    Hi,
    first, I'd like to thank you for all the tutorials you offer here and howtoforge.com! Really great work! Thank you very much!

    I am running an ISPConfig install within a Proxmox 4.1 CT w/ disabled firewall. Installation went smooth, followed this tutorial/howto:
    The Perfect Server - Debian 8.4 Jessie (Apache2, BIND, Dovecot, ISPConfig 3.1
    All is working fine, except the mailsystem.
    At first, I ran into an "fatal: no sasl authentication mechanism"-error, which I'd fixed with
    Code:
    chmod 666 /var/spool/postfix/private/auth
    and
    Code:
    chown postfix:postfix /var/spool/postfix/private/auth
    followed an another howto here at howtoforge.com.

    Anyway, the mailsystem is not available. I can't send/receive any e-mails. Even through webmail.
    mail.log
    Code:
    Jun  4 21:27:01 server100 postfix/smtpd[32317]: disconnect from localhost[::1]

    Besides of that, I've found this one here too (mail.info)
    Code:

    SOLVED: Had to change the parm inet_interfaces in /etc/postfix/main.cf to

    Code:
    inet_interfaces = all
    #inet_interfaces = loopback-only
    ;)

    Hello webhunter, I have a question for you:
    Do you have Proxmox and Ispconfig installed on the server? Or Proxmox on server and ISPConfig into VM?

    So, Proxmox as host and ISPConfig as a guest.
