    There seems to be something wrong with name resolution on your system.

    What's in /etc/resolv.conf and /etc/hosts? What's the output of
    Code:
    ifconfig
    ?

    There's something wrong with name resolution on your system. Please modify /etc/resolv.conf so that it looks like this:
    Code:
    nameserver 145.253.2.75
    nameserver 193.174.32.18
    nameserver 194.25.0.60

    That worked

    Why wont the name servers I had in there work? Thanks for the help.:)

    One more thing I have a configuration error with my certificates when I open thunderbird I get an error sating

    You have attempted to establish a connection with mail.mydoamin.org However the security certificate presented belongs localhost. I get a similar message when sending email. Do you know ho I can fix this I tried doing what some of the other threads sugested bu it hasn't worked for me.

    Thanks Falko you're awesome:D

    falko Super Moderator ISPConfig Developer

    Maybe they aren't nameservers.

    Please create a certificate for mail.mydoamin.org instead of localhost as shown in the tutorial.

    Similar Problem

    FORUM MOD: This might be better as a new thread, but I posted here...

    I had a similar problem with ISPConfig and wanted to let the world know what happened and how I fixed it.

    I installed ISPConfig on a new FC6 server. I set up my first account, and then set up an email user for that account. then I sent an email to that user from another domain. The email arrived, and so did a zillion bounce messages. Here is what was in the maillog file (hand typed...)

    ...<snip>...to=<[email protected]>, relay=none, <snip>, status=bounced (mail for localhost.localdomain.mydomain.com loops back to myself)

    I am not an expert at this but if the email was delivered to the mailbox, why was there also a bounce to begin with? I fixed the bounce by doing this:

    I added this line to the bottom of /etc/postfix/local-host-names

    localhost.localdomain.mydomain.com

    then restarted postfix. Seems to work now.

    Can someone give me a hint as to why the bounce was generated to begin with?
    Can someone tell me if I really fixed this or just put a "bandaid" on a misconfiguration?

    Thanks

    The answer for this error is always the same ;)

    If you have a error message containing the words "loops back to myself", take the domain that is mentioned in the error message and append it to the file /etc/postfix/local-host-names and restart postfix.

    So, to make it short, your fix was correct :)

    I also got this error, after updating ISPConfig.
    The solution worked for me also.

    But why does this happend?
    Will it happend the next time I upgrade ISPConfig?

    I have many domains hosted on my server, but I just had to put on of them in the /etc/postfix/local-host-names file to make it work, why?
    Also, the mail users on all domains recived the messages, not just the ones on the "problem domain", why?

    Many questions, I`m just trying to understand what actually happend. :)
