    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,

    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

    Do the priorities of the MX records differ?

    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)?

    What's in /etc/postfix/main.cf on the primary (please strip out the comments)? What's the output of
    Code:
    netstat -tap
    ?
