I ran into an error on my Windows 11 PC. If I add an attachment via the system menu called up by the right mouse button, the size of the attachment is displayed in terabits and cannot be sent :-)

Blocking remote content by default is a very positive security feature. But needing to add each and every email address individually is NOT optimum and wastes a lot of time. We really need a method to globally allow remote content from specified domains. For instance, it would be handy to allow remote content from any/all email from IBM, but I certainly don't want this for gmail.com addresses. This seems like a very simple improvement to code.

I am not receiving emails and when I try to send an email I get a warning "Sending of the message failed.Peer’s Certificate issuer is not recognized.The configuration related to smtp.themessagingco.com.au must be corrected" I have made sure that the account information for incoming and outgoing mail is correct, but that is the limit of my understanding of what I can do. How can I correct this problem?

I maintain a "Favorites" folder view as those are the folders I use 95% of the time and I have a very large number of historical folders I need to keep around but don't need very often. Trouble is, when I create a new folder, the creation dialog doesn't offer the option to make the folder a favorite so that it disappears after creation. I have to switch to the "ALL folders" view and then right click on the new folder and check the "favorite" box and then go back to favorites view.

It would make life so much easier if there was a favorite checkbox on the creation dialog.

Thank you.

My service provider is QX.net which uses Magic Mail web email. I have Firefox 115.ll, 64 bit. I have Thunderbird 115.11.1, 32 bit.

The Magic Mail on my Server shows 253 unread messages. I have identified some of those 253 messages in my Thunderbird folder and they have been read, and are shown as read in Thunderbird. There seem to be 3 different dates involved. This is a concern as it is unacceptable not to receive all of my messages.

Please advise what I can do to address this so that I receive all my messages and so that when I have read them they are shown as "read" in Thunderbird and in Magic Mail.

Thank you so very much for any help.

Hi. I have 3 e-mails. recently I could not receive on another e-mail. I called my cable tech. he said that thunderbird hadupdated and some users had problems. He had me change my port to 578. I did and now the same e-mail will send but not receive. so three of my e-mails will send and only 2 will receive. I am very ignorant with computer use. I use a flip phone for travel. thanks dan

I am running 115.4.1 (64-bit). I noticed fairly recently that my main gmail account is not downloading the latest emails. I went to "Help", "About Thunderbird" and got the following error:

Update failed. Updates available at https://www.thunderbird.net/

I'm including a screen capture of the error.

Am I supposed to simply download the version at "https://www.thunderbird.net/" and then run that?

Thanks for any help.

HI

Outh2 Saved Password entries is being removed automatically after few months in password manager. It is asking again to Re-Authenticate. After authentication, It is getting removed again after few months. Please help.

I have a notification set so that I know when I've gotten new email. In the last month or so, AFTER I've closed Thunderbird, I still occasionally hear the notification that I've received new mail. How can that be when I've logged off and closed TB? What is causing this?

Thanks for any info/help.

Email from a trusted address over past decade is suddenly going to Junk as of today. Cannot see how to whitelist the Sender, and googling the question tells me to go to Tools>Options, however Options does not show in the Tools menu.

Hello, The Optimum SMTP is recently rejecting emails I am sending from one of three Optimum email accounts that I have. When using the one account I get the following rejection notice:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 6661A65F0037E564). Please check the message and try again.

This only occurs when I use Thunderbird to send messages. If I use Outlook on the same computer, I do not get the error. Previously, I was getting the error on all three accounts, but when I upgraded to 64-bit Thunderbird, the problem went away. Of course, I called Optimum and they said that the problem was on my side and were not helpful. They also don't take any responsibility if you don't use their web interface.

I would appreciate any ideas that anyone has on what I could try to eliminate this problem. Thank you.

Recently the email display has been changed and not by me. At present I cannot receive emails as previously. Also I wish to revert to the previous display of my emails if possible. I can access email via the email.telstra,com site but I wish to stay with Thunderbird. I also do not get emails to my mobile as before

This has probably already been asked, but I can't find anything related to it. Ebay sends email from members that looks like "randomxyz@members.ebay.com". I would like to add the domain "members.email.com" so email from ANY member will be whitelisted and have remote content displayed. If this is possible, how do I set it up? Thanks in advance.

Hi Everyone. I'm sure that Thunderbird used to have the option to show conversations (received AND sent messages) in folders especially useful in the Inbox. However I can;t see a way to enable that in the current version. I know I can go to conversation view in the context memory but it seems crazy that is an option by context but can;t be set as a default for 'normal' viewing in folders - all I can set is to see half the conversation with the trail of received messages but not my replies intermixed with them so I see the whole conversation. Am I missing a setting somewhre? Thanks fo any help.

My wife & I have the same PCs running Windows 10 & Thunderbird 115.11.0 (32bit).

We have a hosted web-site that also supports email, and we each have an email account (eg neddy@goon.com.au & minnie@goon.com.au). I've checked that both our POP server configurations are identical but despite that about once a week minnie@goon.com.au receives a warning to add security exception but neddy doesn't. This started happening two weeks ago after a years error free running.

The host has checked that goon.com.au has a valid SSL certificate, so what could be causing the discrepancy and how do I set about fixing it please?

I’m not able to download any of my emails. This is the message that senders who try to email me receive.:

“A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

  laurie@scottspencer.net     LMTP error after end of data: 452 4.2.2 <laurie@scottspencer.net> Not enough disk quota:     retry timeout exceeded”

I searched online for troubleshooting guidelines and did everything suggested that I found. I also uninstalled and then reinstalled Thunderbird. None of those things that I tried worked. I’m also not able to delete any messages. When I try to trash them, they just pop right back up.

This is my primary business email account and I would appreciate any help getting it up and running as soon as possible. Thank you so much!
