Using Tbird 78.14.0 (64 bit) with Windows 10. I can no longer access the Page Setup screen properly. I suspect it's because I accidentally put a very big value in for the top margin. The print preview for even a short email says it's many pages, there's no text visible on any of those pages, the only part of the Page Setup screen visible is OK and Cancel at the bottom, and I can't get to the top of the screen. I've tried closing and re-opening Tbird to no avail. How can I get to the top of the Page Setup screen to fix the problem?

Yesterday Thunderbird worked just fine. This morning I tried to respond to several emails and got this error message: Sending of the message failed '"An error occurred while sending mail. The mail server responded: [VO=1] Message blocked due to spam content in the message. Please check the message and try again."

There was no spam in the person's email... just text.

Next I tried to send a freshly created email with just a YouTube video... then the last half of the error message said: An error occurred while sending: RBL restriction: Blacklisted by Internal Reputation Service - 195.181.168.179

What is going on??? The SMTP settings are correct: Port 587 STARTTLS Help!!

I am trying to whitelist a domain name. TB won't let me do that. This company has a plethora of emails. I don't want to whitelist every single one of them. That would take me days. It is impractical. I want to whitelist the domain name which is concentrix.com. I want to ensure that all emails coming from that domain name land on the inbox folder. How can I do that on TB?

How can I change the subject prefix (Re:, Fwd:, etc.) ? I would prefer "RE:" to "Re:" for my outgoing mails. "mailnews.localizedRe" handles recognition of incoming subject prefixes, but I found no pref for my outgoing mails. Thank you!

Need help setting up my domain name with godaddy and Thunderbird email client. need to get DNS Records from godaddy also. Having more trouble with this than I should, I think. I have already setup an email account on Thunderbird with earthlink/mindspring and icloud. No problems at all, in fact, both were very simple. But no so much with the domain name and godaddy. Any assistance will be greatly appreciated.

I am using Thunderbird 115.5.2 (64-bit) on an older iMac on OS 10.12. I have four email address accounts, all gmail, and using POP. I have stored emails I wanted to keep in sub folders in Local Folders. This has all worked well for years.

Yesterday I lost lost all content from some of the subfolders in Local Folders, while some retained some content and a few seem intact. I also lost most emails that had arrived in the inboxes in the last week. The folder pane still shows the accounts, with their own set of folders. As usual, the inbox folders are highlighted with the number of new emails downloaded from the Gmail server to each address, but I can not see them in the message pane, or find them anywhere else. I sent a test message from one of my addresses to another – It didn't show as sent in Thunderbird, but did go through the gmail server and the message count of downloaded messages on the recipient address went up by one, but I couldn't see the email. Then I tried clicking on the folder "properties" then 'Repair Folder' but nothing happened, although the information on that window showed the number of messages and MB that I would expect to be in that folder, rather than what was there, which presumably means they may still be in there somewhere? I would be very grateful for help – I'm not tech savvy and feeling completely lost.

Hello; Windows 10 & current version of Thunderbird. I am trying to add Messages Filters to filter out spam (getting more and more of that!) but the "OK" button on the add message filter is below the bottom of the screen. The window cannot be raised or resized to make the button visible. Photo below. Moving window does not allow me to raise window above top of screen. Keyboard (Alt-Enter) / Move will not work. Changed windows screen size just makes window larger but button still below bottom of screen.

Non-functional work around. Highlight Message name. Press Shift-Tab TWICE. Press ENTER. UGLY!

Tech since DOS 3.0

Thank you for your time and attention.

I am trying to import a backup of my gmail using using ImportExportTools.

What does this error message mean? Is there a corrupt email in my gmail? If so how can I find and delete it so I can complete the import, I think it was close to finishing.

2nd question.... After clicking OK on the error message I can select the local folder it was importing and I can see it is then downloading a range of messages with mention of their labels in the bottom of the window but the labels are not creating folders. Should I expect it to do that?

Our Thunderbird is set up with 2 email accounts - Gmail & Cox cable. Actually 3 as my wife also uses TB for her Cox emails. Cox is moving over to Yahoo. Not a fan of Yahoo. Eventually I will either set up another Gmail account (cox was for subscriptions or when a business needs an email address) and my has a Gmail already, but she does not use TB for that as for her Cox is her main email.

So can I delete our Cox emails thru Cox web email site without losing our emails currently in TB? And will that mess things up as TB sends and receives email from cox cable?

Any tips and suggestions much appreciated.

If you change your Thunderbird setting on your PC from POP to Imap, how do you change setting on phone if you are not allowed to change them? Do you have to delete existing POP account and setup/add the new Imap version. ? Can you also force stop the POP account and try to change settings that way?

PC = HP PHONE = Samsung Galaxy S23

POP E-mails stopped downloading on 1/27/25 in Thunderbird, AND Occasionally tries to download the same message repeatedly, WHILE defaulting inbox layout settings only on that e-mail account repeatedly after I correct it each time...

What is causing this?

I am running 2 e-mails from my own domain, and 1 Gmail all within Thunderbird. While the above problem is occurring in 1 of my own domain accounts, it ALSO began only selectively downloading messages in my Gmail in Thunderbird and in the other personal domain account (same domain as the e-mail with the above problem), but with no inbox layout defaulting.

Very weird. Please help if anyone has info on this. Thank you!

I also noticed in the past few weeks that Thunderbird began doing this defaulting of the layout of that one e-mail account then too after the 128.6.0 update, but now these other problems as of 1/27/25.

I am having an issue with retrieving my email in Thunderbird. On laptop, using Version 140.2.0esr | Released August 19, 2025. No changes were made to Thunderbird settings. The email is showing up in the Comcast portal, but for now having it forwared to a Gmail account. Tried changing password in Comcast (and in Thuderbird) to no effect. Tried deleting my Comcast email account in Thunderbird and re-adding it, but no change. Can send out email fine, just receiving it is the issue.

Interestingly, I use BlueMail on my phone and it, too, has the same issue and will not retrieve from Comcast. Thanks in advance!

For many years I have enjoyed using Mozilla Firefox Web Browser and Mozilla Thunderbird email client. Apart from the occasional glitch, everything has run well until I installed the latest Thunderbird Version 128.1 esr, earlier this month. I had used Message Filters to move inbox emails directly into my Local Folders. Now there is no option to either create a new folder or create a new sub folder. I tried to convert a little used Local Folder, and lost the sub folders. I don't know where they went and cannot restore them. Q1. I just do not understand how to use this new version. Do Mozilla have an instruction manual for using the V128.1 esr? How do I alter the previous version installation to be compatible with this one? Q 2. If, for the time being, I would like to stick with the familiar previous version, how do I do that? Mozilla are convinced V128.1 esr is a big step forward. I need your help to convince me to change and how to do it. Regards, Colin

I can't find a way to import the Inbox emails from older Thunderbird version to the new version. When I use the Thunderbird Menu>Tools>Import>Mail, I get a list; Becky! Internet Mail, Outlook and SeaMonkey, none of I which I use. I just want to import my old Inbox and Local Folders from the old Thunderbird I've been using for a decade. This should be easy. What gives?

This started yesterday. Opening Thunderbird I get a popup saying its from Yahoo and it has my Yahoo mail address on it. If I delete that popup by clicking the upper right "X" another popup takes its place. And so, and so on. One popup after another all for various Yahoo products. Meanwhile Thunderbird can not be used - can't write, can't send and can't receive anything on Thunderbird.

What do I do??? If I reinstall Thunderbird I will loose all my saved emails, and anyway will that work???

I have run my antivirus, checking my whole disks, and nothing.

How do I get rid of the Yahoo popups???? Please someone help me.
