Problems using HAproxy with postfix

Problems using HAproxy with postfix

Problems using HAproxy with postfix

(OP)
Hello All,

So I have been using HAproxy for a while for web traffic and I thought I would try and use it for incoming email for my domains, my config is as follows



and I have added this to my postfix main.cf


I can see the source IP in Postfix logs, so it must be parsing the proxy header correctly, and yet immediately after the 220 from postfix, the proxy kills the connection .. see wireshark trace


I am running HAproxy 1.7.11 on pfSense 2.4.4 and Postfix is 2.10.1 on Centos 7.
I suspected the cause here might have been the old version of postfix with Centos not compatible with latest proxy protocol being used by HAproxy, but I have also tried replacing the backend with postfix 3.1.4 on Fedora 24 .. and I get exactly the same problem.

Any ideas what I have missed? It is probably something really obvious !!

Steve

Problem sorted with help from PfSense forum, the problem was the timeouts on the backend .. they are in ms !

Thanks
