I discovered today that Postfix does not enable IPv6 for DragonFly. It sets a FREEBSD4 macro based on 'uname' output for the build in general, but it relies on compiler macros to enable IPv6 support and has none for DF.
I worked around that with this patch: http://web.mr-happy.com/~jfb/patches/patch-postfix_2.5.1-src-util-sys_defs.h Is simply checking for __DragonFly__ the best way to detect a v6-capable DF host? I assume there was never a v6-incapable version, since we're based on FBSD 4, but I wanted to check before attempting to submit this to the postfix project. thanks, Jeff
