Postfix: Multiple Relays

Contoh DNS SMTP Server

mxr IN A 192.168.1.121
mxr IN A 192.168.1.131
mxr IN A 192.168.1.141
mxr IN A 192.168.1.151
mxr IN A 192.168.1.161

AKan di resolve secara round robin.

Edit

/etc/postfix/main.cf

Isi

relayhost = mxr

and Postfix relays with every of these ips in roundrobin style :)
