shared by Dovecot and Postfix. Also from
spamassassin.sh the core sieve configuration is moved into
mail-dovecot.sh and the virtual transport setting is moved
into mail-postfix.sh.

Also revising one of the sed scripts in mail-dovecot to
not insert a new additional # at the start of a line each
time the script is run.
