Not sure if my problems are related to the email issues discussed here or not, but I'll try here first.
I registered a new domain and set up an email account for it. I can log in webmail and send via webmail, but I cannot receive at that address. All mail sent to it bounces back.
I also cannot complete the setup for Thunderbird with McAfee SpamKiller, it claims the username and password is wrong.
Anything I can try before going to official DH support?
