Dear All, I am using postfix + perdition + courier + ldap+ maildir (mail quota) on my mail servers. All the functions are working fine on the server except one small issue on my backend servers. I configured mail quota on the mail servers, suppose if the user quota becomes full condition 1 (working fine) if the sender mailbox and receiver mailbox existing on the same mail server the sender get a bounce back message stating that user quota is full. condition 2 (no bounce back message) if the sender and receiver mailbox existing on two different machines , it doesn't bounce back any messages.bcoz the receiver home directory is not existing on the same server
Back end server main.cf file smtpd_banner = $myhostname ESMTP mydomain = test myorigin = $mydomain inet_interfaces = all mailbox_delivery_lock = flock virtual_mailbox_lock = flock myhostname = host1.test.in mydestination = $myhostname, localhost.$mydomain,$mydomain, localhost.localdomain unknown_local_recipient_reject_code = 550 mynetworks = 127.0.0.0/8 relay_domains = $mydestination alias_maps = hash:/etc/postfix/aliases home_mailbox = Maildir/ local_recipient_maps = $virtual_mailbox_maps #local_transport=virtual local_transport=maildrop virtual_transport=maildrop maildrop_destination_recipient_limit = 1 # Virtual Domain Settings virtual_mailbox_base = / virtual_mailbox_maps = ldap:ldapsource virtual_uid_maps = static:1000 virtual_gid_maps = static:1000 virtual_minimum_uid = 1000 virtual_result_attribute = mailMessageStore # To enable Quota # Follow Maildir++ specs virtual_maildir_extended = yes # Create the maildirsize file (Vital for Courier-IMAP) virtual_create_maildirsize = yes # Bounce rather than defer when over quota virtual_overquota_bounce = yes # Ldap Mail address lookup/ Mailbox MAPS ldapsource_timeout = 60 ldapsource_server_host = 192.168.0.250 ldapsource_search_base = o=test ldapsource_server_port = 389 ldapsource_query_filter = (&(|(mail=%s)(mailAlternateAddress=%s))(!(nsAccountLock=true))) ldapsource_result_attribute = mailMessageStore ldapsource_scope = sub ldapsource_expansion_limit = 0 smtpd_recipient_restrictions = permit_mynetworks, reject_unknown_sender_domain, reject # Size Management for messages. message_size_limit = 6000000 # Performance Management default_process_limit = 200 smtpd_error_sleep_time = 0s smtp_helo_timeout = 60s smtpd_recipient_limit = 25 maximal_queue_lifetime = 2d bounce_queue_lifetime = 2d qmgr_message_active_limit = 50000 qmgr_message_recipient_limit = 50000 in_flow_delay = 0s relayhost = [192.168.0.253] header_checks = regexp:/etc/postfix/header_checks.access virtual_mailbox_domains = $mydomain, ERROR LOG relay=maildrop, delay=0, status=deferred (temporary failure. Command output: /usr/local/bin/maildrop: Unable to change to home directory. After i went through the posfix mailing list http://readlist.com/lists/postfix.org/postfix-users/13/66180.html , i added transport maps on main .cf , but no luck I added transport_maps on main.cf file transport_maps = ldap:transport # transport maps transport_timeout = 60 transport_server_host = x.x.x.x transport_search_base = o=test transport_query_filter = (&(|(mail=%s)(mailAlternateAddress=%s))(!(nsAccountLock=true))) transport_result_attribute = localmailHost transport_result_filter = smtp:%s transport_scope = sub transport_expansion_limit = 0 I am looking for a breakthrough to tackle this issue Any ideas and suggestions are welcome Best regards Paul
