With just 2 email addresses that I have been using for years, I suddenly get this Undeliverable message when attempting to send emails using Thunderbird:

"The mail client submitted this message with bare line feeds, which cannot be sent via SMTP protocol DATA command and receiving system does not support BDAT"

I can receive emails from the 2 addresses fine, I just can't send to them through Thunderbird. When I sign in to Hotmail Outlook Live I can send and receive to these addresses with no problem.

I'm stumped! Any ideas? Can I reset Thunderbird?

Thanks

I have been using Thunderbird as my default email for years and have run into my share of issues. Out of nowhere, starting this morning, I am unable to send emails from Thunderbird at all. I spent about 2 hours on the phone with my service provider trying to figure it out. The unfortunate conclusion I have come to, is that unless you can fix this issue for me, I will be using Outlook going forward. Let me be clear, I HATE OUTLOOK! but I am running out of options other than to throw away the email address I have been using since about 1990.

This is the message I get when the email does not send. This particular one was to trs.ky.gov, but it doesn't matter who the recipient is, the only ones that don't get this message are those I send to myself.

Your message contains invalid characters (bare line feed characters) which the email servers at trs.ky.gov don't support. reb Office 365 julie.soard Action Required Recipient

Bare line feeds unsupported

How to Fix It It appears that your email program added invalid characters (bare line feed characters) into your message when you sent it. Try using a different email program to send your message. If the problem continues send this non-delivery report (NDR) message to your email admin for assistance.

More Info for Email Admins Status code: 550 5.6.11

This error occurs when the email program or device used to create or send an email message adds bare line feed characters into the message. When bare line feed characters are included in a message, the SMTP protocol chunking feature is required to transmit the message between email servers. Chunking uses the SMTP protocol BDAT command, but the recipient's email server doesn't support the BDAT command.

To fix the issue, the sender should send the message using an email program or device that doesn't add bare line feed characters to messages. Most modern email programs don't add bare line feed characters.

If the sender is using a device like a fax machine, printer, or scanner, it's likely an older model that doesn't support the SMTP protocol BDAT command. To fix this error, you'll need to replace the device with a newer model that supports the BDAT command. The industry standard recommendation to support SMTP chunking was published in 1998 so most devices manufactured during the last decade support this feature.

Another option is for the email admin at the recipient's domain to upgrade their email servers to servers that support the SMTP protocol BDAT command. Most modern email servers support BDAT; however, some free and older email servers don't support it.

I had already post this problem recently, but in spite of Thunderbird already had two interim point releases 102.1.1 and today's 101.1.2, this problem remains.

This situation did not occur in older versions, and I cannot use pop3 access to AOL email account with "normal password" (encrypted). For the time being, I am accessing AOL web mail using Firefox.

I tried unsuccessfully all other authentication methods, so no authentication method is working with AOL.

This is the Thunderrbird error I get when using OAuth2 authentication method:

"The server does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings".

It is not true, AOL does support the OAuth2 authentication method.

I use GoDaddy.com as my ISP provider and they have ported all the accounts over to MS Outlook. It worked fine last week, and suddenly I'm getting this "Illegal characters" message. Any hints?

A couple of days ago I started getting error message stopping me from sending my emails. The message is as follows:

Sending of the message failed. An error occurred while sending mail. The mail server responded: stray newline detected. see http://cr.yp.to/docs/smtplf.html. Please check the message and try again.

I have not been able to fix the issue.

I can receive emails OK, but can't send as the above error reading stops the send

Hope you can assist in solving the problem. Note: fixing computer issues is somewhat of a challenge.

Firefox just locks up. The mouse cursor can be used to resize the window, but is otherwise unresponsive, except to to minimize, maximize or close the window. If I click minimize and then restore the window, Firefox will have executed the last mouse-click before minimizing. This happens after five minutes or so after starting Firefox, whether I have only 4 or 5 tabs open, or a whole pile of tabs. All I can do is click X in top RHS, and then restart Firefox. Then click the "recently closed tabs" to get back to where I was. I have tried clearing the cache and (most of) the cookies. As well I did a complete refresh of Firefox, and disabled all the add-ons, but the problem is still there Running on a (old) Lenovo Thinkpad E545 with 16GB, Ubuntu in a SSD using a 50 GB partn with 30GB free. This problem occurs only in Firefox- all other apps continue to run!

I have, very reluctantly, had to stop using Windows Live Mail, because gmail will no longer support it. It was a great email program and it did everything I needed. Thunderbird would seem to be the nearest thing I can find to replace Live Mail - but there seems to be some quite staggering basic functions that are missing from it. Maybe I'm alone in wanting to include a picture or two in my emails..? - not as attachments, but as part of 'the visual letter', within the text? Live Mail must be 20 years old at least - but in Live Mail I could insert an image; drag the corners to resize it; add a box rule if I wanted to; and send it on it's way. In 21stC Thunderbird I can, with many a dialogue box, insert an image... but even when I've worked out how to 'resize it', it doesn't actually reduce the file size of the image sent..! So a 7MB image, when 'resized' to something less than 1MB... still actually gets transmitted as a 7MB image - and takes forever! So my question is. How come an ancient, now almost defunct program like Live Mail, is twenty times more agile and user-friendly than 'up-to-date' Thunderbird? And before anyone mentions 'add-ons' - Live Mail did all of this straight out of the box! No 'add-on' searching or anything else required. But maybe including a picture or two in an email is a fairly revolutionary concept? With thanks for your thoughts.

I've been using Thunderbird for a long long time and have always had many imap accounts setup, including a Yahoo Mail account.

As of just the other day (I believe Tues, June 7, 2022), suddenly and unexpectedly, Thunderbird 91.10.0 (64-bit) began showing ALL of my mail folders in the Yahoo account on the server, when I have always had many folders hidden (in unsubscribed state).

I have Thunderbird installed on 4 computers, and, as I launched TB on each of them, the displayed Yahoo folders updated to all folders on each computer (I had originally set up my profile on one computer and then later copied it to each of the others).

When I go into the TB yahoo account settings to re-unsubscribe and apply the settings and then restart TB, all folders remain showing... I cannot seem to get TB to once again unsubscribe to the folders I'm not interested in seeing in TB.

For reference, other imap accounts I have configured in the same profile remain with the same subscribed/unsubscribed settings I've always had.

If anyone has any ideas or explanations or a recommended fix, I'm all ears! ty!

As of 16 August Firefox Development Edition continually crashes.

Firefox standard is fine.

Tried the following 1. Shutdown and restart 2. Refresh 3. Uninstall, download and reinstall (4 times) 4. Chkdsk /r with restart then uninstall and reinstall 5. Open in troubleshoot mode 6. Tried incognito window 7. Tried disabling AV (Eset)

No change other than when the crash happens. Initially it would require opening a few tabs and browsing - now it crashes on startup.

Given that no other applications are behaving adversely, that Firefox standard works, that this was working find until 12 hours ago - my suspicion is it is something to do with the Developer edition.

Any other suggestions welcome.

I´ve found out, that this Workaround seems to no longer to work since Ver. 101.0.1 (last working Ver.)

This is especially regarding Downloads triggered out of the embedded PDF Viewer in Firefox, when You click on the "Download PDF" Symbol.

Until this Ver. You could still bring back the "Choose What you want to do with the file" Window if You set the mentioned about:config setting to false (linked thread above).

I see this actually as quite crucial and almost a bug, since You will have departments with Workflows build around this. - Thank You for any insight or help
