Thunderbird: форум сообщества

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?

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: <X@dolhun.co.uk> recipient rejected - relay denied. Please check the message recipient "X@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!!

After being on the right side for decades, the Options button on the remote content box was moved to the left side. How does this improve accessibility for the average user? Is there a rational reason for doing so?

I have over 200 email accounts in Thunderbird, and I am getting constant pop-up error messages that say: "Не удалось открыть индексный файл для 'Входящие на [email]'. Возможно, произошла ошибка на диске или полный путь превышает допустимую длину."

I don't need help fixing the emails themselves, but I need to permanently disable these pop-up alert windows because I will soon have over 2000 accounts and I don't want 2000 errors popping up.

I am using the latest version of Thunderbird. I have tried looking for "about:config" or the "Navigation Toolbar" to change the settings to "false", but my interface is heavily customized and I cannot find the menu or the address bar. I need a step-by-step guide on how to disable these error alerts, preferably using the Windows Registry or a configuration file if the menu is hidden.

TalkTalk have outsourced their email to Everymail. We use Thunderbird as our e, Mail client on a pc. We have stopped getting email and can’t send any for a week now. Do I need to reset the server names suddenly.

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.

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.

With a new Thunderbird installation on Windows 10 Pro, I attempted to import my profile data from a Postbox on another machine. The process failed, citing two errors (see attached screen shot), EmptyDatabase Error: "blocklists/addons-bloomfilters" has not been synced yet Uncaught NS_ERROR_FILE_NO_DEVICE_SPACE: Component returned failure code: 0X805200010

The profile being imported is pretty large -- around 20Gb, so I wonder whether I have surpassed some capacity limit. I was doing this via the Import Tool on the Tools menu.

Porting my legacy mail folders is crucial. Any help would be greatly appreciated.

I have frequent problems with message filter settings and these problems have been occurring through several of the last Thunderbird versions. All message filters frequently lose "Move message to.." information. "Enabled" check boxes become unchecked "Run selected filter(s) on:... " specified file keeps changing.

I have been a Thunderbird user for many years, although I stopped updating with 102.15.1 (64 bit) as the new features and benefits did not provide a benefit. In the past few months, emails in my Inbox have disappeared, without being manually deleted. Typically the Inbox will keep emails from today and dated back to about six weeks earlier. Everything else is gone but still on the Rackspace ISP. I have Thunderbird running on two PCs (office and home), one iPad and my iPhone.

My account settings are IMAP, SSL/TTS, and message sync don't delete anything.

I have reviewed suggestions online regarding fixing this; including reindexing, changing settings, etc. but nothing has worked. I know that I can create local folders and save a copy there but I did not have this problem before and it is inconvenient to have to save copies, then remember to look at the saved folder instead of the inbox. According to the tech folks at Rackspace the issue is either within my system setup or some change to the Thunderbird program (although I am still running 102.15.1). My preference is to restore the program to its original functionality instead of creating work arounds. Any advice is much appreciated. Thank you.

I am plagued by demands that I allow Thunderbird to "permanently delete all" my email from Gmail. Why would I want to do that????? I'd like for Thunderbird to be able to compose, send, receive, and delete emails in Gmail, but not permanently delete all of my email there. What can I do?

Goodday,

Unfortunately I could not add a screenshot to this message. Under my account [redacted]@zonnet.nl there is a "Postvak IN". This means inbox. In this inbox should new mails appear. Right now there comes nothing in it. However, two lines below there is suddenly another "Postvak IN 22". New emails appear here now. I already tried to drag this inbox into the inbox under [redacted]@zonnet.nl but that doesn't work.

New emails now appear with a yellow bar: The text in the yellow bar at the bottom says: (I translated)

No unique identity was found matching the sender address. The message will be sent using the sender field and the settings of the identity Martin Belonje <[redacted]@zonnet.nl>.

To my opinion this has to do with the fact that the inbox has moved from its original position.

I hope you can help me out.

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

As of July 1, I no longer have access to my school account. It was a gmail account that ended in .edu. I have new email account that end in gmail.com When I open Thunderbird it asks me to sign into the deleted account which I no longer have access to. I can receive email in my new accounts but am not able to send email from them. I need to disconnect completely from my old school account but do not know how to do this. Thank you.
