    Hy,

    I followed this (Virtual Users And Domains With Postfix, Courier And MySQL (Ubuntu 7.10)) tutorial for an email server. I did stept by step, with no errors. The only changes I have made are regarding ip's and domains.

    The server works fine, I can receive email, I also can send emails but only for the users of my domains. If i try to sent a message to [email protected] i get this error status=deferred (delivery temporarily suspended: connect to gsmtp183.google.com[64.233.183.27]: Connection timed out).

    The server is behind a router, and i have forwarded port 25 and 110, 143 to the server. Also to mention that I have tested another email server which works fine on the same connection, so the provider didn't block port 25.

    i'll give you the main.conf of teh server and some lines from the log:

    main.conf:

    If your internet connection has a dynamic IP address, then it will be blocked by most email providers like google or hotmail. You should consider to relay your emails trogh the smtp server of your internet provider instead.

    Hy,
    thanks for the quick answer.

    I have a static IP.

    Maybe this can help. I found this error in the postfix queue list from postqueue -p

    3101 Fri Dec 28 15:52:02 [email protected]
    (Host or domain name not found. Name service error for name=localhost type=A: Host not found)
    ********@gmail.com

    I have a similar error for each mail that i tried to sent. :mad:

    Please advise......

    Thank you in advance

    Please check if your server is blacklisted: http://www.mxtoolbox.com/blacklists.aspx

    What's in /etc/hosts?

    Here is my /etc/hosts

    The server is behind a DSL router, in which i have set as a "virtual server" the address of the actual server.

    Thank you

    Please try this:
    Code:
    127.0.0.1 localhost.localdomain localhost
    192.168.123.118 mail.domain.ro mail [COLOR="Red"]domain.ro[/COLOR]
    
    # The following lines are desirable for IPv6 capable hosts
    ::1 ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters

    PostFix behind router

    Hi All
    I have same problem as You "running PostFix Mail Server behind router "
    I can receive mail from outside but I can`t send them out I read lot of forums and lot web sides I did not found solution for this problem
    but I know for sure this is because of router
    If I connect server directly to DSL modem everything is working perfectly :)
    but not if is behind router even I open port 25 to mail server :mad:
    do anybody know haw to set up PostFix do deal with this, or any other suggestion? :confused:
    Thanks Chris.

    Postfix issue: Relay access denied and problem with sending mails

    Hi,
    I've just installed postfix and popa3d - debian packages.

    1. When I try to send an e-mail from Gmail account to me:
    I'm getting error:
    Code:
    Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 5.7.1 <[email protected]>: Relay access denied (state 14).
    2. When I try to send an e-mail from Postfix to Gmail it normally, go out, but I am not getting this e-mail on my Gmail account.

    My main.cf is:
    Code:
    myorigin = /etc/mailname # domain.com
    
    smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
    biff = no
    
    append_dot_mydomain = no
    
    readme_directory = no
    
    
    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:${data_directory}/smtpd_scache
    smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
    
    myhostname = my computer static ISP hostname
    mydomain = domain.com
    mydestination = $myhostname
    mynetworks = 192.168.0.0/24
    inet_interfaces = all
    
    alias_maps = hash:/etc/aliases
    alias_database = hash:/etc/aliases
    
    disable_dns_lookups = yes
    
    mailbox_command = procmail -a "$EXTENSION"
    mailbox_size_limit = 0
    recipient_delimiter = +
    What should I do?
