Postfix configuration for use with PostfixAdmin ----------------------- Your installation of Postfix MUST support either MySQL or Postgres lookup tables. You can verify that with 'postconf -m' Its generally recommended to use proxy as well (which should also appear in postconf -m) Three main.cf variables are involved: virtual_mailbox_domains = proxy:mysql:/etc/postfix/sql/mysql_virtual_domains_maps.cf virtual_alias_maps = proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_maps.cf, proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_domain_maps.cf, proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_domain_catchall_maps.cf virtual_mailbox_maps = proxy:mysql:/etc/postfix/sql/mysql_virtual_mailbox_maps.cf, proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_domain_mailbox_maps.cf # Additional for quota support virtual_create_maildirsize = yes virtual_mailbox_extended = yes virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf virtual_mailbox_limit_override = yes virtual_maildir_limit_message = Sorry, the user's maildir has overdrawn his diskspace quota, please try again later. virtual_overquota_bounce = yes Where you chose to store the .cf files doesn't really matter, but they will have database passwords stored in plain text so they should be readable only by user postfix, or in a directory only accessible to user postfix. This isn't necessarily all you need to do to Postfix to get up and running. Also, additional changes are needed for the vacation autoreply features. ------------------------- Contents of the files These are examples only, you will likely have to and want to make some cumtomizations. You will also want to consider the config.inc.php settings for domain_path and domain_in_mailbox. These examples use values of domain_path=YES and domain_in_mailbox=NO mysql_virtual_alias_maps.cf: user = postfix password = password hosts = localhost dbname = postfix query = SELECT goto FROM alias WHERE address='%s' AND active = '1' #expansion_limit = 100 mysql_virtual_alias_domain_maps.cf: user = postfix password = password hosts = localhost dbname = postfix query = SELECT goto FROM alias,alias_domain WHERE alias_domain.alias_domain = '%d' and alias.address = CONCAT('%u', '@', alias_domain.target_domain) AND alias.active = 1 AND alias_domain.active='1' (Note: PostgreSQL does not have a concat() function, instead use e.g. .... alias.address = '%u' || '@' || alias_domain.target_domain AND ....) mysql_virtual_alias_domain_catchall_maps.cf: # handles catch-all settings of target-domain user = postfix password = password hosts = localhost dbname = postfix query = SELECT goto FROM alias,alias_domain WHERE alias_domain.alias_domain = '%d' and alias.address = CONCAT('@', alias_domain.target_domain) AND alias.active = 1 AND alias_domain.active='1' (See above note re Concat + PostgreSQL) mysql_virtual_domains_maps.cf: user = postfix password = password hosts = localhost dbname = postfix query = SELECT domain FROM domain WHERE domain='%s' AND active = '1' #query = SELECT domain FROM domain WHERE domain='%s' #optional query to use when relaying for backup MX #query = SELECT domain FROM domain WHERE domain='%s' AND backupmx = '0' AND active = '1' #expansion_limit = 100 mysql_virtual_mailbox_maps.cf: user = postfix password = password hosts = localhost dbname = postfix query = SELECT maildir FROM mailbox WHERE username='%s' AND active = '1' #expansion_limit = 100 mysql_virtual_alias_domain_mailbox_maps.cf: user = postfix password = password hosts = localhost dbname = postfix query = SELECT maildir FROM mailbox,alias_domain WHERE alias_domain.alias_domain = '%d' and mailbox.username = CONCAT('%u', '@', alias_domain.target_domain) AND mailbox.active = 1 AND alias_domain.active='1' (See above note re Concat + PostgreSQL) # For quota support mysql-virtual-mailbox-limit-maps.cf: user = postfix password = password hosts = localhost dbname = postfix query = SELECT quota FROM mailbox WHERE username='%s' AND active = '1' ------------------------- More information - HowTo docs that use PostfixAdmin http://postfix.wiki.xs4all.nl/index.php?title=Virtual_Users_and_Domains_with_Courier-IMAP_and_MySQL http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL
