After my domains were transferred to Dynadot, I got a message saying that my name servers stayed the same so I my e-mail services should not have been effected. Yet, I haven't been able to pick up my e-mail via Gmail using POP3 as I had before the transfer.
When I check my IP, I receive this error message:
Name Server Misconfigured - One or more name servers for this domain is not returning an IP address. Please contact the admin for the name server.
At the time, you were using your former Registrar's Name Servers in order to point your traffic to Google's servers.
If that is the case, you will have to set up your DNS records again after the transfer completes, since your former Registrar probably won't provide hosting for you any more.
