    I've installed ISPconfig on SuSe v11 using the perfect install instructions.

    I'm able to send e-mail out but the e-mail bounces when I try to e-mail a user on the ISP system.

    The bounce message says:
    From: Mail Delivery System <[email protected]>
    This is the mail system at host
    <[email protected] (expanded from [email protected])
    Is it normal to get when you "telnet localhost 25"? Isn't it supposed to reflect your hostname and domain?

    And if it is supposed to reflect your host, where do you go to change it?

    I'm guessing in my file but I'm not sure if this is the only place and I don't want to doink anything up. Any suggestions would be most grateful.

    I have similar experience (but not exactly because I am not using Suse).

    For your reference, I resolved the problem by:

    a) modifying my resolv.conf by changing it so that:

    b) add the following entries in the ISPconfig DNS manager page:
    domain (SOA):
    IP: [your server fixed IP]
    in the record page, add a hostname known as "server1" and then use the IP of your server fixed IP in the IP address field.

    In that case I found that the email bounce back problem no longer occurs.

    (Actually I've found that if one uses the true server name (e.g. instead of "" when you set up the server you will not get this email bounce back problem.)

    Hope this helps.
