Hello ther steve7 u. We have read your message.

You can not install thunderbird again?

can you send a picture of this topic if it shows the error message again?

BDAT is an extended SMTP (ESMTP) command which is defined in SMTP Service Extensions for Transmission of Large and Binary MIME Messages.

The Esmtp configuration may have skipped or not installed a configuration when transferring or resetting it because a new PC or piece of software is present at the moment.

The mail servers are esmtp friendly. check your configuration for the extra options that are offered to be able to use it on the relevant server, in this case Thunderbird's server.

Just a guess, but I suggest you try again without the AVG scanning. It has caused issues in the past.

Hello there again Steve7 u.

in this case we are talking about a bounce that causes the text on your screen. If you want to use bareline entry characters to send an email, the chunking mode will automatically go into effect. With this one he is more required for his use. This concerns the email servers. email chunking indeed uses Bdat command server protocol command. Also, the server that is esmtp friendly does not support any of these requested.

There is an expected behavior. As you send us.

Greetings .

Hello there again Steve 7 u.

This operation usually defines a nonexistent email address to the receiving party. the bounce back can be caused by a firewall if it has managed to pass through a mail server. Or in response to the server not being available.

Which is usually defined as ,the mail address simply does not exist. With answer you just have to contact the receiving party for the correct email address.

This does not include actions such as chunking.

Greetings Firefox volunteer.

I'm a competent computer user (though I have no idea what bareline and chunking are), and I am not doing anything differently sending these emails than when I sent the same a week ago and Thunderbird sent them successfully (before the computer reset). The only thing that has changed is that Thunderbird was uninstalled when I had to reset my computer, and then Thunderbird was re-installed afterward. And now when I reply to my family and friends, my emails are dubbed "Undeliverable." It seems to me that the new install has something different (some setting?), but I would just like it to work like it is supposed to (and like it did before).

Another interesting thing about this issue...when I first open Thunderbird in the morning, I am able to send out emails. But it seems to be later in the day that it stops sending and gives me the above "Undeliverable" message.

Hell there again.

you are trying to send a message in the form of a pdf file.

The message also occurs or originated from mass transmission or bulk and is considered spam. please treat this topic if this continues as spam.

The receiver's server is not inclined to let it receive it. And will also have to be notified. Please contact them. about the situation with Bare line feeds in documents.

If your message suddenly can be recieved. What message do you get then?

https://support.mozilla.org/en-US/kb/security-panel-settings-in-thunderbird

This issue occurs if the expected CR-LF combination has not been added but only a single function of it has been set or otherwise. Cr but no LF. Or otherwise it has to be the other way and try to change this setting into CR-LF. Or only in LF. This could be the bug in this situation.

Editor from the email software is adding a bareline feed after every made text collum. Try to change these input fields search for configuration s with CR-LF. See if your message can be send.

Greetings Firefox volunteer.

Hello there again.

If it hasn't come out as Spam yet, you can change the values if you're only using Thunderbird. This is called the Wrapping process which is used as this method. And can be solved by setting its value to 0.

so that no more empty fields are placed behind a written text field automatically. So this function can be treated. And will have to be set to zero. So that messages can be forwarded again.
