I changed the DNS of the website www.pcimport.com.br a 30 hours ago, to point to dreamhost. It propagated ok, but when I try to access webmail.pcimport.com.br, appears the old webmail host.
Also I can’t access by POP/SMTP. There is another settings that I need to do?
Probably it is just a timing issue. What your MX setting in DH? DH panel --> Domains --> Manage Domains --> DNS. If it is using DH email sever, it should be working by now.
