・・・
##
## Mailbox locations and namespaces
##

# Location for users' mailboxes. This is the same as the old default_mail_env
# setting. The default is empty, which means that Dovecot tries to find the
# mailboxes automatically. This won't work if the user doesn't have any mail
# yet, 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 /usr/share/doc/dovecot-common/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

  # Password database is used to verify user's password (and nothing more).
  # You can have multiple passdbs and userdbs. This is useful if you want to
  # allow both system users (/etc/passwd) and virtual users to login without
  # duplicating the system users into virtual database.
  #
  # <doc/wiki/PasswordDatabase.txt>
  #
  # By adding master=yes setting inside a passdb you make the passdb a list
  # of "master users", who can log in as anyone else. Unless you're using PAM,
  # you probably still want the destination user to be looked up from passdb
  # that it really exists. This can be done by adding pass=yes setting to the
  # master passdb. <doc/wiki/Authentication.MasterUsers.txt>

  # Users can be temporarily disabled by adding a passdb with deny=yes.
  # If the user is found from that database, authentication will fail.
  # The deny passdb should always be specified before others, so it gets
  # checked first. Here's an example:

  passdb passwd-file {
    # File contains a list of usernames, one per line
    #args = /etc/dovecot.deny
    #deny = yes
    args = /etc/dovecot/passwd
  }

  # PAM authentication. Preferred nowadays by most systems. 
  # Note that PAM can only be used to verify if user's password is correct,
  # so it can't be used as userdb. If you don't want to use a separate user
  # database (passwd usually), you can use static userdb.
  # REMEMBER: You'll need /etc/pam.d/dovecot file created for PAM
  # authentication to actually work. <doc/wiki/PasswordDatabase.PAM.txt>
  passdb pam {
    # [blocking=yes] [session=yes] [setcred=yes]
    # [cache_key=<key>] [<service name>]
    #
    # By default a new process is forked from dovecot-auth for each PAM lookup.
    # Setting blocking=yes uses the alternative way: dovecot-auth worker
    # processes do the PAM lookups.
    #
    # session=yes makes Dovecot open and immediately close PAM session. Some
    # PAM plugins need this to work, such as pam_mkhomedir.
    #
    # setcred=yes makes Dovecot establish PAM credentials if some PAM plugins
    # need that. They aren't ever deleted though, so this isn't enabled by
    # default.
    #
    # cache_key can be used to enable authentication caching for PAM
    # (auth_cache_size also needs to be set). It isn't enabled by default
    # because PAM modules can do all kinds of checks besides checking password,
    # such as checking IP address. Dovecot can't know about these checks
    # without some help. cache_key is simply a list of variables (see
    # /usr/share/doc/dovecot-common/wiki/Variables.txt) which must match for
    # the cached data to be used. Here are some examples:
    #   %u - Username must match. Probably sufficient for most uses.
    #   %u%r - Username and remote IP address must match.
    #   %u%s - Username and service (ie. IMAP, POP3) must match.
    # 
    # If service name is "*", it means the authenticating service name
    # is used, eg. pop3 or imap (/etc/pam.d/pop3, /etc/pam.d/imap).
    #
    # Some examples:
    #   args = session=yes *
    #   args = cache_key=%u dovecot
    #args = dovecot

Dovecotユーザの作成

# useradd -u 10000 -s /bin/false vmailmgr
# mkdir /home/dovecot
# mkdir /home/dovecot/mydomain.com

adminというメールアカウントを作成する場合は以下のようにします。

# mkdir /home/dovecot/mydomain.com/admin

パーミッションを変更します。

# chown -R vmailmgr.vmailmgr /home/dovecot

パスワードファイルを作成します

# vi /etc/dovecot/passwd
user1@mydomain.com:{CRAM-MD5}ace37ad159394e0038338b4e4dcd9481dc691401420b6a3d3ab0777ad9563491:10000:100000::/home/dovecot/mydomain.com/user1/::/sbin/nologin

バーチャルメールボックスの設定

/etc/postfix/main.cfでvirtual_mailbox_mapsを記述しましたが、そのファイルを編集します。

# vi /etc/postfix/vmailbox

メールアドレスとMaildirのディレクトリを記述します。

admin@mydomain.com mydomain.com/admin/Maildir/

上記設定で、admin@mydomain.comのMaildirは、

/home/dovecot/mydomain.com/admin/Maildir/

になります。
下記コマンドで設定が反映されます。

# postmap /etc/postfix/vmailbox

バーチャルエイリアスマップスの設定

/etc/postfix/main.cfでvirtual_alias_mapsを記述しましたが、そのファイルを編集します。
バーチャルエイリアスを使用しない場合でも、ファイルが存在しないと正常に動作しないため、空ファイルを作成します。

# touch /etc/postfix/virtual

下記コマンドで、設定が反映されます。

# postmap /etc/postfix/virtual
# strings /etc/postfix/virtual

この後、dovecotを再読み込みし動作を確認します。

# /etc/init.d/dovecot restart
