first, my old newsletter system didn't take IP address in consideration but all email are verified and voluntary recipients.
That said, as Dreamhost newsletter system do not accept import of mailing list if a valid IP address is not provided with each email, I will not use it and I want to install Acajoom on my Joomla site, instead, hosted on Dreamhost.
The question is : as it is a third party software, will Dreamhost let it do mass mailing without having these IP ? I didn't find the answer anywhere.
Thank's for effort to answer.
