Thunderbird Support Forum

I have an email account with IONOS and my wife has an account. We have had these accounts for several years. Recently my wife can not send email. We are configured the same and I do not have a problem. Server: smtp.ionos.com Port: 587 (tried others at IONOS support request) Security STARTTLS Authentication: Normal password. When she tries to send or forward with a simple text (one letter or larger, it does not seem to matter). She gets the following reply: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Transaction failed Reject due to policy restrictions. For explanation visit https://www.ionos.com/help/index.php?id=2425&ip=198.177.53.191&c=hd&r=0MQ4Bx-1rqmFh0x4l-00ErW3. Please check the message and try again." When trying to go to that web page, it does not exist. I have gone to IONOS support and we have both looked at the configuration and can see no differences between my set-up and hers. I have deleted all email address from her machine and reloaded Thunderbird (115.9.0), restarted her machine and added back her email. Same results, she can receive but not send. If she uses her phone, it works, and if you go to the IONOS web site and use there service it works. I'm at my wits end and can not figure it out. I have also opened an incident with the IONOS Postmaster, which I think is their second level support. Please help.

Hey there Team!

So I flipped my table because of the new Outlook update and I'm beyond frustrated.

Not only it does not show the unread email count but also stopped working for my work email, making me miss a serious meeting!

This is ridiculous!

So now I'm transitioning to Thunderbird however, my Inbox is showing the total amount of emails. This is not what I need. What I need is the unread amount of emails.

On top of this, if I minimize the email, the Inbox amount count merges with the amount count of Sent Items. This is not what I need either... What I need is to solely have the amount of unread emails.

How can I achieve solely unread email count with Thunderbird?

Please keep me posted as I'm losing my last screw over setting up something as basic as this. -Val

I use Thunderbird as a central repository for 5 different email addresses. Recently 1 of them stopped getting Sent messages that were created on Webmail or my Phone. I used to work fine, now it doesn't. This account is the only one I have that is set to POP3; the others are IMAP.

I'd change the settings to be IMAP but don'e see how to do that. And, I don't want to lose any messages and would like to capture the ones that have not been captured.

Any thoughts?

Hello, For some reason, over the past couple of months I have been searching for varied emails and they are missing! At one point, I found that some had been put in an archive folder (that I did NOT set up) and they were recent emails. I removed them from the folder, placed them back in the regular inbox and deleted that folder. When I could not find another very important series of emails today, after searching numerous ways, I looked in the server and missing emails are there. I did look at a number of email threads where other people reported similar problems... but couldn't figure out what applied to my situation and how to fix this. To show a specific example, I attached two images ... the first is my Thunderbird email account that shows one Email only on Feb 18, 2024. The Juno server image shows 7 emails on that same date, four which were important contracts that were sent to me. Can you please help me locate and retrieve these and other missing emails? Thank you very much. Ms Randy Rosette

I've got a Fastmail account, and have set up CardDav according to Fastmail's guide to get set up with Thunderbird.

Once my contacts synced, I was unable to see my contact lists in the Thunderbird contacts sidebar, nor can I add a list (the button is greyed out). Is this a known issue? Is it Fastmail specific, or a CardDav thing?

Hello! I am facing the issue with time zone translations. Here is what I do. First, I create event on web-interface of the google calendar. That account is linked to TB's calendar. This calendar has settings for my timezone as in the first screenshot, that is GMT+3 for Kyiv, Ukraine. It is actually GMT+2 + daylight saving hour in effect. Country is also set to Ukraine. Next, my Windows 11 system is set to set time and timezone automatically, region - Ukraine. It displays UTC+2 Helsinki, Kyiv,... I guess it's Windows settings display quirk, because time is correct and WSL console shows

~$ date -R Thu, 18 Apr 2024 18:59:25 +0300

My TB's calendar is set to have system's timezone as in 3rd screenshot.

Now if I see my event in TB calendar, it is placed one hour later, say 9 am event starts at 10. So reminders also come hour later. Also strange thing is that event properties in TB show correct time like 9:00 till 10:40, but for some strange timezone Europe/Zaporozhye, as in 4th picture.

However, if I set TB's calendar manually to Europe/Kiev (which should be Kyiv, but that's another story), then events are shifted hour up to their right place, 9 am. So this is my issue: when I set calendar forcibly to Kyiv timezone, it does translate it right. When I ask calendar to rely on system's timezone, which indeed is also Kyiv, then I get one hour behind.

When I answer an email TB adds Re: (or Fwd: ) in the subject line which I have laways found annoying. My previous email client allwed me not to have this happen. Is it possible to stop this?

It is possible I have asked this previously, but if so, I cannot find this and have received no replies. My apologies if I have!

I am an e-mail packrat.... I have a pop e-mail but keep years and years worth of old e-mails (inbound and outbound) some with big attachments. My backup for the few e-mail accounts I have within my profile is approx 13 gigs. I've moved machines... and currently running Ventura on my imac.

I have to force-quit all the time to get my e-mail working again. It hangs-up.... sometimes will recover... but then... I type a few words or maybe sentences... and back to HANGING-UP again. Sometimes after a Force-Quit... it will behave for awhile. Other times... it takes 4-5-6 force quits in a row to get the program working again. Been having these issues for months... and have taken out all the add-ons etc.... HELP... pulling my hair out! Thanks

Last week, sometime, I received ALL the emails, that have come into my "mailbox", from about the time I purchased my latest computer, several years ago. There must be hundreds, if not thousands, of the little critters. All arranged alphabetically, starting with the letter "a". So far, the ONLY solution I've found from "Thunderbird Help", is to 1. Open inbox 2. Select [left click] one of the repeated emails. 3. This high lights the email in BLUE. 4. Select BOTH "CONTROL & A" KEYS at the same time. 5. This highlights the WHOLE PRESENT page of emails in BLUE. 6. The instructions then say to press the "DELETE" key. 7. Question is- IF I PRESS THE "DELETE" key, will that just delete the emails on this page, OR delete EVERY email in my entire "inbox"? The only OTHER remedy I've tried, is to send the unwanted emails, ONE at a time, to the "TRASH" folder, then empty the "TRASH" folder, when I get 10-15 emails in it. That could take a VERY long time. Awaiting your suggestion[s]-Joel Payne P.S. Might this happen again? If so, it may be time to go back to Carrier Pigeons.

je n'arrive pas à envoyer des mails avec ma messagerie sur Thunderbird, mais j'en reçois. L'icone en forme de cadenas est barré de rouge, cela m'affiche qu'il y a un problème avec le chiffrement des messages. Puis, que la connexion au serveur sortant SMTP free.fr a expiré ...

Que puis-je faire ?,?

Thunderbird auto updated to 115.10.1 and now it is behaving strangely.

1. The Message Filter has "Junk" at the bottom of the list of filters and anything that is not sent to a folder gets sent to the Junk folder. Instead all the junk is going to the Inbox.

2. Folders that have new email show up in blue highlighted folder as they should. But if I select those emails and read them, they remain highlighted but without the blue color.

3. Sometimes when I delete an email after reading, it deletes for a moment and then returns to the folder as unread. Multiple attempts to delete fail.

I have latest Thunderbird version (115.9.0 64bit) on fully patched Ubuntu 22.04.4 LTS.

I'm trying to get it to display Day-of-Week for old messages - is this possible? I have tried all sorts of combination as detailed HERE to no avail.

I'd like concise instructions on how to do this (if it can be done). I do not believe trying a new profile will work as I need to test this for old messages - at least for messages older than a week.

From the link above, I can the Day-of-Week to work for the current week - but that only displays the day and time. What I'm after is as shown in the attached Outlook screenshot. Also see the closest I can get that to match in the Thunderbird screenshot.

Hi folks, I am wondering if there is a way to change the behavior of the pop-up reminder window in Calendar. When I have missed reminders (e.g. a task set for today at 8am and it is now 9am), the task is visible in the reminder window that pops up every time a reminder is active. This is fine. But if there is a past reminder (not resolved), every time I add a new task (or edit a past task) to the calendar, the pop-up reminder window opens and comes to the front. Let me describe the example: I missed (knowingly) a reminder at 8AM. Now, at 9 AM I need to add 3 new tasks to the Calendar. After setting (or copying, editing) each new task, the pop-up reminder window is focused on the front. Can I change this behavior so that the reminder window only pop up when the reminder is due and not in the case a new task is set up or old one edited?

Already invested time creating some html code for email signature on thunderbird. Wanted to create something prepared for dark modes on IOS. Everything was fine until I detected on IOS (dark mode)some white rectangles outside my email signature code. It´s a problem that I cannot solve because it´s outside my code, and I´m wondering if you are already aware of this issue.

In case you want to test my code on a Thunderbird HTML email signature and see the result on an iPhone (dar mode), you can get it here: https://codeshare.io/dekBnR

Junk, Bin, Deleted confusion in email account There is confusion in Settings regarding Junk,Spam, Bin,or Deleted. When setting up Spam checks it refers to Junk folder where I have customarily used Spam folder and or Deleted/ Bin folder options which am now not able to set in the options available. Is there any way around this. I use' Ubuntu Linux' and 'Android (Gmail')? Thankyou Walter Reed t.walterreed@gmail.com mail@walter.plus.com

An IMAP mail system is configured on a server running Debian 12. While there are never any problems via webmail, reception and sending work occasionally via Thunderbird 115.9. Even in "Troubleshooting Mode" it doesn't work. The server has good hardware characteristics and there are no applications that can slow it down, nor do I think it is a firewall problem or incorrect parameters otherwise it would never work. The error is related to timeout reaching the server. What can I check to find out where the problem is?
