Hi all ! I'm search how to configure a secondary postfix mail server. My primary server works fine, my secondary too but never deliver to primary. When the secondary receive mail, it put it in /var/mail/$USER, that's all. Code: # Security smtpd_banner = mysecondary.mailserver.com - Microsoft Exchange (5.5) biff = no disable_vrfy_command = yes smtpd_helo_required = yes # Reject unknow domain reject_unknown_recipient_domain = yes # appending .domain is the MUA's job. append_dot_mydomain = no myhostname = mysecondary.mailserver.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = domain1, domain2.... relayhost = domain1 disable_dns_lookups = yes mynetworks = 127.0.0.0/8, 192.168.0.0/24, 10.8.0.0 home_mailbox = Maildir/ mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all mailbox_command = procmail -a "$EXTENSION" transport_maps = hash:/etc/postfix/transport # Protection against Open Relay smtpd_client_restrictions = reject_rbl_client relays.ordb.org smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mx_backup, permit_mynetworks, reject_unauth_destination, reject_invalid_hostname, reject_non_fqdn_sender, reject_unknown_sender_domain, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_rhsbl_client blackhole.securitysage.com, reject_rhsbl_sender blackhole.securitysage.com, reject_rbl_client relays.ordb.org, reject_rbl_client opm.blitzed.org, reject_rbl_client list.dsbl.org, reject_rbl_client cbl.abuseat.org, reject_rbl_client dul.dnsbl.sorbs.net, check_relay_domains, permit smtpd_data_restrictions = reject_unauth_pipelining # SASL smtpd_sasl_auth_enable = yes # Pour corriger le bug de certains client (Outlook...) broken_sasl_auth_clients = yes smtpd_sasl_application_name= smtpd smtpd_sasl_security_options = noanonymous smtpd_sasl_local_domain = $myhostname # Obligatoire meme si on ne l'utilise pas smtp_sasl_password_maps = hash:/etc/sasldb2 smtp_sasl_auth_enable = no # TLS/SSL smtp_use_tls = yes smtpd_use_tls = yes smtp_tls_loglevel = 1 smtpd_tls_loglevel = 1 smtp_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/postfix/mykey.key smtpd_tls_cert_file = /etc/postfix/mykey.crt # Use Amavis content_filter = amavis:[127.0.0.1]:10024 receive_override_options = no_address_mappings I've searched for a long time, and I didn't find. The 2 MX are good DNS configured. Can someone help me please ? Thanks
Hello, Thanks for the answer. Yes the 2 MX priority differs. My primary has a 5 priority and secondary has a 10 priority. Any ideas ?
Thanks for the URL but unfortunalty it doesn't work. Uninstalled and reinstall postfix. Here is my configuration : Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. #myorigin = /etc/mailname smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. myhostname = fqdn.my.domain.name alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = fqdn.my.domain.name, my.domain.name, , localhost relayhost = nerdman.org mynetworks = 127.0.0.0/8, 10.8.0.0/24 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all smtpd_recipient_restrictions = permit_mx_backup, reject_unauth_destination, reject_invalid_hostname, reject_non_fqdn_sender, reject_unknown_sender_domain, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_rhsbl_client blackhole.securitysage.com, reject_rhsbl_sender blackhole.securitysage.com, reject_rbl_client opm.blitzed.org, reject_rbl_client list.dsbl.org, reject_rbl_client cbl.abuseat.org, reject_rbl_client dul.dnsbl.sorbs.net, reject_rbl_client zen.spamhaus.org, permit And it still deliver to /var/mail and don't forward to my primary mail server. I really don't kno why. Do you have any idea ? Thanks
Hello ! Thanks ! Now it's works better ! The mails on secondary stay in mail queue until the primary server goes up. I forgot the postmap command on my transport file ! Thanks again ! Now I encounter another problem. Like I said, the mails on the secondary go on the primary. I can see it in the logs and in the mail queue. But when they arrive to the primary, they are deleted and I don't know why. So the mail come but aren't delivred to mailbox. Someone have again a good answer to give to me ? Thanks
What's in the mail log on the primary when this happens? Do you maybe use Maildir, but the mails are delivered to mbox (or vice versa)?
Hello, I have this kind of problem log : Code: Apr 8 19:16:53 nerdman amavis[10879]: (10879-02) Passed CLEAN, [88.191.31.89] <[email protected]> -> <[email protected]>, Message-ID: <[email protected]>, mail_id: sf6m7uSvqGG6, Hits: -, queued_as: 0CDC14C06B, 153 ms Apr 8 19:16:53 nerdman postfix/smtp[7691]: BAD214C067: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=10, delays=10/0/0/0.15, dsn=2.6.0, status=sent (250 2.6.0 Ok, id=10879-02, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 0CDC14C06B) Apr 8 19:16:53 nerdman postfix/qmgr[7626]: BAD214C067: removed I have not mbox dir. So I don't really know where my email goes ! Any ideas ? Thanks
What's in /etc/postfix/main.cf on the primary (please strip out the comments)? What's the output of Code: netstat -tap ?
