I am suddenly having trouble sending emails to a particular email address. Cox is my internet provider and I have explored the problem with them. It appears to be a Thunderbird problem. When I send a message to this particular site, I get the following message: " An error occurred while sending mail. The mail server responded: <mustangmaggie@cox.net> message rejected. Refer to Error Codes section at https://www.cox.com/residential/support/email-error-codes.html for more information. AUP#CXSNDR. Please check the message and try again.

Thanks in advance for your help.

Cox is your internet provider and you are obviously sending your mail from another email domain/and email address not containing @cox.net. Cox feels that domain is not configured correctly.

We see a lot of that sort of thing here. Mostly from cheap as chips hosting providers where folks do DIY domain configurations. What is the domain name?

Hi and thank you for responding so quickly. Actually, cox.net is the domain. I don't access my emails through Cox, though, as I use Thunderbird for that purpose. Does that make sense?
