Thunderbird Community Forum

Within the past day or so, which means 7-18-26 or later, some of my email messages on thunderbird for my pc have a "From" description that is not correct. I look at the messages, and the "From" is entirely different than the "From" description when looking at the email message list. I have never encountered this problem before. I'm using thunderbird 152.0.1 64-bit on my pc.

I successfully linked / synced the thunderbird calendar with the iCloud calendar. Calendar entries manually entered in iCloud or iPhone calendar are successfully synced and are visible in the thunderbird mail. The other way round, syncing the existing entries in the Thunderbird calendar does not work. They do not appear in the iCloud or iPhone calendar. Searching the internet, the specific Thunderbird or Apple help-sites did not provide an obvious solution for this problem. I went through all (or nearly all) recommendations given by Apple, no success to sync from Thunderbird to iCloud.

Any suggestion what to modify or adjust

Changed our broadband provider on Friday from PlusNet to EE and, since then, have been unable to reply to emails on my Thunderbird Mozilla account. I am still receiving them but when I attempt to reply I get the message:

"Sending of the message failed.

An error occurred while sending mail. The mail server responded: <pauline@dolhun.co.uk> recipient rejected - relay denied. Please check the message recipient "pauline@dolhun.co.uk" and try again."

Can anyone offer any help please? I am not very computer savvy unfortunately 'Regarding the question below which I have answered 149.0, to be honest I don't know which Thunderbird version I have but I had to fill in something!!

win10/tbird v140.12.1.esr wont d/l from yahoo. logon appears ok but the d/l bar starts & then just times out. This just started 3-4 days ago. gmail & fastmail ok.

In sending a new email, when I go to enter the "TO," various email choices pop-up - but not all are correct. How can I add and/or correct those popup choices?

BTW, I have a screenshot. How do I get it here?

https not recognized by Firefox in 151 Thunderbird on silicon iMac with Sonoma. Tried & checked many solutions with no results.

Firefox browser primary , always Nothing in Modified Important Preferences With Extensions off still a problem

Someone hacked my thunderbird account and I can't get to it. How can I find the password that is now associate with it? I was told the provider has to do that, but Spectrum can't do it. I tried independent software, but the password it recovered is an old one and it doesn't work. It doesn't show up in the list of saved passwords.

I get hundreds of emails a day, so setting an alert for incoming mail is not practical. Is there any way to set an alert for specific senders whose emails need to be res[ponded to promptly? I am not at the computer all the time.

This will make more sense if you look at the attached images first. If I create two one-hour appointments back to back on the same day--meaning the first appointment ends at the same time the next one begins (or with a 1 min gap), and then I look at my calendar in Week view, I'll see 2 full-column 1-hour blocks stacked one above the other as in the "1hr appt.png" attached. This appears to be the correct way it should appear.

But if the earlier appointment is only 30 minutes, they appear differently, as in the other image "30min appt.png". squeezed into two columns. I would like them to appear as a single, full column (as with the 1 hour appointments), which it does in the Day view.

Is this a bug? Can I change this behavior?

I have 3 email accounts which i unified. when log in I get prompted to enter password for all three accounts which I do, then I get prompted again to enter the password to all Password Manager to save my passwords which I do not want and therefore I uncheck it for all three; I then get prompted again for all three which I enter password, then I get imap login error on my main account which I click cancel a few times before it goes away,

I use Thunderbird portable. How do I fix this issue. it should be that one enters the password for each account once not three to four times. I do not want to use Password Manager to Save my accounts.

Also if ever I have to change password how do I do that? thank for your help.

I have the portable version, download from portable apps website.

Probably related to a Microsoft update, Thunderbird started asking for the password of my internet provider almost daily several weeks ago when sending or receiving messages. I am on Windows 11 and that is up to date.

I am getting the error "connection timed out to connect to SMTP server". I am running on Linux Mint. The same setting do work on MacOS so there is no wrong config or broken SMTP server. It was working well since a couple of years. I also tried troubleshooting mode but still the same.

The Inbox on my Thunderbird emails shows 224 messages but do not open. I have tried opening and deleting but to no avail.

IMPORTANTLY I am still receiving new emails.

hi :-)

My Thunderbird uses between 19 and 34 GB of RAM. It's cyclical (with a period of about 10 minutes).

What do you suggest?

Do I need to perform a performance diagnostic? https://support.mozilla.org/en-US/kb/profiling-thunderbird-performance

Do I need to follow all the steps listed on https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems#Diagnosis_Steps, or can I skip some of them?

I have been using Thunderbird for many years. I just got a new computer and installed Thunderbird onto it. I have several email accounts for personal, business and clubs so this makes it easy to keep track of. I have some gmail accounts and 3 different yahoo accounts. Now when I get an email to one yahoo account it prorogates to the other two. This never happened on the old computer do you have any idea how this happened, and more importantly, how do I stop it?

There are certain emails that I receive that are *absolutely known* spam. I want these (but ONLY these) deleted as they come in.

I understand that one need to tick the "delete" box in Settings, but this seems to giver Thunderbird the right to delete anything that 𝒊𝒕 determines is spam. I don't want that. I want ONLY my own predetermined spam to be deleted.

And by deleted, I mean just that. Thunderbird just piles them up in the Trash folder, and this gets to be a big pile. Because Thunderbird makes mistakes, cannot just let it delete everything it determines to be spam, and so I have to go through this long list of junk in the Trash folder, which is annoying (because there's surely a better way that no one has implemented yet) and time-consuming.

I've made my own "delete" filter. It runs first (it's the first filter in the list), "before Junk Classification" and "Getting New Mail". Anything on this list should be deleted, because that's the ONLY action I have in this filter. If you're in here, you're gone.

Except your not. The filter is (for some reason) NOT run when new mail arrives. Instead, I have to open the filter, and choose "run on Trash folder". Then it works. But is THAT the design?!? Why is it not deleting arriving mail that meets the criteria?

There is also the problem now (as spammers have gotten more proficient) of the random character string preceding the @, followed by a domain name that you dare not mark as spam (for example, yahoo.com). These random characters are indeed random, and constantly changing, so you cannot filter on the address. But it seems to me some bright person might come up with something like "if 'known domain' is NOT preceded by 'known sender', delete". (This would require a user [me] to be very careful, or I could lose a new respondent who is not spamming me.)

But the point here is this: Over time, I have a great "delete" filter. Mail that this filter catches makes NO mistake. I want these messages (but ONLY these messages) to be gone when mail is retrieved. I don't want them in the Trash. And I don't want to have to take the time to run that filter on the Trash, because no one has created an extension that allows me to do this with a single click.

I would pay/donate, for this capability. But I can't bring myself to donate, or pay, when I have to go through a big Trash pile full of mail that, according to my filter, I should NEVER even see.

Other suggestions entertained of course.

But I'm spending too much of my life dealing with things that should be automated.

Regards,
