Hi, since IPv6 is now officially being supported I thought I give it a try. My first step was to enter an IPv6 address into the WebGUI under Server Management - System Settings - TCP/IP I set an IPv6 address and our gateway which is a link local address (fe80::...)
I have not configured a website with an IPv6 address nor have I setup AAAA for any of the sites, yet. Eversince sendmail seems to be broken now because of me enabling IPv6. Here's what the log says: May 23 10:30:02 www4 sendmail[19489]: NOQUEUE: SYSERR(root): /etc/mail/sendmail.cf: line 292: host "2a00:fe0:0:2::600/64" unknown This is the corresponding line: O DaemonPortOptions=Familiy=inet6, port=smtp, Name=MTA-v6, Modifier=O, Addr=2a00:fe0:0:2::600/64 The sendmail process won't start any more. Just out of curiosity... why do you use sendmail and not postfix or exim? I tried to remove IPv6 configuration in WebGUI TCP/IP without success. Can someone assist, please. Mail system has been down now for two days.
