## OpenLDAP backend special
### NEW: Support Postfix `sender_dependent_relayhost_maps`
#### Summary
Postfix setting `relayhost` allows Postfix to relay outbound emails to
specified mail server instead of connecting recipient server directly. Sender
dependent relayhost (controlled by parameter `sender_dependent_relayhost_maps`)
allows you to define per-user or per-domain relayhost, it
overrides the global `relayhost` parameter setting. Specified query tables are
searched by the envelope sender address (`user@domain.com`) and domain name
(`@domain.com`). For more details, please read Postfix document:
* Postfix parameter: [`sender_dependent_relayhost_maps`](http://www.postfix.org/postconf.5.html#sender_dependent_relayhost_maps)
* Postfix manual page: [transport(5)](http://www.postfix.org/transport.5.html)
To support `sender_dependent_relayhost_maps`, we need some modification on
iRedMail server:
* one updated iRedMail OpenLDAP schema file with new attribute: `senderRelayHost`
* two new LDAP lookup files:
* `/etc/postfix/ldap/sender_dependent_relayhost_maps_domain.cf`
* `/etc/postfix/ldap/sender_dependent_relayhost_maps_user.cf`
* one new Postfix parameter: `sender_dependent_relayhost_maps`
#### Use the latest iRedMail LDAP schema file
* On RHEL/CentOS, OpenBSD:
```
cd /tmp
wget https://bitbucket.org/zhb/iredmail/raw/default/iRedMail/samples/iredmail.schema
cd /etc/openldap/schema/
cp iredmail.schema iredmail.schema.bak
cp -f /tmp/iredmail.schema /etc/openldap/schema/
/etc/init.d/slapd restart # Use '/etc/rc.d/slapd restart' on OpenBSD
```
* On Debian/Ubuntu:
```
cd /tmp
wget https://bitbucket.org/zhb/iredmail/raw/default/iRedMail/samples/iredmail.schema
cd /etc/ldap/schema/
cp iredmail.schema iredmail.schema.bak
cp -f /tmp/iredmail.schema /etc/ldap/schema/
/etc/init.d/slapd restart
```
* On FreeBSD:
```
cd /tmp
wget https://bitbucket.org/zhb/iredmail/raw/default/iRedMail/samples/iredmail.schema
cd /usr/local/etc/ldap/schema/
cp iredmail.schema iredmail.schema.bak
cp -f /tmp/iredmail.schema /usr/local/etc/openldap/schema/
service slapd restart
```
#### Create LDAP lookup files
* On Linux/OpenBSD:
```
cd /etc/postfix/ldap/
cp -p transport_maps_domain.cf sender_dependent_relayhost_maps_domain.cf
cp -p transport_maps_user.cf sender_dependent_relayhost_maps_user.cf
perl -pi -e 's#%s#%d#g' sender_dependent_relayhost_maps_domain.cf
perl -pi -e 's#mtaTransport#senderRelayHost#g' sender_dependent_relayhost_maps*.cf
```
* On FreeBSD:
```
cd /usr/local/etc/postfix/ldap/
cp -p transport_maps_domain.cf sender_dependent_relayhost_maps_domain.cf
cp -p transport_maps_user.cf sender_dependent_relayhost_maps_user.cf
perl -pi -e 's#%s#%d#g' sender_dependent_relayhost_maps_domain.cf
perl -pi -e 's#mtaTransport#senderRelayHost#g' sender_dependent_relayhost_maps*.cf
```
#### Update Postfix settings in `/etc/postfix/main.cf`
We need to update 2 parameters in Postfix config file: `proxy_read_maps`,
`sender_dependent_relayhost_maps`.
* On __Linux/OpenBSD__, please run 2 commands below to update Postfix settings:
```
postconf -e proxy_read_maps ='$canonical_maps $lmtp_generic_maps $local_recipient_maps $mydestination $mynetworks $recipient_bcc_maps $recipient_canonical_maps $relay_domains $relay_recipient_maps $relocated_maps $sender_bcc_maps $sender_canonical_maps $smtp_generic_maps $smtpd_sender_login_maps $transport_maps $virtual_alias_domains $virtual_alias_maps $virtual_mailbox_domains $virtual_mailbox_maps $smtpd_sender_restrictions $sender_dependent_relayhost_maps'
postconf -e sender_dependent_relayhost_maps='proxy:ldap:/etc/postfix/ldap/sender_dependent_relayhost_maps_domain.cf, proxy:ldap:/etc/postfix/ldap/sender_dependent_relayhost_maps_user.cf'
```
* On __FreeBSD__, please run 2 commands below to update Postfix settings:
```
postconf -e proxy_read_maps ='$canonical_maps $lmtp_generic_maps $local_recipient_maps $mydestination $mynetworks $recipient_bcc_maps $recipient_canonical_maps $relay_domains $relay_recipient_maps $relocated_maps $sender_bcc_maps $sender_canonical_maps $smtp_generic_maps $smtpd_sender_login_maps $transport_maps $virtual_alias_domains $virtual_alias_maps $virtual_mailbox_domains $virtual_mailbox_maps $smtpd_sender_restrictions $sender_dependent_relayhost_maps'
postconf -e sender_dependent_relayhost_maps='proxy:ldap:/usr/local/etc/postfix/ldap/sender_dependent_relayhost_maps_domain.cf, proxy:ldap:/usr/local/etc/postfix/ldap/sender_dependent_relayhost_maps_user.cf'
```
Reload or restart Postfix service is required.
