Thunderbird Support Forum

Hi.,

 Cox cable just discontinued their email server and moved all it's email accounts to Yahoo.

I had been using Thunderbird successfully with Cox for several months before this happened.

 I am able to send and receive emails now via my new online Yahoo server;  however I have not

been able to connect / use Thunderbird to send and receive emails since the Yahoo changeover. I have tried many things, but I either get a "failed" error message or a "timed out" error message. Yahoo support has not been able to figure this one out. They are hard to get a hold of and hard to understand (communicate with). They are overseas from the US.

 I appreciate any help you can offer.

Kind regards, Ken

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

According to Help>About Thubderbird the current version is 115. But searches in my browser tells me the latest version is 105.

Am I not searching deep enough?

Thanks, James

This is a recent issue. If I send an email with no images and no attachments, it copies the email into my "sent" folder with no problem.

If I send an email with even a small attachment...it sends the email, but "times out" copying the message to the sent folder.

I've checked the account/server settings, they are exactly as recommended. I've changed the sent files to "other"...no difference. I deleted and reinstalled Thunderbird...no change.

Ideas?

I just noticed that if I check the SENT folder, some of the emails I sent have this text in the body part.

"This is a multi-part message in MIME format.

Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit

[HERE THE CONTENT OF THE EMAIL I SENT]"

I'm wondering if they are sent like that, what the receiver will see and if there is a way to prevent it.

The email account is using IMAP and as far as I know it happen just to that specific email account. The emails are sent using Thunderbird. I'm using the latest version of Windows on a laptop. I'm using the following Thunderbird extensions (latest versions): - Compact Headers - Send Later - Mailmindr - Quicktext

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

I have TB 115.6.0 running on 3 computers (1 desktop and 2 laptops). On 2 computers there is a tiny icon on the right hand side in the menu bar that allows me to switch between the "new and improved" (but utterly horrible), side by side message list and the classic view.

On the laptop I am currently using to write this request, TB 115.6.0 does not have that wonderful little icon and I am condemned to use the side by side display or find another mail client.

Can someone help me find or restore that little icon that gives me a choice or alternatively lets me change the message list display back to its old useful configuration?

As an aside, why do software developers insist on making "improvements" that no one needs or wants?

Enabling my incoming emails. This has been failing for weeks. I reset my account with thunderbird and made a donation (thinking that was the problem) but I am still not receiving incoming emails. Tried and checked all my account settings - cannot find what the problem is. Please help.

I've just upgraded from TB 91 to TB 115 and unfortunately all my 'local' calendars are missing and I cannot add them back either. By local I mean 'On My Computer'. There is no problem with my 'On The Network' calendars, both existing and new ones can be added. But when I click New Calendar > On My Computer > (fill in name) > Create Calendar... nothing happens... no new calendar appears.

Recently, when I click on Get Messages to download email from Comcast server I receive error messages. One error shows "Login to server mail.comcast.net with username X?X?X failed. Retry, Enter New Password, Cancel".. Second error shows "Sending of passwowrd for user X?X?X did not succeed. Mail server mail.comcast.net responded: [AUTH] Temporarily blacklisted IP Address - try again later" I spoke with Comcast tech support and they, of course, gave me the standard line that I was using a 3rd Party App for email and they could not support that and I could instead use the email on line at my Comcast account site utilizing the antiquated Comcast mail options. They finally attempted to help and after they researched the issue they suggested I change the Server Name setting form 'MAIL.COMCAST.NET' to 'IMAP.COMCAST.NET' and changed port from 995 to 993. I tried making those changes and was not receiving the error statements. But I also was not seeing ANY email downloaded or message indicating TBird was login in the Comcast server. I then changed the Server Name back to 'MAIL.COMCAST.NET' and port back to 995. TBird then correctly downloaded dozens of emails. When I tried to same thing the next day, though, the error problems had returned. Finally, I was looking at Tools>Account Settings and selected Add-ons and Themes in left pane. I noticed Bitdefender Toolbar was enabled under Extensions so I tried switching it to disabled. Voila, the program would once again download emails. But a short time later another try to Get Messages resulted in the errors again. Can anyone answer with changes to connect properly to Comcast for email? Any help would be greatly appreciated.

I have a personal family domain, with email service - my provider supplies me with a number of pop3/smtp addresses.

I have a Thunderbird a/c setup on a desktop running Linux Mint, thgunderbird version 115.5.0 (64-bit) SUPERNOVA using one of the pop3/smtp addresses - husbandATmydomain.me.uk and I receive emails from another of the domain's pop3/smtp addresses, sent by my wife from a Windows 10 laptop using Thunderbird, under the address wifeATmydomain.me.uk

Her Thunderbird a/c is correctly set up in her Thunderbird, to use the smtp server for her email address, wifeATmydomain.me.uk. There are no other addresses or identities set up on her thunderbird account. My thunderbird a/c is correctly set up to use the smtp server for husbandATmydomain.me.uk and has several other pop3/smtp addresses able to send addresses using their own smtp servers.

In MY Thunderbird address book my wife's address is given as wifeATmydomain.me.uk, with the display name "wifefirstname surname".

When I receive an email sent by my wife, to me, it appears in my Inbox with the Correspondents column showing MY name not hers. This means I am constantly missing emails from her. because her name is not visible in Correspondents column, but mine is there instead.

The Reply To: and From: addresses are correctly given as wifeATmydomain.me.uk when I examine the receive email details. It is only displayed with MY NAME, in the Correspondents column in the Message list header pane, using Classic View. Everything about her emails displays correctly in Message View, using Full Headers display.

The only thing I could find in research was to make sure her a/c was using the correct smtp server. It is.

How can I fix this please?

Hello,

This is my very first post to a support community so please excuse me for any rookie mistakes and oversights.

T.B. 115.8.0 (64-bit) Windows 10 - IMAP settings with multiple domains and multiple accounts on each.

Problem/Issue: Most searches return the expected results, but in certain cases, and seems to affect mostly the sub directories in Local Folder (have not been able to replicate problems in strings found elsewhere).

Things I have already done: - Rebooted PC - Compacted the folder where the email resides - Repaired such folder - Confirmed that Global search is clicked for such folder - Opened the email to confirm that it does open and is valid (Remember that it's in Local folders so already downloaded)

E.g. Global search string "Re: New Project 25-301-623 needed into Swahili - word count 321" (which does exists in Local Folders) does not produce any results but (Deleted first character of the string) "e: New Project 25-301-623 needed into Swahili - word count 321" produced results for "New Project 25-301-623 needed into Swahili - word count 321" without the results for "Re:...". Additionally, no filters are displayed such as Location, People, etc. (Running the same search within the folder where it resides works fine.) Cutting down the string to only "Re: New Project 25-301-623" still does not find any results. Global search for string "Payable Summary for: August 2022", which resides in the same folder tested is found but no filter data available for Location, People, etc. However a search for "Project delivery for Job: 25-258-813" again residing in the same folder is found with Location, Account and People. I've tested same approach and tests on different folders to rule out Folder specific problems and behavior is the same problem.

Another example that might help in figuring things out. I tested a string of an email subject from an amazon order, which are long in nature do to # dashes, long numbers, etc. Performed a global search and the email was found but no Filters shown. Did the same search removing the end of the string "has shipped" and the email was found once again but with all Filters showing.

I hope I have been thorough enough. If any additional information is needed please let me know.

Thanks to all.

Hello, I have migrated my thunderbird onto a new windows system but I now get not automatic download of messages, the only messages I might get is if I close down Thunderbird and reopen. Get messages does not do anything - not even sure its attempting to communicate with server .

Is there anything I can do or change ? I have literally spent almost trying various things and I am the point of giving up and trying a completely different email client. There should be a seamless migration method but it appears there is not.

I am unable to copy text and paste from body of email in Thunderbird. I was able to in past versions. When I right click after highlighting text all options appear but does NOT allow to copy anything.
