If someone has time to contribute code, I will consider it. Note
that there are two Postfix haproxy handlers: a blocking handler
for smtpd, and a non-blocking handler for postscreen.
The Postfix haproxy handlers will accept both IPv4 and IPv6. I have
no idea what send-proxy-v2 looks like, but if they did not complicate
things by switching to some non-text format, then it should be easy
to reuse most of that code for send-proxy-v2.
