    Hi,
    I was wondering if someone else has encountered this issue before whats odd its at time i get that error and the mail gets stuck on the Queue.

    This is my main:
    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 (Ubuntu)
    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
    
    readme_directory = no
    
    # TLS parameters
    smtpd_tls_cert_file = /etc/ssl/certs/server.crt
    smtpd_tls_key_file = /etc/ssl/private/server.key
    smtpd_use_tls=yes
    smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
    smtp_tls_session_cache_database = btree:${data_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.
    
    smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
    myhostname = mail.mydomain.com.co
    alias_maps = hash:/etc/aliases
    alias_database = hash:/etc/aliases
    myorigin = /etc/mailname
    mydestination = mydomain.com.co, mail.mydomain.com.co, localhost.mydomain.local, localhost
    relayhost =
    mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 192.168.0.0/24
    mailbox_size_limit = 0
    recipient_delimiter = +
    inet_interfaces = all
    inet_protocols = ipv4
    home_mailbox = Maildir/
    smtpd_sasl_type = dovecot
    smtpd_sasl_path = private/auth
    smtpd_sasl_local_domain =
    smtpd_sasl_security_options = noanonymous
    broken_sasl_auth_clients = yes
    smtpd_sasl_auth_enable = yes
    smtpd_client_connection_count_limit = 10
    smtpd_client_connection_rate_limit = 30
    disable_vrfy_command = yes
    smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
    smtp_tls_security_level = may
    smtpd_tls_security_level = may
    smtp_tls_note_starttls_offer = yes
    smtpd_tls_loglevel = 1
    smtpd_tls_received_header = yes
    sender_bcc_maps = hash:/etc/postfix/sender_bcc
    recipient_bcc_maps = hash:/etc/postfix/recipient_bcc
    virtual_alias_maps = hash:/etc/postfix/vmaps
    milter_default_action = accept
    milter_protocol = 2
    smtpd_milters = inet:localhost:8891
    non_smtpd_milters = inet:localhost:8891
    
    maximal_queue_lifetime = 1d
    
    and this is a snip of a log im getting alot of these

    Code:
        auto eth0
    
             iface eth0 inet static
    
               address 192.168.0.203
    
               netmask 255.255.255.0
    
               network 192.168.0.0
    
                gateway 192.168.0.1
               dns-nameservers 8.8.8.8
    also I was reading could be also a firewall issue but i dont think so running pfSense and check the NAT rules and everything seems good

    i can telnet to the gmail servers
    Code:
    [email protected]:~# telnet aspmx.l.google.com 25
               Trying 74.125.141.26...
              Connected to aspmx.l.google.com.
               Escape character is '^]'.
             220 mx.google.com ESMTP w131-v6si7023891vkh.19 - gsmtp

    So its very odd.

    Thank you
