CXSNDR ERROR when sending a cox email as of January 2021
Started getting a CXSNDR error when sending an email both from Cox Mail and Apple mail apps. Started a few months ago. Seems to be intermittent where some emails will be sent but others will be rejected with this error. No help from Cox Reps.
I see from look through the forum that others have the smae problem. Has anyone found a solution?
@AZCOX, I recommend sending us an email with your full name, address, a brief description of this concern, and the header(s) to these emails to firstname.lastname@example.org so we can take a closer look for you. -Allan, Cox Support Forums Moderator
