I need your help please. Right I'm going to order another dedicated server but i am a Linux noob (it has to be Linux and not Windows). Now i currently have a number of linux dedicated servers for mailing but because cPanel/WHM doesnt support DKIM they are getting blocked by Yahoo. Now can someone provide me with the perfect software configuration which support SPF, DomainKey and DKIM. I will also need some sort of web based script which i can login to and view the mailing queue etc..
The mailing software must be able to handle large amounts of mailing of say 30,000 mails an hour.
if you think that DKIM will white list you or let you send 30k email per hour then its a dream, This is no longer possible , Yahoo, Hotmail won't let you do this anymore.....
I can currently send over 15,000 emails a day to yahoo, hotmail etc.. Its just i need DKIM to add more security to the emails so the ESP can allow me to send more emails a day. For example Yahoo wont allow me to join their bulk mailing list until i have DKIM.
