    Hello,

    I am currently facing an issue with Qmail. My email server has been listed by CBL due to the fact that sent emails show an invalid HELO greetings. According to the helocheck@abuseat.org rejection the HELO for my IP address has a valid syntax. Nevertheless, when I check the full header of an email sent from my address I find my computer IP address instead of the server's one.

    How do I fix this?

    I found many relevant threads in this and other forums, but no one worked for me.

    The file /var/control/me has my mail server's fully qualified domain name.
    I have also created a badhelo file in this directory with the value
    Code:
    # Reject spambots using our mailserver's 11.22.33.44 IP as HELO/EHLO
    ^11\.22\.33\.44$
    # Reject spambots using our mailserver's a.mx.my.serverdomain.tdl name as HELO/EHLO
    ^a\.mx\.my.serverdomain\.tdl$
    Where am I mistaking? I am having many troubles because of this issue, and the difficulty to get it solved.

    Any feedback is truly appreciated. I use Plesk 12 on Ubuntu 14.04.2 LTS.

    Thanks!
    a.

    What do I have to adjust my Plesk - Postfix Mailserver
    A HELO - mydomain.de sends, and not just an EHLO

    220 webmail.webmail.matthias-web-buero.de ESMTP postfix (Debian / GNU) [2235 ms]
    EHLO PWS3.mxtoolbox.com
    250-webmail .matthias-web-buero.de

    Hi Kamikaze,

    you seem to misunderstand something here. Pls. use:

    Code:
    telnet webmail.webmail.matthias-web-buero.de 25
    you will RECEIVE:
    Code:
    Trying 87.106.59.72...
    Connected to webmail.webmail.matthias-web-buero.de.
    Escape character is '^]'.
    220 webmail.webmail.matthias-web-buero.de ESMTP Postfix (Debian/GNU)
    YOU GREET with:
    Code:
    EHLO webmail.webmail.matthias-web-buero.de
    and the ANSWER is an output of possible options at this mail - server:
    Code:

    250-AUTH PLAIN LOGIN CRAM-MD5 DIGEST-MD5
    250-ENHANCEDSTATUSCODES

    Code:
    220 webmail.webmail.matthias-web-buero.de ESMTP Postfix (Debian/GNU)
    
    Test    Result
