Verizon Support PLEASE read this Error or problem number 0X800CCC70. MS claims only our ISP CAN CORRECT THIS AND OUR ISP IS Verizon. Many thanks,
To resolve this behavior, contact your ISP for help. The e-mail client does not cause this behavior. From a messaging client standpoint, there are no solutions for customers whose ISPs block all SMTP Relay traffic.
Most of the new SMTP e-mail gateway software permits relaying for specific IP addresses. This is how cable modem and ADSL users can continue to use their same ISP. The cable modem or ADSL provider must provide the customer a static IP address, in turn, the customer's e-mail ISP allows relaying for that specific IP address. Banks of IP addresses can also be permitted, which may provide a work around for some corporate customers who access ISPs through their corporate LAN.
If the error message that is described in the "Symptoms" section of this article is random, it is possible that your SMTP server is checking whether the domain or the recipient name actually exists before sending the message. If the recipient's e-mail server is temporarily down or unavailable for another reason, such as high network volume, your SMTP server cannot verify the address and may reject the relay. In this case, action is not required. The message is sent when the receiving server is available again
