An error occurred while sending mail. The mail server responded: Spam detected by content scanner.
Hello Mozilla Support,
I am not able to send email. I receive the following message: An error occurred while sending mail. The mail server responded: Spam detected by content scanner.
I have been using Thunderbird for several months and haven't had a problem sending email until now. I am definitely not sending spam. I haven't made any changes to my account or server and it is not due to a firewall.
Please help.
Thank you, Victor
