Unable to send out an email using Mozilla Thunderbird
Attempted to forward a fraudulent email back to JP Morgan Chase bank (firstname.lastname@example.org) and received the following error message (rekeyed in as your system will not accept a paste-up):
"An error occurred while sending mail. The mail server responded: <email@example.com> 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."
Have not experienced this problem with other email messages.
Thank for looking into it.
