    cd /root/PMTA/
unzip PowerMTA5.0r1.zip
cd /root/PMTA/PowerMTA5.0r1
yum install PowerMTA-5.0r1-201909161531.x86_64.rpm
service pmta stop
service pmtahttp stop
rm -f /usr/sbin/pmtad
rm -f /usr/sbin/pmtahttpd
cd  /root/PMTA/PowerMTA5.0r1/usr/sbin
cp * /usr/sbin
chmod -R 755 /usr/sbin/pmta
chmod -R 755 /usr/sbin/pmtad
chmod -R 755 /usr/sbin/pmtahttpd
cp /root/PMTA/PowerMTA5.0r1/license /etc/pmta

    Restart PowerMTA

    service pmta start
service pmtahttp start

  • PowerMTA IP Rotation

    To setup IP rotation in PowerMTA, configure multiple IP on the server. Setup rDNS for each of these IP, point a sub domain to these IPs same as the reverse DNS entry.

    pmta1.sevrerok.in    A       176.123.8.12
pmta2.sevrerok.in    A       176.123.8.13 
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
    
    max-msg-rate 400/h
    



    smtp-source-host 176.123.8.13 pmta2.sevrerok.in
    domain-key default,*,/etc/pmta/default.sevrerok.in.pem
    
    max-msg-rate 400/h
    



    smtp-source-host 176.123.8.17 pmta3.sevrerok.in
    domain-key default,*,/etc/pmta/default.sevrerok.in.pem
    
    max-msg-rate 400/h
