Cox security required to send mail - if you can't tell me what is causing this problem, then please stop sending them.

Hi Fredric.luke, it sounds like the Cox Communications Security Team detected suspicious activity your Cox.net email account or believe your email address password was compromised. In these types of situations, limitations may be placed on the amount of email that can be sent from your Cox.net email address for 24 hours. If this is indeed the case, you must immediately reset your Cox password to remove the risk to your account. (Note: If you have reset your password within the last 12 hours and still have access to your email account using your new password, you may disregard this notification.) -Becky, Cox Support Forums Moderator
