Hi all, thank you for taking the time to help me on my issue(s) here since im desperate to solve this. My mail server (solaris 10) running Postfix 2.8.9 with dovecot and spamassassin had an issue sending out email (local nor internet). It's been running for quite awhile but i did changed something (i did'nt know which conf) to make it more secure but for stupid of me i didnt make any back-up before then. it's been 3 days since i scratching my head with no avail. perhaps you could point me out to the light. here are my configuration; postconf -f soft_bounce = no queue_directory = /var/opt/csw/spool/postfix command_directory = /opt/csw/sbin daemon_directory = /opt/csw/libexec/postfix data_directory = /var/opt/csw/lib/postfix mail_owner = postfix myhostname = xx.xx.com mydomain = xx.com myorigin = $mydomain inet_interfaces = all mydestination = $myhostname, xx.com, localhost.$mydomain, localhost, $mydomain unknown_local_recipient_reject_code = 550 mynetworks_style = host #relay_domains = relayhost = alias_maps = hash:/etc/postfix/aliases alias_database = hash:/etc/postfix/aliases recipient_delimiter = + home_mailbox = Maildir/ mail_spool_directory = /var/spool/mail mailbox_command = /opt/csw/libexec/dovecot/deliver mailbox_transport = dovecot virtual_transport = dovecot dovecot_destination_recipient_limit=1 smtpd_banner = $myhostname ESMTP $mail_name debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/opt/csw/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 sendmail_path = /opt/csw/sbin/sendmail mailbox_size_limit=524288000 message_size_limit=52428800 newaliases_path = /opt/csw/bin/newaliases mailq_path = /opt/csw/bin/mailq setgid_group = postdrop virtual_minimum_uid = 100 fallback_transport = virtual disable_vrfy_command = yes smptd_recipient_restrictions = permit_mynetworks, reject_rbl_client sbl.spamhaus.org, reject_rbl_client bl.spamcop.net, reject_non_fqdn_sender, reject_unknown_sender_domain, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_pipelining, reject_unauth_destination, reject_unknown_client, check_policy_service unixrivate/policy, reject_non_fqdn_recipient owner_request_special = no smtpd_sasl_type = dovecot smtpd_sasl_path = /var/opt/csw/spool/postfix/private/auth smtpd_sasl_local_domain = mcbridesurgicalcenter.com smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_sasl_authenticated_header = yes smtpd_use_tls = yes smtpd_tls_cert_file=/opt/csw/ssl/certs/dovecot.pem smtpd_tls_key_file=/opt/csw/ssl/private/dovecot.pem tls_random_source = /dev/urandom smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache smtpd_tls_security_level = may smtpd_tls_received_header = yes smtpd_tls_auth_only = no smtpd_tls_loglevel = 1 smtp_tls_note_starttls_offer = yes smtpd_tls_session_cache_timeout = 3600s smtpd_sender_restrictions = reject_unknown_sender_domain, check_sender_access hash:/etc/opt/csw/postfix/blacklist alternate_config_directories=/etc/opt/csw/postfix master.cf smtp inet n - n - - smtpd -o content_filter=spamfilt submission inet n - n - - smtpd -o syslog_name=postfix/submission -o smtpd_tls_security_level=encrypt -o smtpd_tls_wrappermode=no -o smtpd_client_restrictions=permit_mynetworks, reject -o smtpd_sasl_type=dovecot -o smtpd_sasl_path=/var/opt/csw/spool/postfix/private/auth -o smtpd_sasl_security_options=noanonymous -o smtpd_sender_login_maps=hash:/etc/postfix/virtual -o smtpd_sender_restrictions=reject_sender_login_mismatch -o smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject -o milter_macro_daemon_name=ORIGINATING pickup fifo n - n 60 1 pickup cleanup unix n - n - 0 cleanup qmgr fifo n - n 300 1 qmgr #qmgr fifo n - n 300 1 oqmgr tlsmgr unix - - n 1000?

Any thought are welcome.
