Hello, I've a question concerning the configuration of postfix. I have a server running on SLES 10 where I configured postfix. This server should be a relay host and should also buffer mails if someone will send lots of mails like newsletters for example. The access to this server will be controlled through an ACL. So I'm able to send mails to internal addresses over this new server to our mail server. But if I try to send a mail to an external address like gmx.net, gmail.com or yahoo.com I've got the error 554 Relay access denied. So what I want to achieve is that postfix will relay ALL mails (internal and external) to our mail server when the client/application has the permission to send mails. Here is my config: /etc/postfix/main.cf (without comments) Code: queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/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 xxgdb $daemon_directory/$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 = g99la004 program_directory = /usr/lib/postfix inet_interfaces = 223.99.214.221 ::1 masquerade_domains = smtptest.de mydestination = $mydomain defer_transports = mynetworks_style = class disable_dns_lookups = yes relayhost = [internetmailgateway] relay_domains = $mydomain, domain1.de, domain2.de, domain3.de mailbox_command = mailbox_transport = strict_8bitmime = no disable_mime_output_conversion = no smtpd_sender_restrictions = hash:/etc/postfix/access smtpd_client_restrictions = smtpd_banner = $myhostname - powered by $mail_name smtpd_helo_required = no smtpd_helo_restrictions = strict_rfc821_envelopes = no smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination smtp_sasl_auth_enable = no smtpd_sasl_auth_enable = no smtpd_use_tls = no smtp_use_tls = no alias_maps = hash:/etc/aliases mailbox_size_limit = 0 message_size_limit = 10240000 output of the command postconf -n Code: alias_maps = hash:/etc/aliases biff = no canonical_maps = hash:/etc/postfix/canonical command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/lib/postfix debug_peer_level = 2 defer_transports = disable_dns_lookups = yes disable_mime_output_conversion = no html_directory = /usr/share/doc/packages/postfix/html inet_interfaces = 223.99.214.221 ::1 inet_protocols = all mail_owner = postfix mail_spool_directory = /var/mail mailbox_command = mailbox_size_limit = 0 mailbox_transport = mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man masquerade_classes = envelope_sender, header_sender, header_recipient masquerade_domains = smtptest.de masquerade_exceptions = root message_size_limit = 10240000 mydestination = $mydomain myhostname = g99la004 mynetworks_style = class newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/packages/postfix/README_FILES relay_domains = $mydomain, domain1.de, domain2.de, domain3.de relayhost = [internetmailgateway] relocated_maps = hash:/etc/postfix/relocated sample_directory = /usr/share/doc/packages/postfix/samples sender_canonical_maps = hash:/etc/postfix/sender_canonical sendmail_path = /usr/sbin/sendmail setgid_group = maildrop smtp_sasl_auth_enable = no smtp_use_tls = no smtpd_banner = $myhostname - powered by $mail_name smtpd_client_restrictions = smtpd_helo_required = no smtpd_helo_restrictions = smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination smtpd_sasl_auth_enable = no smtpd_sender_restrictions = hash:/etc/postfix/access smtpd_use_tls = no strict_8bitmime = no strict_rfc821_envelopes = no transport_maps = hash:/etc/postfix/transport unknown_local_recipient_reject_code = 550 virtual_alias_domains = hash:/etc/postfix/virtual virtual_alias_maps = hash:/etc/postfix/virtual The error I've got when I try to send a mail to gmx or yahoo within /var/log/mail: part out of mail.info Code: NOQUEUE: reject: RCPT from server.domain[IP-Address]: 554 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<domain4.com> I hope you can tell me what's wrong... Best regards,
Either set up SMTP-AUTH on the mail server and enable "Server requires authentication." in your email client, or add your client's IP address/subnet to the mynetworks paramater in /etc/postfix/main.cf (comment out mynetworks_style then). Restart Postfix afterwards.
I was having that exact problem earlier, and discovered that same solution. I added my network IP and everything started to work better, however i now cannot seem to resolve MX records! As a result i seem to send mails into postfix, but get nothing out the other side, or anything to tell me there was an error! Thank the lord for the log files, but all they can tell me is they couldn;t find an MX record. When I dig MX hotmail.co.uk i get nothing, but when i check it on www.dnsstuff.com i find what i expected! any ideas?
falco: OK, i should have thought of that!!! The only nameserver entry was the IP of my router, which seems to work fine with all but MX records! I added in an extra nameserver, using the one my router got from my ISP, now it works fine!!! Thanks
Hi falko, thanks for your help. I have changed the variable mynetworks as you suggested and after restarting postfix I was able to send mails even to external addresses. One question concerning smtp_auth - is this just to set these two variables to "yes"? Code: smtp_sasl_auth_enable = no smtpd_sasl_auth_enable = no or is there more to do? the service saslauthd is running at the moment.
Take a look at chapter 7 on http://www.howtoforge.com/perfect_setup_opensuse_10.2_p6 . It shows what you must do to enable SMTP-AUTH.
