This document is for Baruwa's development version, may be significantly different from released versions and is a work in progress. View the current released docs here: 1.0.2.

MTA Integration

Baruwa can be integrated with the MTA to enable configuring of some MTA features from with in Baruwa. Postfix and Exim are the only MTA’s supported at the moment as Sendmail lacks native SQL support.

Postfix

At the moment the following features can be integrated

  • Relay domains
  • Transports
  • Relay recipient maps
  • Global whitelists

Relay domains

In your postfix main.cf file set:

relay_domains = mysql:/etc/postfix/mysql-relay_domains.cf

Then create the /etc/postfix/mysql-relay_domains.cf file with the following content:

user = baruwa
password = password
dbname = baruwa
query = SELECT address FROM user_addresses WHERE \
 address='%s' AND enabled=1 AND address_type=1;
hosts = 127.0.0.1

Transports

In your postfix main.cf file set:

transport_maps = mysql:/etc/postfix/mysql-transports.cf

Then create the /etc/postfix/mysql-transports.cf file with the following content:

user = baruwa
password = password
dbname = baruwa
query = SELECT CONCAT('smtp:[', mail_hosts.address, ']:', port) \
FROM mail_hosts, user_addresses WHERE user_addresses.address = '%s' AND \
user_addresses.id = mail_hosts.useraddress_id;
hosts = 127.0.0.1

Relay recipient maps

In your postfix main.cf file set:

relay_recipient_maps = mysql:/etc/postfix/mysql-relay_recipients.cf

Then create the /etc/postfix/mysql-relay_recipients.cf file with the following content:

user = baruwa
password = password
dbname = baruwa
query = SELECT 1 FROM user_addresses WHERE address='%s' AND address_type=2 \
UNION SELECT 1 FROM auth_user WHERE username = '%s' OR email = '%s' \
hosts = 127.0.0.1

Global Whitelist

In your postfix main.cf file set:

whitelist_policy = check_client_access mysql:/etc/postfix/mysql-global_lists.cf
smtpd_recipient_restrictions = whitelist_policy

Then create the /etc/postfix/mysql-global_lists.cf with the following content:

user = baruwa
password = password
dbname = baruwa
query = SELECT CONCAT('PERMIT') FROM lists WHERE from_address='%s' AND list_type=1 \
UNION SELECT CONCAT('REJECT') FROM lists WHERE from_address='%s' AND list_type=2;
hosts = 127.0.0.1

Exim

At the moment the following features can be integrated.

  • Route Data
  • Relay domains

Route Data

You can use the following route_data option in your routers used to deliver the cleaned mail:

route_data = ${lookup mysql {SELECT GROUP_CONCAT(CONCAT(mail_hosts.address,\
                '::',mail_hosts.port) SEPARATOR ':') a FROM mail_hosts, \
                user_addresses WHERE useraddress_id=user_addresses.id AND \
                user_addresses.address = '${quote_mysql:$domain}' AND \
                mail_hosts.enabled = 1 AND user_addresses.enabled = 1}}

Relay domains

Use the following domain list in your acl’s:

domainlist relay_sql_domains = mysql;SELECT address FROM user_addresses WHERE \
address_type=1 AND enabled=1 AND address='${quote_mysql:$domain}';
