I have been having a similar issue ever since they brought Cloudmark in to the picture. The issue I have with all of their answers is simple. I am AUTHENTICATING with a valid email account. I am not using port 25. I am not sending from a server. I am sending from a typical email client, in this instance, Thunderbird. Cox needs to fix this oversight. I do not use webmail, nor do I use IMAP. The purpose of using port 587 is for authenticating the user, not the connection. It should not matter where I am sending the message from as long as my login is valid.
An error occurred while sending mail: The mail server sent an incorrect greeting: cxr-obgw-5004a.stratus.cloudmark.com cmsmtp xxx.xxx.xxx.xxx blocked. Refer to Error Codes section at www.cox.com/.../email-error-codes.html for more information. AUP#CXDNS.
Thunderbird gives the correct greeting for an email client.
That type of response usually indicates that the IP address that you are sending from does not support reverse DNS. This is now required since we have updated our security settings/measures. You can check to see if the IP you are sending from is supports reverse DNS here mxtoolbox.com/SuperTool.aspx (change the dropdown to reverse lookup and enter the IP address). If you need to locate your IP address, you can go to www.whatismyip.com while at the location that you are having trouble sending from.
