pmta3.sevrerok.in    A       176.123.8.17

    Set up rDNS (reverse DNS/PTR Record) with your server provider.

    176.123.8.12 > pmta1.sevrerok.in
176.123.8.13 > pmta2.sevrerok.in
176.123.8.17 > pmta3.sevrerok.in

    Edit PowerMTA config file

    vi /etc/pmta/config

    Find your virtual-mta configuration, replace it with

    
    smtp-source-host 176.123.8.12 pmta1.sevrerok.in
    domain-key default,*,/etc/pmta/default.sevrerok.in.pem
