Hi, I’ve just switched a site over to my Dreamhost account by updating the domain nameservers to Dreamhost’s nameservers. The website is resolving correctly, but when I try to access webmail.mydomain.com, I get a blank page (after the SSL security warning). Checking the whois records for the domain show that everything is resolving as it should be (as far I can see), and matches other domains I’m hosting where I don’t have this blank page issue. I made the change yesterday, is it possible that it’s a DNS propagation issue, or is it something else likely to be at fault? Thanks for any help.
