Basic stuff for getting various personal servers running.

Fill in a mailserver using the example-com inventory as an example. Populate files/mailserver.crt and files/mailserver.key with the server certificate and key.

To add a new user and password, update /etc/dovecot/users, which should be permissioned 640 dovecot:dovecot, with a username and password in the following format (ensuring that user matches a unix user on the system):

#user:password:uid:gid:(gecos):home:(shell):extra_fields

Get the password by running doveadm pw, and fill in relevant information, e.g.:

linda:{CRAM-MD5}63f73fd5c7d215dc84b3f55be69da501de920dd1a3db77968dd12e2880a037c3:500:500::/home/linda:

A few notes on configuration:

1. spamassassin and dovecot sieve are installed and enabled, but will need some configuration. I chose not to include a default dovecot sieve file because I’d like to leave this up to personal preferences, but I would recommend putting a file at ~/.dovecot.sieve with the following, to filter things marked as spam into a spam folder:

require "fileinto";

if allof (
   header :contains "X-Spam-Status" "YES",
   not header :contains "X-Spam-Status" "No" )
{
        fileinto "spam";
}

2. while spamassassin will update daily from the current setup here, it may be worthwhile to use sa-learn --spam on a folder of spam uncaught by spamassassin, and run sa-learn --ham on a folder like your inbox, to further train the filter.
