Iam the postmaster of a own Postfix/Dovecot POP3+IMAP Installation and there is
a major problem in the Claws Win32 Version when it comes to Name Resolution of
IPv6 Addresses and even connectivity Problems if you use plain IPv6 Addresses
as Hostnames. On the Postfix Serverside i see no incomning Connection and
Claws Reports the Error: "Unknown Host". But the host is avaiable via ping -6
and tracert, i can also connect manually via telnet 25 and telnet 110 (pop)
and just send a plaintext email. Mutt and other Clients playing well with IPv6.

Note: If i provide Claws a IPv4 IP-Address, evertything works as expected.
