    Hi guys,

    I am having some email issues with my installation of ispconfig 2.2.25. If I send an email to any of my users on any of my domains, the email obviously reaches the server but I then get an error message returned from my server.
    I know this has to be a simple config error, almost certainly on my part, but I really want to get this sorted out please.

    This is what I get from the server.

    HTML:
    This is the mail system at host cpc2-norw3-0-0-cust15.
    
    I'm sorry to have to inform you that your message could not
    be delivered to one or more recipients. It's attached below.
    
    For further assistance, please send mail to postmaster.
    
    If you do so, please include this problem report. You can
    delete your own text from the attached returned message.
    
                       The mail system

    Do you use cpc2-norw3-0-0-cust15.localdomain in /etc/postfix/main.cf? What are the outputs of
    Code:
    hostname
    and
    Code:
    hostname -f
    ? What's in /etc/hosts?

    Thanks for the response.

    The strange hostname is due to Virgin. In order to use a static IP they insist on setting the hostname via dhcp.

    Both hostname and hostname -f give
    HTML:
    cpc2-norw3-0-0-cust15.pete.cable.ntl.com
    /etc/postfix/main.cf has
    HTML:
    myhostname = cpc2-norw3-0-0-cust15
    This is /etc/hosts
    HTML:
    # Do not remove the following line, or various programs
    # that require network functionality will fail.
    127.0.0.1               localhost.localdomain localhost

    Please run
    Code:
    postconf -e 'myhostname = cpc2-norw3-0-0-cust15.pete.cable.ntl.com'
    /etc/init.d/postfix restart

    Thanks Falko, worked a treat. I knew it would be something silly I'd missed.
