I am having a major issue with Thunderbird not saving Outgoing emails in Send Folder with IMAP setting.

Having three mailboxes two are set to IMAP and the third set to POP3. The IMAP outgoing mail creates an alert that mail was sent but copy not placed in your Sent folder due to network of file access errors.

Outgoing mail in POP3 save immediately to the Sent folder.

I am using the latest Thunderbird update:

• Server Type: IMAP Mail Server
• Server Name: IMAP.kinect.co.nz
• Connect Security: SSL/TLS
• Authentication Method: Normal Password

Outgoing Server [SMTP] Settings:

• Description - User name
• Server Name: smtp.kinect.co.nz
• Port: 465
• Connection security: SSL/TLS
• Authentication method: No authentication

Note: Authentication was changed form Normal Password in order to gain some traction on the issue during trouble, cause and correction actions.

Addendum: The PC was fitted to Starlink https://en.wikipedia.org/wiki/Starlink in preparation for use as sole source for internet connection. That was abandoned due to email issues.

Hello, I am trying to send and email with script and 2 photos but every time I try to send it I get a very quick flash of a small box with writing in it but it disappears right away, and my email is not sent. Why is this happening and how can I correct it so my email will actually be sent?

Thank you for any help you can provide.

Jean.

Can anyone please explain why, when I type an email and use Bold, Underline, paragraphs etc the program actually changes some text to symbols like asterisks & underscore symbol instead of underline etc that I did not enter and in general makes the body of the email look terrible when it is sent and printed out. I have tried typing the message in Word first and then copying to the email but it still seems to change it when the email is sent. Does anyone know why and can this be fixed? The last couple of emails I have had to prepare in Word, save as pdf documents and then send as attachments and this is a long and tedious process just to send an email message even if it is a long message. Thank you.

My name is graeme , my wife Olivia.

I have many many messages from various people; if I reply to a a mail from "fred", Thunderbird creates a mail:

to: fred@xxxx from: graeme@xxxx

I have several messages from my wife , that behave in this same fashion (ie , as you would expect) but ONE message, when I reply the message displayed in Thunderbird (ie NOT YET SENT, so no SMTP etc yet involved) says:

(it does NOT have a REPLY-TO header BTW)

to: graeme@... from olivia@.....

...I've search back though my mailbox and all the mails from my wife work as you would expect, bar this one ...AND ONE OTHER that I found:

This says:

from olivia@.xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

When I hit reply , it generates a message:

from olivia@xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

So the from and to in the reply are exactly the same as the from/to in the initial message (they are not swapped)

So, to be clear 99% of messages are fine, it's just one or two cases where I get this odd behavior.

Since I upgraded to version 140.7.1esr (64-bit) Eclipse, I have been getting intermittent problems with sending emails. My settings for Thunderbird are to not remember passwords between sessions. When I send an email the first time in a session the supply of the password to the prompt is fine and the email is sent. But when I then send another email I get the invalid password prompt. If I use Enter New Password and put in the correct password the sending still fails. Sometimes if I delay and resend the message which has been saved, the process does work.

Recently I have noticed some changes in the way my Thunderbird downloads POP3 messages. Previously, it would be common to ask for new messages once a day and receive upwards of one hundred of them. But in the last month, this number has been limited to about 35 at a time. If I ask immediately again, I get about 35 more, and this pattern continues as long as there are messages in queue waiting to be downloaded. I am not sure if this is due to changes in gmail, where most of my received messages originate, or to changes in Thunderbird itself, or to some sort of third-party hack. Now that I have trained myself to keep on asking until there are no more messages coming down, this change does not cause me much difficulty, although initially it sometimes caused me to overlook messages because I failed to keep asking as long as I should have. Apart from that, it does not seem to be harmful as far as I can tell. I'd just like to know if other people have noticed anything similar, and if anyone knows what is causing it, and whether it has some hidden advantages over the way things used to work.

So, from time to time I need to find a sent email, it is not in my sent folder, I check my settings and there it is, I then set it to use my sent folder on the IMAP server, this works for a while, but then seems the next time I want to find something in the sent folder it has reverted back. Any Thoughts?

No new emails appear to have been downloaded since 12.00 GMT on 27.01.26.

Size of file on disc suggests they are there but not displaying.

Downloads working fine on iPhone and iPad.

Neither plain-text nor HTML-signatures are being removed in replies, even though they are at the bottom of the email i'm replying to, prepended by the default -- tag on a dedicated line, as is the standard. I double checked that mail.strip_sig_on_reply is set to true. This happens on two separate accounts configured on my client. Thunderbird Version 140.6.0esr on Tuxedo OS (equivalent to Ubuntu 24.04)

I have 2 parallel accounts with the same ISP. As of 2 days ago, whenever I try to send mail, I get this message: “Sending of the message failed. An error occurred while sending mail. The mail server responded: Command rejected. Please verify that your email address is correct in your account settings and try again.” I receive mail as normal. Using the other address with exactly the same settings allows me to send normally as I have for the past ten years! Nothing appears different anywhere in the settings. There were no upgrades that I am aware of. I have since found that I can send from my basic little "travel" computer without issue. Any ideas? BTW, using POP mail settings.

TB 128 stopped downloading messages from 1blu.de on one 1blu account, another is working.

Switching to pop did not help, neither resetting password on server. Going back to imap did not help. Update to 140.7.1 did not help. In 140, TB connects, searching folders, discovers inbox, but no download of new messages. Inbox is abonniert (subscribed?) and messages are set to loaded to TB.

inbox.msf is updated today, the inbox has a date of Jan 26, latest downloaded email as of Jan. 21, inbox is 3GB and writeable.

In itself, the account at 1blu is ok: the release version (146.0.1) can connect and download messages dated until tonight (=right now).

1blu recommended to delete/reinstall the account but that would mean loosing tags and maybe xnotes.

Any help is appreciated. I write legacy and webextention addons for TB and can run test code in the console or in a temporary addon, if needed/helpful.

Thanks, Klaus/opto

I have been trying for days now to set up my Homail account into Thunderbird. It shows it there, but doesn't download any messages.I have tried every way I can to set it up, but, no joy. I even downloaded a programme suggested on Firefox, but that didn't work either. I also cannot find where to check the SMTP connections. I haven't had any problems with my Gmail accounts, they went straight in.

On first start of Thunderbird in the unified inbox there are sometimes empty messages listed with date of 1/1/1970 01:00.

When I click on any of them to view message, they always just blank empty body with no subject or sender. If I click on any other inbox, then go straight back to the unified inbox, the blank messages have gone.

I recently upgraded from v140-ESR to v147-Release and thought it may stop happening, but it still occurs sometimes.

Doesn't seem to be doing any harm but it's strange behaviour nonetheless, so thought I'd see if anyone else has experienced this or what you guys think could be causing it.

I operate a number of IMAP email accounts on Thunderbird. With just one, a load of my emails from my inbox end up in my deleted folder and I have to move them back again. I have set my deletion settings so that, if I delete an email, it is permanently deleted, so none of the emails I have deleted are in my deleted box. But it is still full up with emails from my inbox I don't want deleted. Any ideas how I fix this?
