Thunderbird: форум сообщества

Neither my wife nor I can access email on our respective PCs. This has been the case for four weeks. We can access email by our Android phones, but we really want to use our PCs. I've tried to resolve the problem and failed. Previous to this failure, I had an account with BT but this was transferred to EE. When I attempt to log in to my mail account, I receive the message "Could not connect ... :the connection was refused". I can also add is that in my Account settings, Outgoing Mail server I see a message "Connection to server mail.btinternet.com:465 failed."

ヤフーメールがセキュリティを強化する為に運用方法を変えたようでサンダーバードでヤフーメールの受信が出来なくなりました。 行った対策は行った順に ⓵サンダーバード側の保存されたパスワードの削除。再入力 ➁ヤフーメールのパスワード変更 ➂ヤフーメールの受信設定などの有効化 ➃サンダーバードの再起動 ➄サンダーバードアンインストール＆再インストール ➅アカウントの再設定 です。 ➂までで送信やヤフーメール以外のアカウントのメール受信は出来るようになったものの➄まで行っても結局pop.mail.yahoo.co.jpサーバーへの接続は出来ずエラー＆パスワードの再入力の無限ループでした。 又⑥ではヤフーメールのパスワードのみ旧or新パスワードどちらもパスワードが違うと弾かれアカウントの再設定が出来ませんでした。

対処法をお願い致します

Returned from a 1-month trip and my Windows11 would load - repair didn't fix it, so I had to reload Windows.

Now I'm unable to right-click on a photo and send it via my Thunderbird email. When I right-click on 'Send to', there's no email option showing.

Thanks in advance,

Scott

I have email [edited from public] @riverplazatravel.com purchased through Rackspace For days, on my emails through Thunderbird, I'm receiving emails but SENT emails disappear. They aren't showing in TRASH anymore, or SENT....they are disappearing and I have to check with my customer and they aren't receiving them. Big problem. Please help I've spent hours of research and dont understand much of that and so many are outdated. I've messaged and called various people. Your email was provided to me by Rackspace.

Emails we are sending to hotmail and outlook accounts are bouncing back and not sending? Is there a reason for this? Can it be fixed by changing server settings? Our hosting company said it is something to do with Thunderbird. Any help greatly appreciated!!!

This is what the bounce back email says:

recipients. This is a permanent error. The following address(es) failed:

This month I downloaded the current version of Tbird on a new computer running windows 11. Tbird receives all my email but can not send mail. I have an old computer running on windows 7 which has Tbird that was loaded at least 5 years ago. It receives and sends email without problems. The two versions of Tbird are using the same SMTP settings: server: mail.twc.com Port: 587. My email account for Tbird is slengyel@triad.rr.com

I also have a gmail account which receives and sends on both computers without problems. My gmail account is steve.lengyel9@gmail.com.

Both computers run through the same internet network.

Good morning. We have McAfee Ultimate with email scam protection. Our "att.net" email was hack 2 weeks ago. We have changed "att.net" passwords. We began to again receive emails. on 6/14/26 we began receiving this message when trying to down load emails - "unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox" We deleted emails found in the McAfee Alert mail box. We deleted the "att.net" email from McAfee and then reconnected it. we have gmail accounts and deleted trash. any thoughts for how to correct will be appreciated. jimw

I have created folders that I want specific emails to be put in when they arrive. But I don't know where to create these rules. Creating the folders is easy but how do I create a rule that tells Thunderbird which folder to put emails from specific people/businesses etc

Hi, I recently installed Thunderbird (POP account type), but it only downloaded about 3000 emails and then stopped, even though I have a lot more emails I would like to archive. It's been about 2 days since no more downloads have occurred. Ive got no way of knowing if it's a temporary pause or what the issue is.

I installed Thunderbird to archive my emails as I intend to delete some older emails from google work space to clear up space, but I want to still have an offline archive of these email.

This is a weird one, but as of a few days ago my email account has glitched and is sending an old auto-reply to every incoming email. I've ensured there's no auto-reply filter on my inbox at all, and have deleted all the templates, but for some reason it's still sending it to everyone.

Worse still it's now stuck in an auto-reply loop with the mailer daemon due to receiving a no-reply message, so my inbox is just filling up with endless 'Message Delivery Failure's!

I've also logged into the account via our hosting agent (123reg) and there are no auto-replies enabled there either.

Any help or advice very much appreciated!

Thanks, Kez

Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

I have an existing account on my old computer. When I put Thunderbird on my new computer, it downloaded thousands of old emails but would not open new mail. I uninstalled and reinstalled and it still won't show new mail.
