    I followed the guide for "the perfect server ubuntu 11.10"
    http://www.howtoforge.com/perfect-server-ubuntu-11.10-ispconfig-3

    The system runs great with 1 small issue.. and it could be a user issue :)

    I set up a user account to send/receive email. I then set up thunderbird to send/recv I am able to receive the email fine, but sending it gives error that it times out. So my question is... what port is this guide using and what type of authentication should I be using?

    thanks

    not sure if this helps..



    pwcheck_method: saslauthd
    mech_list: plain login
    allow_plaintext: true
    auxprop_plugin: mysql
    sql_hostnames: 127.0.0.1
    sql_user: ispconfig
    sql_passwd: [omitted]
    sql_database: dbispconfig
    sql_select: select password from mail_user where login = '%u'

    more info.

    running 'nmap -v localhost'

    resulted in

    25/tcp open smtp


    So I updated thunderbird to reflect port 25, none for connection security, and authentication method is set to password, transmitted insecurely.

    I then try to send an email and I get the mail server has timed out..

    any advice? or what should i look at next?

    Are there any errors in your mail log (in the /var/log/ directory)?

    no, nothing in the log file. Its almost as if its not hitting the server.

    Can you use the server's IP address in Thunderbird instead of a hostname? My guess is that the hostname is pointing to another server.

    no, thats not the issue. I have even made a new server following your v12 guide and same issue. Can you share with me the settings to send email using say thunderbird?

    thanks

    thanks, followed the guide you just linked to perfectly but it still times out trying to send email. Receiving is fine, but outgoing times out. How can I verify that I should be using port 25 and that its open?

    Please post the outputs of
    Code:
    netstat -tap
    and
    Code:
    iptables -L
    
    Also check your mail log (in the /var/log/ directory) for errors.

    Same issue

    Hi

    I have the same issue.
    I followed guide and got a working system but cannot connect an email client via smtp to send mail.

    Using Squirrelmain works perfectly but trying to connect to send fails.
    If there anything I can do to help diagnose issue to assist?

    Hm, looks ok. Although the iptables output looks ok, have you tried turning off fail2ban?

    Also, does
    Code:
    telnet localhost 25
    work on the server?

    root@primary:/home/ubuntu# telnet localhost 25
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    220 myhost.server.com ESMTP Postfix (Ubuntu)

    I am going to try disabling fail2ban now as well
