    Postfix: Invalid domain


    Hey, i've set up a postfix based mail server on a public IP.
    I haven't configured a domain name yet, but i tried to test it, sending an emai to the root@[a.d.d.r] from gmail (and hotmail, but it won't let me use "[]" in the recpt) but seconds after i hit send, i get a delivery failure:

    Code:
    This is an automatically generated Delivery Status Notification
    
    Delivery to the following recipient failed permanently:
    
        root@[a.b.c.d]
    
    Technical details of permanent failure:
    PERM_FAILURE: Parse Error: Illegal To: address (invalid domain name): root@[a.b.c.d]

    I did a telnet <ip> 25, and succesfully sent an email by hand. What makes me think it's a gmail's problem, what's your oppinion on that, here's my postconf -n, if you see anything that you can advise on me, let me know. I'm new to the whole server thing... Thanks in advance!

    # postconf -n
    Code:
    [root@correo pruebas]# /usr/sbin/postconf -n
    alias_database = hash:/etc/aliases
    alias_maps = hash:/etc/aliases
    command_directory = /usr/sbin
    config_directory = /etc/postfix
    daemon_directory = /usr/libexec/postfix
    debug_peer_level = 2
    html_directory = no
    inet_interfaces = all
    local_recipient_maps = proxy:unix:passwd.byname $alias_maps
    mail_owner = postfix
    mailq_path = /usr/bin/mailq.postfix
    manpage_directory = /usr/share/man
    mydestination = $myhostname, localhost.$mydomain, localhost
    mynetworks_style = host
    newaliases_path = /usr/bin/newaliases.postfix
    queue_directory = /var/spool/postfix
    readme_directory = /usr/share/doc/postfix-2.4.5/README_FILES
    relay_domains = $mydestination
    sample_directory = /usr/share/doc/postfix-2.4.5/samples
    sendmail_path = /usr/sbin/sendmail.postfix
    setgid_group = postdrop
    unknown_local_recipient_reject_code = 550

    do your postfix logs show the connection? if so post that here

    if not then maybe gmail doesn't like sending to @[ipaddr]

    maillog shows no connection from gmail, i agree with you, it seems that gmail doesn't like raw ip addresses. thank you a lot. i'll try on a different server, to se if i get some good results.
