Thunderbird Community Forum

Yesterday I had to change my Spectrum email - I have an old road runner email address and swapped over to spectrum.net server from the old server. In this process I had to update my password to access the server.

When I updated per the instructions from Spectrum I was able to do a normal download into my Thunderbird inbox. This triggered me having to input the new password. I did check the box to update the password and save it. After the one time download I cannot get Thunderbird to download emails. I can send emails with no problems but cannot download. No way can I get a download - it does not on initialization, at the set time nor with the manual request.

Spectrum is no help - their web mail works and it's my problem. I realize this is an old system, legacy and all that - anybody got a magic fix?

Any idea on how I messed this up?

Thanks.

I have Thunderbird 146.0.1, using 6 email accounts with POP. Two questions:

1) Whenever I start Thunderbird, it retrieves only a subset of the email accounts which I have defined to Thunderbird. Some accounts retrieve ALL, and other accounts retrieve NONE. I also have the extension "Get All Mail" and when I click that it retrieves ALL the email, including the email that the Thunderbird base program didn't retrieve. How can I get Thunderbird to get ALL the email?

or alternatively...

2) Can I somehow disable the Automatic Retrieval of Email when I start Thunderbird? ... and rely solely on the "Get All Email" extension.

My inbox folder costently says it has more messages than it displays (I can see the missing ones by searching). I have tried repairing it, looking at filters, etc., but nothing seems to work. See picture. Thank you!

Hallo Zusammen,

bei der Neueinrichtung auf einem neuen Rechner fehlt mir der Ordner für gesendete Mails.

Ich habe die Anwendung auch schon komplett deinstalliert und wieder aufgespielt. Hat sich leider nicht geändert.

Was kann ich noch machen?

Beste Grüße

I'm not sure exactly when this problem started but it could have been when I had to move my primary email from Xfinity over to Yahoo. Also not sure if this started after a recent Thunderbird update. I can not send new emails nor can I forward old emails. Haven't tried reply but suspect it is the same. This is the message I get: Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again. All settings and passwords are correct as I can receive and send from all my different accounts using browser. I can send emails from my accounts, on my iphone, though not using Thunderbird on iphone. Account settings and passwords are the same on the phone.

Gidday I have been using Thunderbird for sometime and recently had to re-install the program so now I have the latest version of it installed but the program isn't removing the emails from the server. I can't locate the "delete from server" setting anywhere in the options. I have searched everywhere for an answer here and on the iterweb so would appreciate if someone could provide help please. cheers col

When I start Thunderbird, the same message is downloaded each time.

The status bar then reads "Downloading message 2 of 17," except that 17 is now up to 27.

Thunderbird remains in this state. No second message is ever downloaded.

When I close down and restart Thunderbird, it's Groundhog Day all over again.

Trying "Clear Recent History" has no effect on the issue.

I am on Thunderbird 150.0.2 (64-bit) on the release update channel. I'm on a Windows 11 HP Envy Laptop purchased in July 2025.

Mozzilla fonctionne mais je ne peux plus faire "envoyer" mes mails. C'est terrible d'autant que n'y comprends rien . Je rédige-sur la page "Rédaction" et après il n'y a plus de case "Envoyer." par contre je reçois les mails J'ai glané les infos au bout de 2 jours  : IMAP Je sui "Orange" Sortant SMTP/SSL/TLS port 459 Entrant SMTP/SSL/TLS port 995 et quelque part  : version 140.II.Iesr  ? Vous pensez que c'est grave ? ça fait 10 ans que ça fonctionnait

Firefox on this Windows 10 computer stopped providing an email Send option about 2 weeks ago. I still receive all messages fine, but must use Firefox on an older windows 7 computer to send emails. What can I do? Other internet receive and send functions are still working. The problem is only with email.

I have successfully set up 3 email accounts using my default domain. When I try to use an email account that uses a second domain I can't send or receive emails. This account required manual setup which I did but it does not work. My web hosting is with Namecheap and I do believe settings at that end are correct. Any help would be appreciated.

I have all my past emails in specific folders within Windows Mail currently. I have three email accounts. I want to set up Thunderbird and import all the folders of emails into it and access all three accounts from within Thunderbird. I have a Master computer running windows, a tablet and a phone. I would like each device to be able to access all the email accounts and the stored folder tree within Thunderbird. I would like the Master computer to be set up with POP3 for all accounts so I can archive those I need to keep. I would like the tablet and the phone to be able to see and interact with the emails via imap so that when the Master is opened it downloads everything for processing. Do I need to set up each device separately with accounts being either imap or pop3 accordingly? will they all sync together? Thanks for your input.

I have a request.

Please make it easier to send feedback to the developers.

I don’t want to have to log in to the forum every time just to ask someone who might not even be an expert.

I’m Japanese and don’t speak English, so the English forum is difficult for me to use.

It’s a hassle to have to post on the forum like this just because I can’t easily send feedback in my local language.

I have two pieces of feedback I wanted to share this time.

1. Sometimes when I open Thunderbird, I get an error message saying it can’t load because there are too many accounts. Is this because it’s trying to check them all at once?

Please have it load them one by one in order. Or, please add an option in the settings to do this.

2. Messages marked with “Re:” are replies, right?

Let’s say my account is “Apple.” If I reply from “Apple,” a message marked “Re:” should remain in the “Apple” folder. From the recipient’s perspective, replies to emails from “Apple” should also come from “Apple.”

However, there were emails where I was recorded as having replied from a different account, even though I don’t recall switching accounts when replying.

So, from the recipient’s perspective, it looked like the email came from a stranger, and they replied asking me to identify myself.

While it’s not impossible that I might have changed the address by mistake while half-asleep, I’m reporting that there were instances where I was recorded as replying from a different address even though I don’t remember making a mistake.

I just want to share a request and a report, so there’s no need to reply.

要望です。

開発者にフィードバックを簡単に送れるようにしてください。

いちいちフォーラムへログインして、素人かもしれない人に訊きたい訳ではありません。

私は日本人で英語が出来ませんので、英語のフォーラムも使いにくいです。

簡単にローカル言語でフィードバックが送れないから、こうしてフォーラムで投稿しないといけないのは手間です。

今回送りたかったフィードバックは二つです。

1、サンダーバードを開くと、アカウントが多いからロード出来ないとかエラーメッセージが出てくることが時々ありますが、一度に確認しようとするからでしょう？

一つずつ順番に読み込むようにしてください。 もしくは、設定で、そのように出来るようにしてください。

2、Reが付いているものは、返信したものでしょう？

アカウントがリンゴだとします。 リンゴから返信したら、リンゴの中にRe付きのものが残るはずです。 相手からしたら、リンゴから来たメールの返信もリンゴから来るはずです。

しかし、返信する時にアカウントを変えた覚えがないのに、違うアカウントから返信したことになったメールがありました。

なので、相手からしたら、知らない人からメールが来たことになり、誰だか分からないから教えてくださいと返信が来ました。

ねぼけて返信時にアドレスを変更した可能性も0ではありませんが、間違えた覚えが無いのに違うアドレスから返信したことになったものがあったことを報告しておきます。

リクエストと報告を伝えたいだけなので、返信は不要です。

I have just received the following message:

“Thunderbird Unable to connect to mail.madasafish.com. Please try again later. If the problem persists, you may have exceeded the maximum ...”

The message breaks off there and I couldn’t expand the window to see the remainder of the message.

Is there a problem with Thunderbird, as I only have 11 messages in my inbox? I normally have quite a few messages each day, but I haven’t received any since 2 days ago, September 16. I I can neither send any messages.

I would appreciate any help.

When ever I try to send an email list I get the reply below. Usedto work waht am I doing wrong??? HELP Sending of the message failed. An error occurred while sending mail. The mail server responded: <Reminder>: recipient address must contain a domain. Please check the message recipient "Reminder" and try again

Not sure what has happened to my PC but lost my Thunderbird app.

Reinstalled but cannot get my emails working again. I only get emails up to 13th May 2024; I guess when TSO Hosting finished?

I am now on 123 Hosting.

I have a note that SERVER for both i.e. Incoming and outgoing is:-

sxb1plzcpnl503269.prod.sxb1.secureserver.net (smtp as prefix)

Where and in what format do I enter theses server details.

I think I also need to get into cPanel but the URL I have will not work:-

https://sxb1plzcpnl503269.prod.sxb1.secureserver.net3 (:2083)

Sorry but I am confused; don't get old!

My outgoing server settings are correct, but I have not been able to send any messages since getting Thunderbird set up. I get a message that says:

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.chartermi.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

When I was setting everything up, the online bot "chat" instructions I was getting suggested that because my email account is so old (chartermi.net instead of charter.net), it may be causing some problems. However, I have not been able to find anything to address this, and that "chat bot" string has disappeared, so I cannot find it now.

Later this week I'll need to copy a bunch of old emails to someone (some of them received by me and some sent by me). Does Thunderbird have such a feature or is the easiest way to print them on paper and resort to snail mail?

I am no longer getting emails on Thunderbird on my computer though I do get them e.g. on my iPad, and I can email out. Is that a problem with Thunderbird or with Bell my service provider?
