Hello, am working on setting up HAProxy and would like it to LB connections to our Zimbra server. So far I have the following:
frontend zimbra-mta-frontend bind 172.30.8.22:25 mode tcp no option http-server-close timeout client 1m log global option tcplog default_backend zimbra-mta-backend backend zimbra-mta-backend mode tcp no option http-server-close log global option tcplog option smtpchk HELO mydomain.com timeout server 1m timeout connect 5s server zmta1 zm1.mydomain.com:1025 send-proxy This works fine and proxies the connections through to Postscreen on the Zimbra very nicely indeed. The problem I am having is how does one check that the service is running okay ? When I view in the statistics page the zmta1 line is greyed out. I see that there is also a check-send-proxy option but not entirely sure of how it works. Any help appreciated please.
