I'm getting emails blocked that I'm sending out to Yahoo & Hotmail email accounts:
YAHOO: All messages from xxx.xx.xxx.xxx will be permanently deferred; Retrying will NOT succeed. See http://postmaster.yahoo.com/421-ts03.html
HOTMAIL: Unfortunately, messages from xxx.xx.xxx.xxx weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors.
How do I get HELP from Dynadot with this problem? I see no number to call.
