I want to configure Haproxy for load balanceing of outgoing mails . for this
configuration of haproxy and postfix i have googled various artical since
last month finally i got some information from Haproxy mailling list.
To balance postfix i am using ..
HA-Proxy version 1.5-dev11 2012/06/04
postfix mail_version = 2.10-20120902
In /etc/main.cf
postscreen_upstream_proxy_protocol = haproxy
smtpd_upstream_proxy_protocol = haproxy
In /etc/haproxy.cfg
global
maxconn 4096 # Total Max Connections. This is dependent on
ulimit
nbproc 4
log 127.0.0.1 local4
defaults
mode tcp
# timeout connect 20s
# timeout client 20s
# timeout server 22s
frontend smtp_proxy 0.0.0.0:10021
mode tcp
log global
option tcplog
default_backend bk_postfix
backend bk_postfix
mode tcp
log global
option tcplog
balance roundrobin
#source 0.0.0.0 usesrc clientip
server postfix 127.0.0.1:25 send-proxy
server r23.mtp.org 74.117.56.x:25 send-proxy
server r17.mtp.org 199.71.212.x:25 send-proxy
both service haproxy and postfix running
but when i relay mails from my php application and from load balancer to
another smtp (which also have postfix 2.10) this shows error
" status=deferred (host r23.mtp.org[74.117.x.x] refused to talk to me: 421
4.3.2 No system resources)
and i am testing this all on vps server with centos 5.8
Is this configuration error or system resource related error.?
please help me thank you in advance
