Whenever I try to access my e-mail Iget a cannot find servor or DNS error?

Try to access it just using the IP address (you can get this if you look at 'details' of old emails you sent). If you CAN, then there is a DNS error. If you have already waited a few days (or three months) and it still doesn't work, you should make sure the DNS entry was made with whoever your DNS provider is. If you CANNOT reach it with the IP address, it is more likely your email server has a problem.
