Does Rackspace really a spam supporter?
I am with Rackspace, they use MailMax as mail service.When we are sending our news updates to our customers (approx. 800+ ppl/emails), some of them (like 10 to 20) got returned. And when I check the reason, it said the IP is in the black list from http://spews.org...etc
Anyone know how to fix this type of problem?
