When I try to send my emails I keep getting this error message Service unavailable; Client host [208.115.247.217] blocked using clients.rbl.e-scout.net; host 208.115.247.217 blocked due to abusive behavior from your network. Please contact servers@ispn.net for resolution..

My isp is virgin media and I use Mozilla for browsing and emails. I have been with them for many years but recently I found that although I am receiving emails I can't send them . I get this message.

Sending of the message failed. An error occurred while sending mail. The mail server responded: Authentication Required (VM401). Please verify that your email address is correct in your account settings and try again.

I installed the latest Thunderbird program and installed successfully on Windows 10 PC. The Inbox emails imported okay but the sent emails, draft and all other folders are not importing from Gmail. Help please !

I am with Telstra ( Australia ) Bigpond internet with saved passwords which following recent ( Thunderbird) update Thunderbird cannot connect to the server. I have not changed any settings or passwords prior to this error see attached for error I am also a donor to Thunderbird.

A week ago my whole computer went kaput. I pay for cloud back-up so everything except Thunderbird was fully restored. I know noting about computers. My friend, an IT pro who built and sold me this machine, has worked hard without success. This is my home desktop machine running Windows 10. I can access incoming mail through AT&T Yahoo Mail. And today some kind AT&T person spent two hours with me on the phone. Now I have a newly assigned security code and, to my surprise, a functioning Thunderbird. However, my hundreds of addresses have not reappeared nor have the thousands of saved emails in my various local folders. I believe what I have now is a newer version of Thunderbird. Much of it looks different. And weirdly there was a button for "old email" that I hit and started to receive things sent to me as far back as 2007. I think it stopped at some capacity limit. I am sure most of what came through I don't want but I certainly don't want to permanently delete things I may have moved to another folder. The AT&T person got me to some repair page with step-by-step instructions for hooking up with Thunderbird but he got stymied at some point. I am at a loss here and would appreciate help. Thank you for your time and attention.

Thunderbird used to have a panel on the left-hand side of the screen which listed folders such as bin, sent, etc etc. This has disappeared and I do not know how to access folders such as bin, sent, trash, important etc.

Hello, we are running Thunderbird 128.1.0osr (32-bit) released on 8/6/24. Ever since the upgrade my husband's email has not worked correctly.

Around that same time, he received a pop up within the Thunderbird app asking for donations from Thunderbird. The popup would not go away and my husband lost a ton of his email.

Ever since these two events his Thunderbird email won't work correctly.

Messages since 8/4/24 at 6:32 am DO work correctly. Emails prior to 5/6/23 also work correctly. Any message in the time period from 5/6/23 at 11:26 am to 8/4/24 does NOT work correctly.

We are having the same trouble with the sent items folder.

We use a third party email that we import into Thunderbird and have used the third party email and Thunderbird since at least 2020 and never had this problem.

We can see all the message headers in our email list, but when we click on the email, nothing shows up. It will briefly say "message loading" at the bottom corner, but the email is totally blank. Furthermore, the message that peeks out at the bottom is the last email that we clicked on from the section of emails that does work. It is not changing to the email we are actually clicking on.

For example: lets say we have an email with message header "thank you for your order" received on 8/15. We click into that and it pulls up fine.

Then we go into older email from 7/31. The message header is "hurry sale ends today". If we click on that, it will say "message loading" at the bottom corner. However, the message preview at the bottom of the screen still displays the from/to/subject from the previous email we viewed from 8/15 "thank you for your order" (the message from 8/15 shows as blank though).

Even if we double click the message from 7/31 that we are trying to view, it just pulls up a blank screen. The bar at the top will briefly display the correct message title that we are trying to open, then it just blanks out.

Steps we have taken:

1. In Account Settings/Privacy I clicked to "allow remote content". This made an improvement as prior to this we were having the same problem even with recent messages. We could see one or two messages that had just arrived, then the third message we couldn't see. We have messages set to delete on the server after so many days. So I think it was able to recover the message that were still on the remove 3rd party server.

2. We moved a lot of the emails into archive folders as I thought the inbox may be too large. That didn't make any improvement.

Thanks for any help you can provide. My husband has a lot of really important information in his emails that he needs.

I’m hoping that there is someone out there that could help me with my e-mail problems.

I have been a Thunderbird user for what seems like 30 years or more, but certainly it is a long time. For the best part of this time, so at least for over 15 years, I have been having problems that no one has been able to help me with. But, I just love how Thunderbird is laid out, and honestly, I am a creature of habit! Many friends have advised I move somewhere else, but have refrained to do so.

Where to start! My initial provider was madasafish, and later ported over to Thunderbird. After a few years, a female techie. friend set up my mails to use on PlusNet, so I could receive and send on my mobile too.

This went fairly well for a while, until PlusNet were not providing a very good service for e-mails, so now it is nearly impossible to use PlusNet, as after each action such as transferring an e-mail to a folder, it goes into refresh mode, and can sit there for minutes or hours! Is it possible to sync. my e-mails with a better provider other than PlusNet, and if so, could you please help me out with this?

However, a problem that I’ve had for some time now is not only have I lost a lot of e-mails from Thunderbird (and no one has been able to help me to recover them), but I am having difficulty sending e-mail from Thunderbird. The limitation of data now allowed on Thunderbird is very limiting, so I have had to learn from my son how to save my e-mails in a separate folder on my pc at a too regular basis.

What has motivated me to write again after so many years, is that it appears that there are changes coming about by Thunderbird that have been recently advertised, and I was rather hoping that there would be some developments that could make my life easier after such a long time.

You don’t have to be a techie. to recognise that I am not, so if anyone has the knowledge and patience to help me out, I would be very grateful.

Accidently deleted my main inbox/profile from Thunderbird when I was trying to delete a different account. I need to restore the profile, emails that were in that inbox, etc. What is the best way to do that?

Dear Community I have had an gmail account on thunderbird for years. In/outbox etc details were still on thunderbird but when checking account details in Thunderbird all info was there as normal.... but.. in "View password"..there was no details at all for this gmail account - but were there for other accounts.

Went to the gmail app and tried login...my email and password are correct...login was ok. I deleted the gmail account from thunderbird and tried to to do "New, Email Account." and entered my gmail account details correctly and hit Done when green gmail 'configuration" is "found".

Then I get a google window to sign into my gmail email account - it has correct email address shown.. I enter correct password and get this message.

"400 Thats an error... The server cannot process the request because its malformed. It should not be retried. Thats all we know"

Thunderbird email setup then shows a yellow box that says "wrong configuration... etc"

Checked in gmail settings and imap is ticked - pop is not. Also checked Gmail "Connections to third party apps and services" and Thunderbird was enabled in April 2021.

Does someone have a fix for this?? or... where have I gone wrong?? Cheers M.

Hello. Last week I changed my password (using Mozilla Firefox) and since then I have not been able to log in to my email via Thunderbird. The password is definitely correct. When I log in via the Mozilla browser, there is no problem. Thank you. Slawek

Hi

I cannot setup my email:(

I have put in the details as attached images.

The auto config did not work either.

The error I get is, "could not log on, maybe a configuration, email or password issue" which is completely useless

When I'm composing a New Message and I press ENTER to start a new line, the text reverts to the smallest size, but the option to make the text larger is greyed out. So I'm unable to make the text larger. To resolve this I usually copy the previous line and the line that I want to add into a Notepad file, then paste it back into the new message.

See Image.

Thanks, SweetTasha

I've Thunderbird 115.13.0 on Ubuntu 22.04 and I have my email which is configured properly automatically by Thunderbird for IMAP and SMTP servers from Microsoft outlook office 365.

However, now it has problem for both IMAP and SMTP (I can authenticate with OAuth2 in a login page inside Thunderbird without issue).

The issue is:

``` The mail server for account xxx@yyy responded: User is authenticated but not connected ```

My email belongs to an organisation and I don't have admin rights to change anything to authentication.

Any helps would be appreciated for that issue.

Tunderbird fails to open at a early stage (loading the default inbox) and is then unresponsive. How can I extract messages, pesumably from the profile, please. Widows 11.

Keep getting a problem with Gmail, since it went to the new security login OAuth2, it works for a little while with all the permissions granted etc, then I come back a little while later, I get gmail popups (see images) asking to give permission for TBird to access gmail mail/contacts/calendar etc. I was getting a bit fed up with it so removed the gmail account on TBird - BUT I still get the popups even though I deleted the account... It's driving me nuts (win11, desktop etc). I haven't got a lot of hair left, so any help would be gratefully received!

Dear Mozilla Support Team, Good afternoon. Thank you for your message regarding for titled topics.

Regarding the connection with so-net mail has been solved. That is amazing for me that you attached Japanese so-net documents to me, it was sustainable a lot. After choosing POP3, I could see the Thunderbird mail this morning as the default setting.

However, unfortunately I cannot transfer existing my Thunderbird mail profile data import to my new PC yet. If you know the reason why, plase advise it to me, as I attached screen shot. Thank you and best regards, Minoru Takimoto

Hello, I hope you're having a good day! I am unable to reset my password following a data breach. I have read that I need to change it on the Mozilla website. Are you able to help me with this? Thank you! Best regards, Nicky

The problem is that incoming messages are turning into something like this. This is a very urgent matter. The account is configured using IMAP. When this email is forwarded by another employee, everything is fine, but only this inbox receives such strange messages.
