Dovecot based version of the mailserver.

Browse source 
Courier and Cyrus Sasl have been removed and substituted with Dovecot which now
handle authentication for Postfix, Imap and Pop3, with support for SSL.
This allow the use of several encryption schemes for the password as well as a
single user db.
OpenDKIM keys can now be provided at the startup and will be used instead of
generating new ones (so that you don't have to change your DNS configuration).

This version builds correctly on Docker but no integration tests have been
reworked to accommodate Dovecot instead of Courier and Cyrus Sasl. As such
at present no automatic tests can be executed.

### Users
Users are managed in `postfix/accounts.cf`.
Just add the full email address and its password separated by a pipe.
Just add the full email address and its encrypted password separated by a pipe.
Example:
user1@domain.tld|mypassword
user2@otherdomain.tld|myotherpassword
user1@domain.tld|mypassword-encrypted
user2@otherdomain.tld|myotherpassword-encrypted
To generate the password you could run for example the following:
docker run --rm -ti tvial/docker-mailserver doveadm pw -s MD5-CRYPT -u user1@domain.tld
You will be asked for a password (and for a confirmation of the password). Just copy all the output string in the file `postfix/accounts.cf`.
The `doveadm pw` command let you choose between several encryption schemes for the password.
Use doveadm pw -l to get a list of the currently supported encryption schemes.

## Mailbox locations and namespaces
##
# Location for users' mailboxes. The default is empty, which means that Dovecot
# tries to find the mailboxes automatically. This won't work if the user
# doesn't yet have any mail, so you should explicitly tell Dovecot the full
# location.
#
# If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u)
# isn't enough. You'll also need to tell Dovecot where the other mailboxes are
# kept. This is called the "root mail directory", and it must be the first
# path given in the mail_location setting.
#
# There are a few special variables you can use, eg.:
#
# %u - username
# %n - user part in user@domain, same as %u if there's no domain
# %d - domain part in user@domain, empty if there's no domain
# %h - home directory
#
# See doc/wiki/Variables.txt for full list. Some examples:
#
# mail_location = maildir:~/Maildir
# mail_location = mbox:~/mail:INBOX=/var/mail/%u
# mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
#
# <doc/wiki/MailLocation.txt>
#
mail_location = maildir:/var/mail/%d/%n
# If you need to set multiple mailbox locations or want to change default
# namespace settings, you can do it by defining namespace sections.
#
# You can have private, shared and public namespaces. Private namespaces
# are for user's personal mails. Shared namespaces are for accessing other
# users' mailboxes that have been shared. Public namespaces are for shared
# mailboxes that are managed by sysadmin. If you create any shared or public
# namespaces you'll typically want to enable ACL plugin also, otherwise all
# users can access all the shared mailboxes, assuming they have permissions
# on filesystem level to do so.

# Which locking methods to use for locking mbox. There are four available:
# dotlock: Create <mailbox>.lock file. This is the oldest and most NFS-safe
# solution. If you want to use /var/mail/ like directory, the users
# will need write access to that directory.
# dotlock_try: Same as dotlock, but if it fails because of permissions or
# because there isn't enough disk space, just skip it.
# fcntl : Use this if possible. Works with NFS too if lockd is used.
# flock : May not exist in all systems. Doesn't work with NFS.
# lockf : May not exist in all systems. Doesn't work with NFS.
#
# You can use multiple locking methods; if you do the order they're declared
# in is important to avoid deadlocks if other MTAs/MUAs are using multiple
# locking methods as well. Some operating systems don't allow using some of
# them simultaneously.
#
# The Debian value for mbox_write_locks differs from upstream Dovecot. It is
# changed to be compliant with Debian Policy (section 11.6) for NFS safety.

# If dotlock exists but the mailbox isn't modified in any way, override the
# lock file after this much time.
#mbox_dotlock_change_timeout = 2 mins
# When mbox changes unexpectedly we have to fully read it to find out what
# changed. If the mbox is large this can take a long time. Since the change
# is usually just a newly appended mail, it'd be faster to simply read the
# new mails. If this setting is enabled, Dovecot does this but still safely
# fallbacks to re-reading the whole mbox file whenever something in mbox isn't
# how it's expected to be. The only real downside to this setting is that if
# some other MUA changes message flags, Dovecot doesn't notice it immediately.
# Note that a full sync is done with SELECT, EXAMINE, EXPUNGE and CHECK
# commands.
#mbox_dirty_syncs = yes
# Like mbox_dirty_syncs, but don't do full syncs even with SELECT, EXAMINE,
# EXPUNGE or CHECK commands. If this is set, mbox_dirty_syncs is ignored.
#mbox_very_dirty_syncs = no
# Delay writing mbox headers until doing a full write sync (EXPUNGE and CHECK
# commands and when closing the mailbox). This is especially useful for POP3
# where clients often delete all mails. The downside is that our changes
# aren't immediately visible to other MUAs.
