Right click not working on spam email

Lately I am getting spam with from addresses I can not use the right click on to copy the email from address for reporting purposes. I have to use the More option, View Source and then search for the From address and copy it from there. Can this be fixed?

I saved off the source if someone wants to see it.

On Saturday morning 27 June 2026 I tried to login my Orcon email account via Thunderbird (which I have been using for a long time). But my login didn't work, I got a message saying "login to POP3.orcon.net.nz with username habitation failed." On 30th June 2026 I reported the problem to Orcon.

Orcon gave me the following settings for Thunderbird. I have done that and even made a new account: Incoming Server Type: IMAP Mail Server: imap.orcon.net.nz Port: 143 SSL: Off Authentication: On (username and password required)

Outgoing SMTP Server: Mail Server: smtp.orcon.net.nz Port: 25 SSL: Off Authentication: Off

Since then I have spent many hours and going around in circles with Orcon's Technical Support to resolve this, but no luck. They blame Thunderbird. I used Thunderbird Troubleshoot Mode. The message that comes up reads: login to server mail orcon.net.nz with username habitation failed. Please can you check that your server settings above are correct? And if there is a bug? Irma

Each time I open TBird, I get a message at the bottom left of the screen telling me that TBird has deleted X number of messages. I do not want TBird to ever delete any messages. How do I turn this automatic delete function off?

I am running Thunderbird on a new Windows 11 laptop. When I download new messages and try and open them my laptop locks up. Anyone else have this problem? Thanks Dave

I get this message when I try to send emails Sending of message failed. An error occurred while sending mail. The mail server responded: mf-505: Sender Policy - Relay Denied. Please verify that your email address is correct in your account settings and try again. How to I find out this information

Yesterday I found that I can't send mail using Yahoo.ca. I was able to get my wife's computer working by sending an email. A message came on the browser and I logged in to Yahoo. She can now send email. When I tried the same thing on my computer, I get a message "No apps available". I have spent hours trying and can't get around the message. The simplest test is as follows:

• create a new profile, and open the new profile
• enter my name and email address, and continue
• I get a message "Configuration found in Mozilla ISPDB." It uses SSL/TLS and Oauth2
• I hit next. Yahoo opens a page in my browser to log in. I enter the password and the security code sent by text
• The browser sends a message to allow an app. When I allow it the message "No apps available" appears as shown.

The release notes on Thunderbird are Version 153.0 | Released July 21, 2026 For now, I can use a second account on gmx.com to send mail, but prefer to use Yahoo when it works. Any suggestions?

I have two domain accounts; crumpcorp.com and dannycrump.com with GoDaddy. I have two E-mail accounts; [redacted] @crumpcorp.com and [redacted] @dannycrump.com. I use Thunderbird desktop Email. Thunderbird has the ability of use filters to perform automatic actions on messages received. One of the filters is “Forward Message To”. Unfortunately, attempting to forward messages fails. Thunderbird displays the following message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

Please help with this issue.

I have a rather intriguing issue with the message editor which isn't a problem but puzzles me.

I monitor a number of email accounts. When compiling a message using one particular sending account the line spacing in the editor is reduced, as in the second attached image. If I use any of the other accounts it is correct, as in the first image . In each case the line spacing of the message that is actually sent is correct.

It's obviously not a big issue, but I'm struggling to understand how the editor can change depending on the sender account. Any ideas?

I put emails from my Inbox into the delete box. After a while I delete these but I have just found that they remail in the All Mail Box. How do I delete these emails from my acccount on Thunderbird? They do appear in my online Gmail account as far as I can see.

I am unable to access my mails on Greenby with Thunderbird and I suspect the password is incorrect. I can read my mails on the Greenby server and know the necessary password but cannot work out how to enter this into Thunderbird! As I am no expert, a simple guide would be most appreciated! Thanks in advance. Roy

How to avoid: Sending of the message failed. An error occurred while sending mail. The mail server responded: message rejected .

AUP#SNDR. Please check the message and try again.

No matter how large or small the Thunderbird window is, I can't see all 3 of the Address Book columns without expanding the window to take up the entire laptop screen. The column width seem to be locked in at a pre-set number of pixels. I've tried to grab the edges of the columns to reduce their width, but they don't seem to be active. What I would really like would be for the Book to adjust to the Thunderbird window's width, or at least let me scroll between the columns. As it is, I can't view or edit the entry details of a individual listing in my Book without greatly enlarging the whole window.

Any ideas on changing these column widths would be appreciated. I've got Windows 11, and TB version 140.13.0esr (64-bit).

Thanks, Grasses

I am trying to switch from the ESR channel to the release channel. I have Thunderbird 143.13.0esr and am trying to upgrade to 153 (not ESR). When I upgraded, Thunderbird could no longer find the inbox for my primary email and I had to restore both Thunderbird 143.13.0esr and my email library from my Time Machine backup.

I am seeking advice on how to do some cleanup of an inbox anomaly so that I can install 153 without losing my inbox.

Details follow:

My primary email account has had an oddity in Thunderbird for years in which I have two inboxes: an active one with lots of email messages as well as subfolders, and an inactive one which is empty and no subfolders. I have tried deleting the inactive one by selecting it in the sidebar and choosing File, Delete folder, but that command is gray.

By poking around in my Library, Thunderbird, my profile, Mail, my pop account of interest, I discovered the inactive inbox is named Inbox and has only two files, "Inbox" and "Inbox.msf". The active inbox is named "Inbox prev" and has these files: "Inbox prev", "Inbox prev.msf", and a folder "Inbox prev.sbd" which has a bunch of files and more subfolders. All of my four email accounts have multiple folders and subfolders, but I was able to identify both my primary email account and my active inbox from various folder names that were unique to that account and inbox.

Today I followed the following procedure:

1. Quit Thunderbird (and all other apps) 2. Force a Time Machine backup 3. Download Thunderbird 153 for English, US 4. Verify the SHA hash 5. Install Thunderbird 6. Verify the signature 7. Launch Thunderbird

Both my active and inactive inboxes in my primary email account were gone from the Thunderbird interface. I checked my library and the files appear to still be there.

I proceeded with the following remediation:

8. Restore Thunderbird 143.13.0esr from Time Machine, replacing the 153 version 9. Restore the Thunderbird library folder from Time Machine

I launched Thunderbird and my inbox has been restored to the UI, but I am on the esr channel and not the desired release channel.

Is there any kind of manual cleanup I can do to get rid of the inactive inbox, rename the active inbox from Inbox prev to Inbox, and then re-upgrade to 153?

I can see that there has been a reply or a messages was forwarded and when I right click for the menu "Open" may not even appear at times. When it does appear "Open in Conversation" is not always presented as an option even though there has clearly been conversation as I can locate reply's in the Sent folder. Sometimes it's there but when selected it opens a tab that only shows the email and none of the conversations. It's hit and miss and I can find no rhyme or reason. Any help would be greatly appreciated. Also, I would love to Testflight Thunderbird on Apple. Thanks, Sue
