I'm perfectly willing to start using ipv6 interfaces by default. I'm not too knowledgeable on the subject, but afaict an ipv6 interface will happily serve ipv4 clients if bound to a mapped address like ::ffff:192.168.1.1 so using ipv6 interfaces internally would serve both worlds. Only caveat is people running on kernels that don't support ipv6. For 2.3 we could probably start using ipv6 in favor of ipv4. Any backports to 2.2 would most likely require a compile time selection. > > I'm down to the last app not IPv6 -- dmail.

The backend connections are handled by the respective client libraries. Those are ipv6 enabled of course. Time for dbmail to move on this issue as well. > > Thanx, > > David A.
