Hi,

We have IPV6 disabled for security reasons on all server builds.

Why did you disable it for security reasons?

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 solution that would make dovecot resilient in all circunstances.

I wonder, if you are able to automatically deploy without ipv6, i hardly think dropping in "listen = *" to your dovecot.conf template is going to be so hard either?
