Hiya, I've installed ISPconfig on SuSe v11 using the perfect install instructions. I'm able to send e-mail out but the e-mail bounces when I try to e-mail a user on the ISP system. The bounce message says: Code: From: Mail Delivery System <[email protected]> This is the mail system at host server1.example.com... <[email protected] (expanded from [email protected]) Is it normal to get server1.example.com when you "telnet localhost 25"? Isn't it supposed to reflect your hostname and domain? And if it is supposed to reflect your host, where do you go to change it? I'm guessing in my main.cf file but I'm not sure if this is the only place and I don't want to doink anything up. Any suggestions would be most grateful. here is my main.cf: Code: queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/lib/postfix data_directory = /var/lib/postfix mail_owner = postfix unknown_local_recipient_reject_code = 550 debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 sendmail_path = /usr/sbin/sendmail newaliases_path = /usr/bin/newaliases mailq_path = /usr/bin/mailq setgid_group = maildrop html_directory = /usr/share/doc/packages/postfix/html manpage_directory = /usr/share/man sample_directory = /usr/share/doc/packages/postfix/samples readme_directory = /usr/share/doc/packages/postfix/README_FILES inet_protocols = all biff = no mail_spool_directory = /var/mail canonical_maps = hash:/etc/postfix/canonical #virtual_alias_maps = hash:/etc/postfix/virtual virtual_alias_domains = hash:/etc/postfix/virtual relocated_maps = hash:/etc/postfix/relocated transport_maps = hash:/etc/postfix/transport sender_canonical_maps = hash:/etc/postfix/sender_canonical masquerade_exceptions = root masquerade_classes = envelope_sender, header_sender, header_recipient myhostname = server1.$mydomain program_directory = /usr/lib/postfix inet_interfaces = all masquerade_domains = #mydestination = $myhostname, localhost.$mydomain defer_transports = mynetworks_style = subnet disable_dns_lookups = no relayhost = mailbox_command = mailbox_transport = strict_8bitmime = no disable_mime_output_conversion = no smtpd_sender_restrictions = hash:/etc/postfix/access smtpd_client_restrictions = smtpd_helo_required = no smtpd_helo_restrictions = strict_rfc821_envelopes = no smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,check_relay_domains smtp_sasl_auth_enable = no smtpd_sasl_auth_enable = yes smtpd_use_tls = yes smtp_use_tls = yes alias_maps = hash:/etc/aliases mailbox_size_limit = 0 message_size_limit = 10240000 mydomain = example.com mynetworks = 127.0.0.0/8 smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_sasl_authenticated_header = yes smtpd_tls_auth_only = no 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/ virtual_maps = hash:/etc/postfix/virtusertable mydestination = /etc/postfix/local-host-names
I have similar experience (but not exactly because I am not using Suse). For your reference, I resolved the problem by: a) modifying my resolv.conf by changing it so that: nameserver 127.0.0.1 b) add the following entries in the ISPconfig DNS manager page: domain (SOA): example.com IP: [your server fixed IP] in the record page, add a hostname known as "server1" and then use the IP of your server fixed IP in the IP address field. In that case I found that the email bounce back problem no longer occurs. (Actually I've found that if one uses the true server name (e.g. www.xxxx.com instead of "server1.example.com" when you set up the server you will not get this email bounce back problem.) Hope this helps.
