====== Integração com o OpenLDAP ====== Instalação do modulo de integração:


root@mail:~# postconf -m | grep ldap


root@mail:~# aptitude install postfix-ldap


root@mail:~# postconf -m | grep ldap
ldap


root@mail:~# mkdir /etc/postfix/ldap

Dominios virtuais:


root@mail:~# cat /etc/postfix/ldap/vmd.cf
server_host = ldap.exemplo.org
server_port = 389
bind_dn = cn=admin,dc=exemplo,dc=org
bind_pw = 123456
search_base = dc=exemplo,dc=org
query_filter = (&(ou=%s))
result_attribute = ou
version = 3
bind = yes
timeout = 30

Mapeamento de usuários logados:


root@mail:~# cat /etc/postfix/ldap/vms.cf
server_host = ldap.exemplo.org
server_port = 389
bind_dn = cn=admin,dc=exemplo,dc=org
bind_pw = 123456
search_base = dc=exemplo,dc=org
query_filter = (&(objectClass=qmailUser)(accountStatus=A)(|(mail=%s)(mailAlternateAddress=%s)))
result_attribute = mail,mailAlternateAddress
version = 3
bind = yes
timeout = 30

Mapeamento de encaminhamento de e-mails:


root@mail:~# cat /etc/postfix/ldap/vma.cf
server_host = ldap.exemplo.org
server_port = 389
bind_dn = cn=admin,dc=exemplo,dc=org
bind_pw = 123456
search_base = dc=exemplo,dc=org
query_filter = (&(objectClass=qmailUser)(mailAlternateAddress=%s))
result_attribute = mail
version = 3
bind = yes
timeout = 30


root@mail:~# postconf -e "virtual_mailbox_domains = ldap:/etc/postfix/ldap/vmd.cf" 
root@mail:~# postconf -e "smtpd_sender_login_maps = ldap:/etc/postfix/ldap/vms.cf"
root@mail:~# postconf -e "virtual_alias_maps = ldap:/etc/postfix/ldap/vma.cf"


root@mail:~# tail -n3 /etc/postfix/master.cf
