Dovecot will then manage the IMAP and POP3 services for the users. Tell Postfix to do this by adding the following line at the end of the file /etc/postfix/master.cf.<br /><br />nano /etc/postfix/master.cf<br />dovecot   unix  -       n       n       -       -       pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient}<br />And specify a few more options in the config file (/etc/postfix/main.cf) by executing:<br /><br />postconf -e virtual_transport=dovecot<br />postconf -e dovecot_destination_recipient_limit=1<br />Restart postfix<br /><br />service postfix restart<br />Dovecot<br />Dovecot can do several things for use. Get emails from Postfix and save them to disk, watch quotas (how much space a user may use on the servers disk), execute user-based “sieve” filter rules (can be used to put away emails to different folders), allow users to fetch emails using POP3 or IMAP. Create a user and a group just for storing emails (choose a free uid/gid):<br /><br />groupadd -g 5000 vmail<br />useradd -g vmail -u 5000 vmail -d /var/vmail -m<br />Set protocols that may be used in the dovecot configuration file:<br /><br />nano /etc/dovecot/dovecot.conf<br />protocols = imap pop3<br />Set mail location:<br /><br />nano /etc/dovecot/conf.d/10-mail.conf<br />mail_location = maildir:/var/vmail/%d/%n/Maildir<br />Configure authentication:<br /><br />nano /etc/dovecot/conf.d/10-auth.conf<br />Set authentication mechanisms to:<br /><br />auth_mechanisms = plain login<br />Comment the following line:<br /><br />#!include auth-system.conf.ext<br />And add to the bottom:<br /><br />passdb {<br />    driver = sql<br />    args = /etc/dovecot/dovecot-sql.conf<br />}<br />userdb {<br />    driver = static<br />    args = uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes<br />}<br />The “allow_all_users=yes” setting means that it is not necessary for Dovecot to check if a certain user exists. We can do that because Postfix has already ensured (in the virtual_mailbox_maps query) that the users existed before their email was handed over to Dovecot’s “deliver” agent.<br /><br />Set authentication service:<br /><br />nano /etc/dovecot/conf.d/10-master.conf<br />service auth {<br />  # auth_socket_path points to this userdb socket by default. It's typically<br />  # used by dovecot-lda, doveadm, possibly imap process, etc. Its default<br />  # permissions make it readable only by root, but you may need to relax these<br />  # permissions.

If you want to<br /># use the user@domain syntax, you might want to have a separate domain<br /># field as well.<br />#<br /># If your users all have the same uig/gid, and have predictable home<br /># directories, you can use the static userdb module to generate the home<br /># dir based on the username and domain. In this case, you won't need fields<br /># for home, uid, or gid in the database.<br />#<br /># If you prefer to use the sql userdb module, you'll want to add fields<br /># for home, uid, and gid. Here is an example table:<br />#<br /># CREATE TABLE users (<br />#     username VARCHAR(128) NOT NULL,<br />#     domain VARCHAR(128) NOT NULL,<br />#     password VARCHAR(64) NOT NULL,<br />#     home VARCHAR(255) NOT NULL,<br />#     uid INTEGER NOT NULL,<br />#     gid INTEGER NOT NULL,<br />#     active CHAR(1) DEFAULT 'Y' NOT NULL<br /># );<br /># Database driver: mysql, pgsql, sqlite<br />driver = mysql<br /># Database connection string. This is driver-specific setting.<br />#<br /># HA / round-robin load-balancing is supported by giving multiple host<br /># settings, like: host=sql1.host.org host=sql2.host.org<br />#<br /># pgsql:<br />#   For available options, see the PostgreSQL documention for the<br />#   PQconnectdb function of libpq.<br />#   Use maxconns=n (default 5) to change how many connections Dovecot can<br />#   create to pgsql.<br />#<br /># mysql:<br />#   Basic options emulate PostgreSQL option names:<br />#     host, port, user, password, dbname<br />#<br />#   But also adds some new settings:<br />#     client_flags        - See MySQL manual<br />#     ssl_ca, ssl_ca_path - Set either one or both to enable SSL<br />#     ssl_cert, ssl_key   - For sending client-side certificates to server<br />#     ssl_cipher          - Set minimum allowed cipher security (default: HIGH)<br />#     option_file         - Read options from the given file instead of<br />#                           the default my.cnf location<br />#     option_group        - Read options from the given group (default: client)<br />#<br />#   You can connect to UNIX sockets by using host: host=/var/run/mysql.sock<br />#   Note that currently you can't use spaces in parameters.<br />#<br /># sqlite:<br />#   The path to the database file.<br />#<br /># Examples:<br />#   connect = host=192.168.1.1 dbname=users<br />#   connect = host=sql.example.com dbname=virtual user=virtual password=blarg<br />#   connect = /etc/dovecot/authdb.sqlite<br />#<br />connect = host=127.0.0.1 dbname=vimbadmin user=vimbadmin password=yourpassword<br /># Default password scheme.<br />#<br /># List of supported schemes is in<br /># http://wiki2.dovecot.org/Authentication/PasswordSchemes<br />#<br />default_pass_scheme = SHA512-CRYPT<br /># passdb query to retrieve the password. It can return fields:<br />#   password - The user's password. This field must be returned.<br />#   user - user@domain from the database. Needed with case-insensitive lookups.<br />#   username and domain - An alternative way to represent the "user" field.<br />#<br /># The "user" field is often necessary with case-insensitive lookups to avoid<br /># e.g. "name" and "nAme" logins creating two different mail directories. If<br /># your user and domain names are in separate fields, you can return "username"<br /># and "domain" fields instead of "user".<br />#<br /># The query can also return other fields which have a special meaning, see<br /># http://wiki2.dovecot.org/PasswordDatabase/ExtraFields<br />#<br /># Commonly used available substitutions (see http://wiki2.dovecot.org/Variables<br /># for full list):<br />#   %u = entire user@domain<br />#   %n = user part of user@domain<br />#   %d = domain part of user@domain<br />#<br /># Note that these can be used only as input to SQL query. If the query outputs<br /># any of these substitutions, they're not touched. Otherwise it would be<br /># difficult to have eg. usernames containing '%' characters.<br />#<br /># Example:<br />#   password_query = SELECT userid AS user, pw AS password \<br />#     FROM users WHERE userid = '%u' AND active = 'Y'<br />#<br />#password_query = \<br />#  SELECT username, domain, password \<br />#  FROM mailbox WHERE username = '%u' AND domain = '%d'<br /># userdb query to retrieve the user information.

If you use a single UID and GID, and<br /># home or mail directory fits to a template string, you could use userdb static<br /># instead.

In that case you'll<br /># also have to return userdb fields in password_query prefixed with "userdb_"<br /># string. For example:<br />password_query = \<br />  SELECT username AS user, password, \<br />    homedir AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \<br />  FROM mailbox WHERE username = '%u'<br /># Query to get a list of all usernames.<br />iterate_query = SELECT username AS user FROM mailbox</blockquote><br />Adjust the driver, connect and default_pass_scheme variable to your situation.<br /><br />Set permissions:<br /><br />chgrp vmail /etc/dovecot/dovecot.conf<br />chmod g+r /etc/dovecot/dovecot.conf<br />/etc/init.d/dovecot restart<br />chown vmail.vmail /var/vmail/dovecot-deliver.log<br />chown root:root /etc/dovecot/dovecot-sql.conf<br />chmod go= /etc/dovecot/dovecot-sql.conf<br />Testing / relay<br />Get a report on your domain from http://www.pingability.com/zoneinfo.jsp.
