# With >=python-3.3, the built-in ipaddress module handles the parsing
# of IP addresses. If python is built without ipv6 support, then
# ipaddress can't parse ipv6 addresses, and the daemon will crash if it
# sees an ipv6 SPF record. In other words, it's completely broken.
#
# Ideally this would remain optional for python-2.x, but until there's
# an easy way to do that, "maybe annoying" seems a better option than
# "maybe broken."

# The lower version bound is reported at,

# The lower bound on pyspf is not strictly necessary, but some features
