At one point I was building Courier regularly from source and the build
configuration offered the choice of whether or not to build for a v6
stack.  For some reason a v6 build caused a problem, which I don't
remember now, but "::ffff" was dropped from IPs when I make a straight
v4 build.  This was problematic with some of the maildrop scripting I'd
done, so I switched back.

These days I'm using the Courier package distributed with Ubuntu Server,
which is built with IPv6 capabilities, although it doesn't handle any
inbound email with v6 addresses other than v4-mapped v6 addresses, as
noted in your post.
