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] Jun 4 21:27:01 server100 dovecot: pop3-login: Disconnected (no auth attempts in 0

Besides of that, I've found this one here too (mail.info) Code: Jun 3 22:20:55 server100 amavis-mc[2154]: Process [2822] started: /usr/sbin/amavis-services childproc-minder Jun 3 22:20:55 server100

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?
