Thunderbird Support Forum

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?

v115.7.0 I have been a user and contributor for years. OS is still Win7. I have had a IMAP connection to Comcast for years, now it will not connect. I have made sure I am using the correct password. When I start thunderbird, a secondary window pops up with the error message unable to connect. WEnt thru lots of posts but no results. One interesting said to disable IPV6 security option, but the way they described the fix was to access thry the EDIT menu then Preferences, but my system does not have Preferences under Edit.

I got a new laptop and wanted to set up Mozilla Thunderbird for an existing Gmail account. I tried several times, all failed, with a warning "unable to connect with server imap.gmail.com, may be userid and password are wrong". But I can logon to my Gmail account (with the same userid and password) on Firefox website and on my previous computer, so the id and password are correct). And I was able to set up another Gmail account on Thunderbird in this new laptop (so the version of Mozilla is not the culprit) with the same server settings (port for incoming and outgoing mails, authentication methods SL/TLS, O Auth2 etc). Will someone please help me?

I just recently downloaded Thunderbird after using Mac Mail for years. Mail suddenly refused to display messages and no one on the Apple forum could figure out why. So I was advised to download Thunderbird. So far, I'm not a fan. Here are my issues: 1. Unread messages in the Inbox are in bold. But the bold is so close to the normal font that I can't tell them apart. Is there another, better way to mark unread messages? A tick/check mark? A coloured background? 2. Messages are automatically organised into conversations. But when the latest message comes in, the inbox message doesn't go bold. So there is no way of knowing where to find it. I have to go through all messages that have a conversation (more than one message in the inbox) and find one where the latest message is in bold at the bottom. It's a royal pain. I see the number next to the account on the left, but nothing is in bold on the right. Grrr. 3. The conversations are the wrong way up. I want the most recent message at the top, not the bottom. I would actually prefer not to have them in conversations at all, just the most recent message, but I realise that is probably asking too much. 4. There is no number next to the Thunderbird icon on my desktop when I get a message. I used to appreciate this in Mail. It told me if it was worth going to my inbox. With Thunderbird I have to open the program to find out. Ok, that's enough for now. I'd better not get started on the shortcomings of the search function, or how to bring the unread messages to the top of the inbox list... There are just too many issues to address is one posting. Thanks for any help you can give.

I am assisting my friend Lindsay in aged care to enable him to continue to use Thunderbird for email. Currently TB will receive mail but unable to send.

This is complicated in that Lindsay is paying iPrimus.com.au a monthly fee to enable him to use an old email address xx@bluep.com. I can log in to the iPrimus web portal to send and receive xx@bluep.com emails, https://webmail.iprimus.com.au/?_task=mail&_mbox=INBOX.

I downloaded Thunderbird version 115.6.0 (64-bit) on my pc this morning and the Auto Set Up configured mail.bluep.com as the incoming (POP) and outgoing (SMTO) servers. Mail is coming in but not sending.

I changed the outgoing server to smtp.iprimus.com.au, default port 587 however messages still cannot be sent and Thunderbird shows that smtp settings must be reconfigured.

I spoke this morning to iPrimus Tech Support who advised the default smtp port should be 25, not 587. However I have found that resetting the smtp port to 25 does not enable emails to send.

Note that I have previously set the smtp port to 587 which enabled sending on non ISP connections. This ability would be required as Lindsay is using whatever Wi-Fi service is available in the facility.

iPrimus Tech Support have suggested I should contact Thunderbird (Mozilla) about this problem.

Can you advise Thunderbird server settings for this situation.

Thanks for you assistance. Regards, Peter M

I notice this subject has been mentioned prior, but I cannot find a resolve. Been using Thunderbird for a long time without issues, but last week it stopped sending and receiving emails through the Skymesh internet provider. Still sends & receives Hotmail/Gmail/Yahoo, but will not connect to any Skymesh accounts. Have reinstalled/updated, but no change. SMTP timeout and if I change settings I get the 10060 error. Could not even connect to their Webmail page either. If I turn VPN on, then I can access their Webmail page. Rang Skymesh, they poked around and said it was all this end and with Thunderbird. Seems an IP number change via VPN with Opera resolved the Webmail page access, but I cannot do that thru Thunderbird. Running Win 7. Anyone ??

When running Thunderbird in Dark Mode, the message pane (that shows the message when you select it from your inbox) still has a white background. This makes perfect sense, because a dark background can easily mess up HTML mails.

Which I know because the compose / reply window does have a dark background, making it all but impossible to read what you're replying to if it was a HTML mail.

I would like to set the view and reply window to use the same background. Can this be achieved or is this a bug?

I have been successfully using Thunderbird for many years. In the last year or so I have been noticing that occasionally one of my sent emails gets corrupted such that the email body starts showing html text and the email subject header is changed to another email header that exists in the same folder but is unrelated to the email body. When I check the corrupted email from the Gmail web user interface, the email is not corrupted. I tried repairing the folder but to no avail.

I attach an example of a corrupted email below:

From Content-Type: multipart/alternative; boundary="------------NlJPhaGMpTt1f7wbEHlOvxNE" Message-ID: <4bf83075-b571-4214-921b-09f4582e6e58@jesuit.org.mt> Date: Thu, 4 Jan 2024 10:25:56 +0100 MIME-Version: 1.0 User-Agent: Mozilla Thunderbird Subject: Re: Minutes of SCPC Meeting Content-Language: en-GB To: Charlotte Attard <charlotte.attard@staloysius.edu.mt> References: <AM9PR10MB487111674D307583B8DB6AD3D195A@AM9PR10MB4871.EURPRD10.PROD.OUTLOOK.COM> <AM9PR10MB487106F96E9E404BDA477808D167A@AM9PR10MB4871.EURPRD10.PROD.OUTLOOK.COM> From: Stephen Scerri <stephen.scerri@jesuit.org.mt> In-Reply-To: <AM9PR10MB487106F96E9E404BDA477808D167A@AM9PR10MB4871.EURPRD10.PROD.OUTLOOK.COM>

Yes Charlotte - please proceed - sorry for delay

Symptom:

1. TB stopped downloading new emails for one account on PC.

Solutions Tried without success:

1. Checked Email configuration and settings 2. Restart TB 3. Rebuild Global Database by deleting global-messages-db.sqlite file. 4. Delete Saved passwords. 5. Delete all emails on webserver dating back to when problem began. 6. Change password on webserver.

Additional information.

Current version of TB: Version 115.9.0 Windows Version: Windows 10 Home 22H2 Email Webserver: Ionos Email Protocol: POP3

Issue Details: I use TB on my desktop to manage many different email accounts. Some from Gmail and some from Ionos. Last week, TB stopped downloading emails from one of my Ionos accounts. It still downloads from my other Ionos account and my gmail accounts. I use Aquamail on my Android device and it continues to be able to download emails for this same account. Additionally, I have a laptop with TB and it continues to download emails from this account without issue.

If you need additional information, please ask. Suggesting switching to IMAP is not useful and not a solution to my issue. I respectfully request that you Please do not go there (been down this road before). I want to fix the problem, not go around it.

I've had Thunderbird for a long time, but today, when I opened it, I got the set up page. Both email accounts (earthlink and gmail) were gone, along with all the saved email folders. Running Lenovo PC, Windows 10, latest release of Thunderbird (115.7.0, 64 bit).

Also, I can't send emails through earthlink, Just get the "sending message" window (that never goes away).

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?

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.

After the last couple of Thunderbird updates, I have been experiencing a really frustrating issue that I can't seem to resolve.

Only when I receive emails from one specific recipient and I go to reply to them, the font size is suddenly really large, and the spacing between new lines is huge.

Even if I set the font options to the same as if I was replying to a different recipient or creating a new message, it still appears really large.

What's worse is even if I make all these adjustments and get the font size and formatting looking okay, the actual sent message is even more out of whack and has all these spacing problems.

Does anyone know what might be going on? No other mail client I use experiences this issue whatsoever, and this issue is only occuring with this recipient.

I've been noticing apparent duplicate messages within my unified folders inbox on my desktop recently.

Looking further I notice that one of my accounts has 'INBOX' as one of its subfolders which is where the problem appears to stem from. When I look at that account in isolation (ie not in unified folders) I can still see the inbox as a subfolder.

The subfolder 'INBOX' appears to be a duplicate of the account's main inbox (it contains the same number of emails), which may account for the appearance of duplicates.

At a guess this is probably related to inadvertent moving of folders. I find that when trying to use the scroll bar (to scroll down the subfolder list), if the mouse strays slightly to the left it will pick up a subfolder and move it unintentionally. This can cause all sorts of problems with disappearing emails and the folder structures showing differently on different computers.

In this case the duplicate email problem only happens on my desktop. On my laptop I can still see a subfolder named 'INBOX' but it shows as empty and I don't see the duplicate emails in unified folders.

It would be really useful if Mozilla could introduce a 'confirm folder move' feature as that would eradicate inadvertent moves.

How do I resolve the apparent duplicate emails on my desktop? I am somewhat reticent to delete the subfolder 'INBOX' for fear of the potential consequences. . .

Since some time when I start up Thunderbird I get a popup:

"Add Security Exception" + "You are about to override how Thunderbird identifies this site"

In forums it was stateed this can be due to the antivirus program. I am using Acronis Cyber Protect Home. I closed Thunderbird, pauzed the real time protection and started up Thunderbird again: this did not solve the issue: I still get the pop up, see image attached.

Is there a way to analyse the origin of this pop up? What's triggering this pop up in Thunderbird?

Thx!

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.

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 seen numerous posts on this forum involving the "Leave Messages on Server" option in the server portion of the Account settings. Many of these posts include responders stating that this option does not apply to POP servers.

If this is correct, why does Thunderbird even include this setting for an account that is explicitly designated as a POP server/account? This is an invitation to confusion and misunderstanding; I have been a victim of this. It seems to me to be a no-brainer to change the code to remove this option from these POP accounts.
