I have just been affected by this change.  However, I am able to send mail thru Cox's servers using a From address with 
my personal domains. Previously, I was sending mail thru each of my domains directly, bypassing Cox's SMTP servers 
altogether.  Now I simply changed my email client settings to Cox's SMTP server and I am able to send emails thru Cox's 
servers using the appropriate From address for each of my 3 personal domains.
