Hello there Loren’s phone. We have read your message. We try to help you.

The e-mail that you are trying to send to your recipient. Is not being delivered inbox or better you had a bounce back with this message that you have send us.

The server that the recipients has does not accept your incoming mail. But regonise it and returns the message that in now in your inbox.


You did send it to a non-existent email address on the remote side. If issues like this are there.

Though it can be returned also by the recipient’s firewall (or when the incoming server is down), the great majority of errors 550 simply tell that the recipient email address doesn’t exist. You should contact the recipient otherwise and get the right address.


Also settings can and could be configured wrong.

Set mailnews.wraplength to 0 (zero) in Options/General/Config. editor to wrap plain text messages to the window width and then see how they look to recipients.

Check if your messages are getting to that inbox now ?

If this is a bug and cannot be solved. Try to reinstall a fresh new version of Thunderbird . And delete all duplicated or installed software from Thunderbird before you try to reinstall the new one.

Use a good antivirus.
