Hello, I have a strange problem when Postfix is sending mail with LMTP over TCP sockets to Cyrus IMAP. Cyrus IMAP is listening on port 2003 and accepting telnet connections on that port from my Postfix server. But when it comes to Postfix itself using LMTP, I see the following log messages:
mgw1 postfix/qmgr[3160]: resolve_clnt: `evgeniy.arba...@mydomain.net' -> `evgeniy.arba...@mydomain.net' -> transp=`lmtp' host=`inet:[10.1.1.100]:2003' rcpt=`evgeniy.arba...@mydomain.net' flags= class=virtual mgw1 postfix/qmgr[3160]: start sorted recipient list mgw1 postfix/qmgr[3160]: qmgr_message_sort: evgeniy.arba...@mydomain.net mgw1 postfix/qmgr[3160]: end sorted recipient list mgw1 postfix/qmgr[3160]: trigger_server_accept_fifo: trigger arrived mgw1 postfix/qmgr[3160]: master_notify: status 0 mgw1 postfix/qmgr[3160]: request: 87 (W) mgw1 postfix/qmgr[3160]: master_notify: status 1 mgw1 postfix/qmgr[3160]: qmgr_transport_select: lmtp mgw1 postfix/qmgr[3160]: qmgr_active_drain: allocate lmtp mgw1 postfix/qmgr[3160]: connect to subsystem private/lmtp: Connection refused mgw1 postfix/qmgr[3160]: warning: connect to transport lmtp: Connection refused mgw1 postfix/qmgr[3160]: qmgr_transport_throttle: transport lmtp: status: 4.3.0 reason: mail transport unavailable This is my $postconf -n config_directory = /etc/postfix disable_vrfy_command = yes inet_interfaces = all local_recipient_maps = local_transport = error:no local mail delivery mydomain = mydomain.net myhostname = mgw1.mydomain.net show_user_unknown_table_name = no smtpd_helo_required = yes smtpd_helo_restrictions = check_helo_access pcre:/etc/postf smtpd_tls_cert_file = /etc/ssl/certs/smtpd.crt smtpd_tls_key_file = /etc/ssl/private/smtpd.key smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s strict_rfc821_envelopes = yes tls_random_source = dev:/dev/urandom unknown_address_reject_code = 554 unknown_client_reject_code = 550 unknown_hostname_reject_code = 554 unverified_sender_reject_code = 554 virtual_alias_maps = ldap:/etc/postfix/virtual-aliases.cf virtual_mailbox_domains = ldap:/etc/postfix/virtual-domains virtual_mailbox_maps = ldap:/etc/postfix/virtual-addresses. virtual_transport = lmtp:inet:[10.1.1.101]:2003 This is what I have in master.cf: lmtp inet n - n - - lmtp I am sure all the LDAP lookups are working fine and I did specify lmtp in /etc/services. This is a line from cyrus.conf lmtp cmd="lmtpd" listen="[10.1.1.101]:lmtp" prefork=1 An interesting thing is that I do not see any connection attempts to the LMTP port on the Cyrus IMAP server. Can you point me out, where is the mistake? Thank you! Regards, Evgeniy
