Comment (by teor):

 As far as I'm aware, the current tor code treats accept and accept6
 identically, and treats reject and reject6 identically.

 When an accept or accept6 line has an address "*", it's treated as "all
 IPv4 and IPv6 addresses". For example, "accept *:443" and "accept6 *:443"
 both mean "accept connections to all IPv4 and IPv6 addresses on port 443".

 So all ExitPolicy lines in the attached torrc past line 39 are being
 ignored:
 "ExitPolicy reject6 *:*"

 However, if you specify "accept6 *6:443" you will get the behaviour you're
 looking for: "accept connections to all IPv6 addresses on port 443".
