Can't send email after switching ISP
I have Cox for email only (they are not a provider where I moved to.) Up until recently mail worked fine but I just switched ISP's and now I can't send. I get these messages:
cxr-obgw-6001a.stratus.cloudmark.com cmsmtp 22.214.171.124 blocked. Refer to Error Codes section at www.cox.com/.../email-error-codes.html for more information. AUP#CXDNS
My new ISP seems to think the fix is on Cox because they (the ISP) are using Google for DNS.
Where do I turn to fix this?
