WHM Proxy Rotation or Server Rotation?

It is possible to have our IP's rotate through our server from like a VPN or proxy server? The reason I ask for is because Yahoo is blocking us once we send so many. It's blocking us by IP, I would like to rotate between multiple proxies until the send completes.

Is there any way of doing this or at least keep the proxies rotating; therefore it's not coming from the same IP address all the time. I'm currently using a Linux (CentOs Distro) with WHM and Cpanel. I guess we would be hiding our true server IP address. I'm not sure if this would effect our domain keys and signature by doing this or not.

A better idea would be for us to purchase multiple IP's from our host company (all with domain keys and SPF installed). Then we could rotate between 20 different IP addresses? Can this be done for the same domain name?

Hi,

Yes you can get multiple IP and use powermta to rotate multiple IP's and get SPF/Domainkeys/DKIM signature.

Install Linux box and smtp for example postfix

Then with iptables you can rotate ips lfor,port 25 ike

# iptables -t nat -I POSTROUTING -m state --state NEW -p tcp --dport 25 -o eth0 -m statistic --mode nth --every 5 -j SNAT --to-source 10.xxx.xxx.xxx
