Hi All, I'm having some trouble with PostFix on my server. I set up a simple email address: [email protected] Initially, I was able to send email from mail.yahoo.com and receive it successfully at this address. However, when I submitted my email address to other websites ( for confirmation of email purposes, similar to a forum email confirmation ) the emails did not come. Ever since, I've been playing with Postfix, and just now the a few of the emails arrived from Paypal.com (5 hours later), a service I was attempting to subscribe to. Now, though, emails from yahoo DO NOT come. Here's my /var/log/maillog for the emails that arrived 5 hours late: Code: Jan 18 21:01:02 cayenne postfix/smtpd[4218]: connect from outbound2.den.paypal.com[216.113.188.112] Jan 18 21:01:02 cayenne postfix/smtpd[3965]: disconnect from unknown[58.60.175.218] Jan 18 21:01:02 cayenne postfix/smtpd[4218]: 766A1F805E: client=outbound2.den.paypal.com[216.113.188.112] Jan 18 21:01:02 cayenne postfix/cleanup[4311]: 766A1F805E: message-id=<[email protected]> Jan 18 21:01:02 cayenne postfix/qmgr[3749]: 766A1F805E: from=<[email protected]>, size=15705, nrcpt=1 (queue active) Jan 18 21:01:03 cayenne sendmail[4317]: n0J213Hv004317: from=web434_7onet, size=110, class=0, nrcpts=1, msgid=<[email protected]>, relay=web434_7onet@localhost Jan 18 21:01:03 cayenne postfix/smtpd[3965]: connect from localhost.localdomain[127.0.0.1] Jan 18 21:01:03 cayenne postfix/smtpd[3965]: setting up TLS connection from localhost.localdomain[127.0.0.1] Jan 18 21:01:03 cayenne postfix/smtpd[3965]: TLS connection established from localhost.localdomain[127.0.0.1]: TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits) Jan 18 21:01:03 cayenne sendmail[4317]: STARTTLS=client, relay=[127.0.0.1], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 Jan 18 21:01:03 cayenne postfix/smtpd[3965]: 0ECCEF8062: client=localhost.localdomain[127.0.0.1], [email protected] Jan 18 21:01:03 cayenne postfix/cleanup[4311]: 0ECCEF8062: message-id=<[email protected]> Jan 18 21:01:03 cayenne postfix/qmgr[3749]: 0ECCEF8062: from=<[email protected]>, size=773, nrcpt=1 (queue active) Jan 18 21:01:03 cayenne sendmail[4317]: n0J213Hv004317: to=admispconfig@localhost, ctladdr=web434_7onet (10432/10434), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30110, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (Ok: queued as 0ECCEF8062) Jan 18 21:01:03 cayenne postfix/smtpd[3965]: disconnect from localhost.localdomain[127.0.0.1] Jan 18 21:01:03 cayenne postfix/local[4312]: 766A1F805E: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=0.73, delays=0.59/0.01/0/0.13, dsn=2.0.0, status=sent (delivered to command: /usr/bin/procmail -f-) Jan 18 21:01:03 cayenne postfix/qmgr[3749]: 766A1F805E: removed Jan 18 21:01:03 cayenne postfix/local[4319]: 0ECCEF8062: to=<[email protected]>, relay=local, delay=0.08, delays=0.05/0.01/0/0.02, dsn=2.0.0, status=sent (delivered to command: /usr/bin/procmail -f-) Jan 18 21:01:03 cayenne postfix/qmgr[3749]: 0ECCEF8062: removed And my Main.cf: Code: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 home_mailbox = Maildir/ html_directory = no inet_interfaces = all mail_owner = postfix mailbox_command = mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = /etc/postfix/local-host-names mynetworks = 127.0.0.0/8 newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_tls_note_starttls_offer = yes smtp_use_tls = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_auth_only = no smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s smtpd_use_tls = yes tls_random_source = dev:/dev/urandom unknown_local_recipient_reject_code = 550 Things I've already checked: 1. Server not on Black List 2. Httpd, Named, and Ispconfig_server are all up and functioning 3. Postfix and dovecot are up and functioning 4. I used the same config settings on another server without issues 5. Maildir is selected in Server->Settings 6. LocalServer is selected for www.mydomain.net 7. LocalServer is selected for co-domain mydomain.net 8. Entries for mydomain are present in virtusertable 9. Local-host-names file appears to be intact, but not 100% sure if the correct hostnames are specified... I think it may be a DNS problem - OR - something to do with the mail queue, but the fact that the message registers 5-6 hours late suggests a DNS or address issue... Thanks for any help!
Yes, DNS + Host Hi Falko, Thanks for your reply. Yes, the problem was DNS propagation. I thought it would be relatively fast, but in reality it took about 24 hours. Also, my server recently changed hosting companies, so the domain used as the server's hostname was no longer active. As a result, I had to reconfigure ISPconfig DNS, plus enter a new hostname for the server using Code: hostname 123.myserver.net command from the shell. Thanks as always for your replies!
