I am unable to send an original email right now with Thunderbird. I realize "original" is not the best descriptor but what I am trying to describe is if I compose an email to another party, Thunderbird tries to send it and immediately returns the message below even if I send the word Test in the subject line and as the one word text message:

Send Message Error Sending of the Message failed An error occurred while sending email. the mail server respnded: [VO-1] Message blocked due to spam content in the message. Please check the messge and try again.

I have tried multiple email recipients with the same results.

However, if I take an email currently in my Inbox and Forward it to another recipient, it sends it with no error.

Thanks for your help. I am sure I have done something I should not have but I cannot think of what it was.

Are you using a signature file?

Does that also happen in Troubleshoot mode (https://support.mozilla.org/en-US/kb/safe-mode-thunderbird)?

Message blocked due to spam content in the message.

The error message is from your email provider's server. So you may want to talk to them about why they block your message. Contributing factors can be

  • Bulleted list item sending in HTML format instead of plain text
  • Bulleted list item a fancy signature containing an image
  • Bulleted list item sending attachments, where certain file types may be considered suspicious by your email provider
