Hello,
I hope this is the right place to start. Ubuntu server the default listener
configuration in dovecot.conf uses both IP4 and IP6 on systems that have IP6
disabled dovecot will not start.
Is it possible to set the default to:
listen = * to only bind to IP4 for installation and initial
I have tried replying twice.
We have IPV6 disabled for security reasons on all server builds. An installer
script failed which is how we caught this issue. We can see it is due to the
config line.
A graceful fallback to IPV4 if the IPV6 stack is not available would seem to be
an elegant solu
I think we are off topic.
We have a network policy that until such time as we have fully implemented the
same security we have on our IPV4 network we simply do not allow IPV6 as it is
another attack vector we are not fully upto speed on. So we block all IPV6 at
the perimeter and on all switche
IPV6 is disabled in the grub command line. So before the OS boots. So there is
no IPV6 support in the system. Unless one enables it in the Grub bootloader.
Cheers

That config is not the standard as from the repos. As the standard one has that
line commented out signifying it is the default and the default is now:
listen = *, ::
The :: is the issue here as if there is no IPV6 stack and dovecot crashes as,
as a default it expects IPV6 to be there
