hi

i had mailserver and mailbox server are in two different machines. Both are having the same domain (linux.com) In my mailserver i configured all the mails to relay to my mailbox server. SMTP authentication is also enabled

The problem is I configured LDAP in my mailserver to store user information. I created all the users in the ldap database.

So when i try to send a mail to a user exists in ldap database, where as only mailbox is present in the mailbox server without user, my mail is not delivering to the recipient it was bouncing back to the sender.When i check the log i found that it was not checking the ldap database itself.

My main.cf file:

alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases, ldap:/etc/postfix/ldapaliases.cf broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 fallback_relay = $mydomain html_directory = no inet_interfaces = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = 151.2.119.150 mydomain = linux.com myhostname = experts.linux.com mynetworks = 151.2.0.0/16, 127.0.0.0/8 myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.2.10/README_FILES relay_domains = $mydestination sample_directory = /usr/share/doc/postfix-2.2.10/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination, check_relay_domains smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = $myhostname smtpd_sasl_security_options = noanonymous unknown_local_recipient_reject_code = 550

The LDIF file which i added in ldap

dn: uid=saurav,ou=solution,dc=linux,dc=com cn: Manaager sn: ganguly uid: saurav mail: saurav@linux.com description: Indian Team telephoneNumber: 012101012 userPassword: password uidNumber: 1023 homeDirectory: /home/saurav/ gidNumber: 10023 objectClass: person objectClass: top objectClass: inetOrgperson objectClass: posixAccount

This is the logs which are taken when i send mail from client to the user who has added in ldap database.
