Cox Blocking email as SPAM (greylisting)

According to information on the Cox website, Cox launched a network-based anti-spam solution that will allow them to recognize and block spam from known spammers using rules-based methods and also white or black lists. Although the Cox High Speed Internet subscriber agreement prohibits customers from using the service to send spam or any other unsolicited mass e-mailings, they also block users from sending individual legitimate personal and private (non-spam) emails based on an undisclosed filtering scheme.

If you have a home account with Cox you may have seen the dreaded bounced email message telling you that your email to your client has been flagged as spam. In doing so they have added the information to their filter blocking outgoing mail to friends, family and clients.

Because you have a personal account and not a buisiness account you have no recoarse.

I spoke to cox and they told me to send the email to thisisnotspam@cox.net and that will remove the email from their filter but at this time I have not seen it work.

Outgoing personal mail being sent via cox mail servers is being bounced or sent to a black hole. You may think a potential client has received this email but in reality has not. You may send another and another. You client dosen't respond because they never got the first email you promised them. You try putting in a call but no reply. They have moved on.

Do not rely on cox to send important business email to potential or current clients because they may be filtering your emails and sending them to never never land.
