I have Unlimited Business, Unlimited Storage Workspace email account with GoDaddy and I usually access it via Microsoft Outllook and POP3.
Today i sent an email and got a refusal message from the server - "550 User xxxx has exceeded 24 hour sending limit. Message to 250 recipients out of 250 allowed have been sent. Relay quota will be reset in ......"
Now, I checked - there is no way I sent 250 email in the last 24 hours. And in any case, I have an Unlimited account.
When I use the same email account via Webmail - no problems. emails are sent just fine.
