Hi, I followed the Fedora Core 5 installation guide, and installed ISPconfig. Everything seems to be fine (Everyone recieves and sends email), but For each email recieved, there is also an email with: undelivered mail returned to sender: localhost.localdomain.sabi.ws loops back to myself I had to change the soft_bounce to "yes" in the main.cf file for postfix, otherwise, It kept looping back filling up the mail boxes. Below is the configuration information, please let me know if anything else is needed ... :-( This is my main.cf file (after removing all of the comments): soft_bounce = yes queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/libexec/postfix mail_owner = postfix inet_interfaces = all unknown_local_recipient_reject_code = 550 alias_database = hash:/etc/aliases debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin xxgdb $daemon_directory/$process_name $process_id & sleep 5 sendmail_path = /usr/sbin/sendmail.postfix newaliases_path = /usr/bin/newaliases.postfix mailq_path = /usr/bin/mailq.postfix setgid_group = postdrop html_directory = no manpage_directory = /usr/share/man sample_directory = /usr/share/doc/postfix-2.2.8/samples readme_directory = /usr/share/doc/postfix-2.2.8/README_FILES smtpd_sasl_local_domain = smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_tls_auth_only = no smtp_use_tls = yes smtpd_use_tls = yes smtp_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom home_mailbox = Maildir/ mailbox_command = virtual_maps = hash:/etc/postfix/virtusertable mydestination = /etc/postfix/local-host-names The /etc/postdix/local-host-names are: (The server identifies itself as server.sabi.ws) localhost server.sabi.ws localhost.server.sabi.ws localhost.sabi.ws localhost.localdomain www.mysmallhome.com www.ezwebsite.ca www.gladysarts.com www.orca-art.com mysmallhome.com ezwebsite.ca gladysarts.com orca-art.com
Please add: localhost.localdomain.sabi.ws at the end of the file /etc/postfix/local-host-names and restart postfix.
