Thunderbird Community Forum

Since Friday I have not been able to use thunderbird. I can open it but it wont connect to Virgin.com I have checked all settings (click on test connection it states good) then every five minutes when it try's to connect I get the following message (email address removed)

Login to server pop3.virginmedia.com with username ******* failed

I still get mail on my phone so it's down to a Thunderbird issue I believe. Tried to reinstall same issue, tried a new account and wont allow me to authenticate.

PLEASE can someone help - have a load of work to do but can't get on. Thanks in advance David.

Can't get rid of this spam: ecare.all.r@emailff.att-mail.com Unfortunately I clicked on it and multiple spam sites came up. I've tried the spam filter and it doesn't work. Suggestions?

This morning, my email Inbox is empty. I use Thunderbird for four email accounts, and three of them are fine, but the fourth one has an empty Inbox this morning. I didn't (intentionally, anyway) move the emails anywhere, and they do appear to be in the All Mail folder, so I didn't lose them entirely. But I keep my emails mostly in my Inbox and they aren't there anymore.

Any ideas what happened to make them disappear and how I can get them back to the Inbox?

Thanks!

I was adding some filters for senders to move emails to my local folders and such, and then I ran the filters. For whatever reason, when I ran the filters this time, thunderbird also seemingly deleted all emails from some of my web email inboxes. The only one that wasn't affected by this inbox wipe was my school email(gmail provider). How can I prevent this from happening again?

Thunderbird is downloading new messages but failing to display them.

Other functionality remains active, ie I can see and open messages, delete all the contents of folders, compose and send messages, but when the software downloads new messages they simply do not display and cannot be accessed.

Not sure if it's relevant, but the message INBOX count appears to be stuck at the number 59, although more messages than that have been downloaded.

Bizarrely this is the message displayed whenever I now open the Thunderbird application (it was there when the problem first appeared and returns everytime). Out of desperation I even made a donation in the hope it would release the messages!

Thank you in advance, Steve Davidson

When I attempt to send email I get the following message: Sending of the message failed. The message was not sent due to exceeding the allowed number of recipients. The server responded: Policy-SC01 You’ve reached your sending limit. Don’t worry, you can send again soon..

Hi,

I remember i tried 7y. ago a email certificate signed with SHA3, it was not OK.

I tried again now, and it is still blocked.

1) the certs can be added in the account settings > S/MIME for signature and ciphering, with a warning. 2) then creating a new email, the recipients certificates are not detected (while configured in another account on the same thunderbird client), and forcing ciphering is not allowed with the error message

"Sending of the message failed. This message cannot be digitally signed because the signing certificate selected in your End-to-End Encryption settings is not valid for this operation. (The certificate was signed using a signature algorithm that is disabled because it is not secure.)"

"Unable to save your message as a draft. This message cannot be digitally signed because the signing certificate selected in your End-to-End Encryption settings is not valid for this operation. (The certificate was signed using a signature algorithm that is disabled because it is not secure.)"

Even, when using only ciphering, and no signature in S/MIME.

The parameter mail.smime.accept_insecure_sha1_message_signatures do not change the bahavior.

-> Can Thunderbird allow SHA3 usage, please ?

Even if thunderbird does not want to generalize it, mozilla may create a parameter by default false

mail.smime.accept_sha3_message_signatures

"The certificate for pop.centurylink.net:995 is not valid for that server. Someone could be trying to impersonate the server and you should not continue."

when I set an exemption, the problem remains ???

HELP‼

Are there any •SERIOUS• “Thunderbird” savvy computer geeks in 155.0that could help me merge “old” user profile directories from *crashed* computer to a new computer without messing up either one?🙏

i used to do this stuff (with my eyes closed) but I no longer remember if I had breakfast today and they are my wife’s files! 🤬

I have new notebook computer plus the •entire• old computer data on a USB stick.

The issue is that the text I type into the top level of account settings, which has Account Name, and Default Identity, doesn't save. Initially I entered the email address and Thunderbird found the correct details, but I was creating seven new accounts and was going to come back later and fill in the details. However, the details on this page don't stick, wand it reverts to blank entries (as shown in the attached image), and each account's name defaults to the email address. It's awkward because if I create a new message it won't add a signature because that gets cleared with the other details on this page.

This might be related to an earlier question I asked Delete Account button doesn't work. since it's on the same page as the DELETE button. This suggests to me that there's a script engine that I'm missing on my PC. This is only a guess. I use Fire Fox as my main browser, and Vivaldi as a backup. As I say, this is only a guess.

Installed Thunderbird in August 26. Successfully added Outlook and Gmail accounts (send and receive)

On a roll I then tried to migrate from Plusnet to Greenby. Can successfully receive emails via IMAP.plus.net server. But could not send mails from Greenby (other accounts still OK)

Traced problem via forum query 31???? to inability to create a new SMTP server for outbound mail. After entering all data in the outbound server there is no response whatsoever to clicking add button (ie no error messages or servers added to SMTP list)

Then tried to delete the partially active Greenby account via clicking delete button in account setting window. No response. Account still present.

Does anyone have any suggestions to solve this before I try the doomsday action of deleting and reinstalling Thunderbird.

TIA Phil

I can’t receive or send email’s at all

      I entered my name in the dialog box in Thunderbird Mail which is supposed to change the blocks on “Enterprise policy” to pass. The block sign is still up.   How do I that.

I have a trojan in one of my emails. Every time I start TB McAfee catches the bug. I cannot find it. What processes does TB execute while loading. I want to be able to isolate the the bug. What tools can I use in TB to help with this.

Subject says it all. I installed Thunderbird maybe a month ago, because the web version of Yahoo email changed their interface, again, one too many times for me. I love the customizability of Thunderbird!!

If only I could get a handle on the odd checkbox behavior though ...  :-)

My Thunderbird (windows) is really not working, so I want to reinstall the whole thing. I have 4 accounts and a local folder. I don't want to backup all the profiles before reinstalling, as I am having an annoying issue with g-mail (I don't HAVE a gmail any more, but Thunderbird wants to login to gmail every time I open it). I only want to backup the "local" folder, as, so I want to reinstall the accounts one by one from scratch. In that way I hope, I can purge Thunderbird of the gmail. Now the question: How do I backup the local folder in a way that makes it easy to import it back after all the reinstallment?

I have Thunderbird 155.0 installed and also, TBSync + Google-4-TbSync to synchronise contacts between TB and Google.

However, I have just realised it hasn't been working for several months and TBSync is no longer compatible.

Are there other tools/techniques available to sync the contacts with Google?

Hello everyone,

Environment: Thunderbird 155.0 Windows 11 Pro, Surfshark VPN and Bitdefender Total Yahoo.ca POP3 account transaction@notice.aliexpress.com promotion@aliexpress.com

The Symptoms: Thunderbird stopped downloading emails from my yahoo.ca account with the message "Downloading message 1 of xx" where xx was increasing from one day to the next.

What I Have Tried: I disabled the antivirus and VPN without any result. I deleted the file global-messages-db.sqlite without any result. I entered the web interface in my yahoo.ca account and I saw that after the last message downloaded in Thunderbird there was a message from <transaction@notice.aliexpress.com>. I deleted the message from <transaction@notice.aliexpress.com>, restarted thunderbird and it started downloading messages until the next email from <transaction@notice.aliexpress.com>. I repeated the procedure several times with the same results: Thunderbird downloads any message except messages from <transaction@notice.aliexpress.com>. Other messages from aliexpress.com (e.g. promotion@aliexpress.com) were downloaded without any problems. The message download is blocked only when an email from <transaction@notice.aliexpress.com> is reached.

I searched for solutions on the internet but I didn't find anything.
