Hi, please excuse my noobness, I was able to setup my server and ispconfig with this excellent guide: http://www.howtoforge.com/perfect_setup_centos5.0 I can't get Postfix to receive email but sending is fine. When i send an email to my gmail account it works great, when I send an email FROM gmail to an email user on the server, the email is returned with this message: Code: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: PERM_FAILURE: Gmail tried to deliver your message, but it was rejected by the recipient domain. The error that the other server returned was: 550 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in local recipient table. If i email web24_android @ phoneandroid.co.uk (same user) I get a different error: Code: The mail system <[email protected]>: critical OS file missing. Command output: procmail: Error while writing to "/dev/null" I tried to fix this (oops) by updating ispconfig and also rm /dev/null mknod /dev/null c 1 3 but i still get the same error, if im logged in to the shell it also tells me: Message from syslogd@ at Sun Apr 20 18:11:44 2008 ... base procmail[25303]: Error while writing to "/dev/null" when i send the email. I was also getting problems with relay denied message until I explicitly put the server name at mydestination in postfix/main.cf postconf -n 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 = $myhostname, localhost.$mydomain, localhost,phoneandroid.co.uk,base.phoneandroid.co.uk 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 some maillog output: Code: Apr 20 18:03:11 base postfix/smtpd[25178]: connect from rv-out-0708.google.com[209.85.198.240] Apr 20 18:03:12 base postfix/smtpd[25178]: NOQUEUE: reject: RCPT from rv-out-0708.google.com[209.85.198.240]: 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in local recipient table; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<rv-out-0506.google.com> Apr 20 18:03:12 base postfix/smtpd[25178]: disconnect from rv-out-0708.google.com[209.85.198.240] Apr 20 18:06:32 base postfix/anvil[25181]: statistics: max connection rate 1/60s for (smtp:209.85.198.240) at Apr 20 18:03:11 Apr 20 18:06:32 base postfix/anvil[25181]: statistics: max connection count 1 for (smtp:209.85.198.240) at Apr 20 18:03:11 Apr 20 18:06:32 base postfix/anvil[25181]: statistics: max cache size 1 at Apr 20 18:03:11 Apr 20 18:11:43 base postfix/smtpd[25297]: connect from rv-out-0708.google.com[209.85.198.246] Apr 20 18:11:43 base postfix/smtpd[25297]: B383658D56: client=rv-out-0708.google.com[209.85.198.246] Apr 20 18:11:44 base postfix/cleanup[25301]: B383658D56: message-id=<[email protected]> Apr 20 18:11:44 base postfix/qmgr[24810]: B383658D56: from=<[email protected]>, size=2017, nrcpt=1 (queue active) Apr 20 18:11:44 base procmail[25303]: Error while writing to "/dev/null" Apr 20 18:11:44 base postfix/local[25302]: B383658D56: to=<[email protected]>, relay=local, delay=0.85, delays=0.54/0.01/0/0.3, dsn=5.3.0, status=bounced (critical OS file missing.
