    I am running mandriva 2006 perfect setup. I have added squirelmail as a webmail client by installing the rpm.. I don't know if this is what seemed to break postfix, but I can no longer receive any mail. By this I mean that the mail client (thunderbird, ispconfig webmail, squirrelmail, etc.) always says that there is no mail on the server. This goes for any domain I have setup. I was recieving mail yesterday. All of the correct domains are in the postfix local hosts file and the main.cf is looking there. I can send mail with no problem from any client. Any ideas on where to look?

    Please check your mail logs for errors.

    Also check with the command:

    dig MX yourdomain.com

    If the MX records of your domains still point to your server correctly.

    The MX records are fine. I do not know where to lok for the error logs.

    The logs are in the directory: /var/log/

    The mail logs are normaly named "mail" or "mail.log"

    I am getting this in the mail info file:
    Feb 26 13:38:21 cjt-design-server postfix/smtp[4526]: BF9B61AEB0D: to=<chris@cjt-design.com>, relay=cjt-design.com[216.144.242.27], delay=1, status=bounced (mail for cjt-design.com loops back to myself)

    mail is being received for cjt-design-server.com but not cjt-design.com.

    Please add:

    cjt-design.com

    at the end of the file:

    /etc/postfix/local-host-names

    and then restart postfix:

    /etc/init.d/postfix restart.

    Put cjt-design.com at the end of /etc/postfix/local-host-names (where it says that you can make manual entries) and restart Postfix.

    tag on to this thread:

    1) my main ispconfig domain is example.com
    i'd like to know what i should set inside /etc/postfix/main.cf for these 2 variables:
    myhostname = mail.example.com (?)
    mydomain = example.com (?)

    2) i have another domain sub1.example2.com that is managed by my ispconfig

    3) i tried to send a mail to web7_user1@sub1.example2.com and got the following error:

    <web7_user1@mail.example.com> (expanded from
    <web7_user1@sub1.example2.com>): mail for
    mail.example.com loops back to myself

    4) may i know why i got this error, and how to resolve it?

    5) do i need to define a MX record for example2.com?

    thanks

    What's the output of
    Code:
    hostname
    and
    Code:
    hostname -f
    ? What's the output of
    Code:
    dig -x <your_public_IP_address>
    ?

    Put mail.example.com at the end of /etc/postfix/local-host-names and restart Postfix.

    It's not a must, but it's better. If you don't have an MX record, then mails go to the IP address that example2.com points to.

    it is totally something else which i defined during installation of FC4
    must the hostname be part of the fqdn?

    gives me:
    hostname: Unknown host

    Code:
    ;; QUESTION SECTION:
    ;aaa.bbb.ccc.ddd.in-addr.arpa.     IN      PTR
    
    ;; AUTHORITY SECTION:
    bbb.ccc.ddd.in-addr.arpa. 900     IN      SOA     <DNS2.myisp>. <DNS2.myisp>. 1133150170 21600 1800 1209600 86400
    
    
    ok, now i can receive email, but i cannot send out...
    probably because my hostname and fqdn are not set properly...

    Can you post the real output instead of placeholders?

    ==========================
    $ hostname
    quatiseasia

    $ hostname -f
    hostname: Unknown host

    $ dig -x 203.81.39.42
    ;; QUESTION SECTION:
    ;42.39.81.203.in-addr.arpa. IN PTR

    ;; AUTHORITY SECTION:
    39.81.203.in-addr.arpa. 10800 IN SOA dns1.pacific.net.sg. hostmaster.pacific.net.sg. 1133150170 21600 1800 1209600 86400

    ==========================

    what is the significance of unix hostname in relation to
    DNS records, mail domain setting etc?

    appreciate your help

    Hm... this doesn't help me. I was hoping for a FQDN that you could use in /etc/postfix/main.cf. Do you have an FQDN in /etc/hosts?

    If not, you can use

    Code:
    myhostname = mail.example.com 
    mydomain = example.com
    in /etc/postfix/main.cf, but it's always better to have a technical domain that you don't use for hosting web sites and email addresses...
