Joshua Tauberer 06e074bd32 disable SSLv3 in dovecot now that it is known to be insecure (POODLE)
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 9d40a12f44 first pass at making readable documentation by parsing the bash scripts 2014-09-21 13:43:31 -04:00
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 023cd12e1a hide lots of unnecessary and scary output during setup 2014-07-16 09:36:56 -04:00
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.
