Hi Guys. I did an Install on Cent OS 4 and all has gone very well. Every thing seams to be working fine. I have created a reseller/client and one site. All Access is good everything is working as it should, however there's just one bit I'm not too sure on. I ran an external open relay test which passed ok (it denyed sending any mail) I setup an account in Outlook 2003. Under Accounts -> more setting-> outgoing server I clicked outgoing server requires auth + log into incoming mail before sending. I can get mail ok, but when I try to send I found the following error in the log, however the mail still got sent. Dec 22 23:08:22 webserver postfix/smtpd[14883]: NOQUEUE: reject: RCPT from unknown[192.168.1.120]: 554 <[email protected]>: Relay access denied; from=<keith@????.com> to=<[email protected]> proto=ESMTP helo=<homer> however It arrived into my hotmail account shortly afterwards, what have I got setup wrong. Thanks for any help. Keith.
I could imagine the hotmail blocks emails that come from dynamic IP addresses. Does your server have a dynamic or a static IP address?
I have static IP with an SPF record so smtp to hotmail works ok, both with the ispconfig setup and my old setup. I checked the main.cf of postfix included below. I notice there is not a permit my networks setting (I did'nt configure it) it just as is then followed your install for Fedora Core 4 so either I missed some thing or its just a thing from centos. 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_maps = hash:/etc/aliases 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-2.1.5/samples readme_directory = /usr/share/doc/postfix-2.1.5/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 virtual_maps = hash:/etc/postfix/virtusertable mydestination = /etc/postfix/local-host-names Can you also confirm if I have my outlook client setup correctly. From what I'm guessing about what Ive read clients should only be able to send email once they have already auth'd using TLS. Thanks again for all your help. Keith.
I think I migth have found the problem. I enabled use same settings as my incoming mail server rather than log on to incoming mail server before sending. I'm no longer getting relay access denied any more. My only worry is why did it still allow me to send mail, unless my_permitnetworks was overriding it?
Ah, you're talking about your Outlook settings. Yes, this is correct. If you're sending emails to users that are on the server, then you don't have to authenticate. If your mynetworks setting allowed you to send without authentication to external email addresses, than you shouldn't have got the relay access denied message. I don't know why the email arrived anyway...
