I have used proxy protocol for SMTP as this tutorial:

It worked successfully.
I wanted to do smtpchk so that I added to the config:
server postfix01 X.X.X.X:10000 send-proxy check
Then the log told that the server was down though it is not:
May 27 14:07:51 localhost haproxy[6890]: Proxy ft_postfix started.
May 27 14:07:51 localhost haproxy[6890]: Server ft_postfix/postfix01
is DOWN, reason: Initializing, check duration: 0ms. 0 active and 0
backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue.
May 27 14:07:51 localhost haproxy[6890]: proxy ft_postfix has no
server available!
I also tried
server postfix01 X.X.X.X:10000 check send-proxy
but the result is the same.
I could do smtpchk normally without proxy protocol:
May 27 14:30:02 localhost haproxy[24755]: Server ft_postfix/postfix01
is UP, reason: Layer7 check passed, code: 220, info:
"mail.mydomain.com ESMTP Postfix (Ubuntu)", check duration: 2ms. 1
active and 0 backup servers online. 0 sessions requeued, 0 total in queue.
I am using
http://haproxy.1wt.eu/download/1.5/src/devel/haproxy-1.5-dev18.tar.gz
on Ubuntu 12.04.
