You are going to need to figure out where that is in the dovecot (possibly a find /etc -type f -print | xargs grep -l "::1" might give you some ideas unless this is in the database where you will be needing to play with that. It may be just easier to just turn on ipv6 and get that working again as that seems to be what 'broke' mail versus the kernel upgrade. [The kernel reboot probably just brought to light a 'oh I have ipv6 required somewhere but it is deeply hidden'] -- Stephen J Smoogen.
