Thunderbird-Hilfeforum

I'm using Thunderbird 115.7.0 (64 bits). Cannot send messages from my email account: katy.vandenhoek@gmail.com. It says it cannot make connection to server smtp.gmail.com. Receiving emails is OK. The other emailaccounts are working OK. Looks like there is something wrong with the authentification. Reïnstalling Thunderbird didn't help.

Dear Sir

I have an issue regarding receive and sending an email from my thunderbird account. So i just take a look for SMTP server port without editing any parameter, after that i try to login the thunderbird account using mail app on my Android. But i cant login on the android then my account on thunderbird PC is error. The error said:

Sending of Username did not succed. Mail server <my mail server> responded: Protocol Error. 14

Because of that error, i cant sending or receiveng email via thunderbird. Can anyone please give your advice to solve my issue?

Thankyou...

I used to be able to print my usernames and password list. I can only see it in an abbreviated form using the latest Thunderbird revision (with Microsoft). Any suggestions?

I recently downloaded and installed Thunderbird but forgot my primary password. Have tried the solutions available at the Mozilla website with no luck. I have also deleted the program and my Mozilla account, and started over from scratch. Still no luck.

I'm using Thunderbird for gmail in IMAP mode. In my IMAP folder, I have a Junk subfolder, and in my Gmail subfolder I have a Spam subfolder. What is the difference between these? Does Gmail determine Spam, and Thunderbird determine Junk? Are BOTH Spam and Junk used for the Thunderbird adaptive junk filter log?

Regarding having correct settings for smtp server...After working fine for a couple of years, in May my Thunderbird email client starting getting an error when trying to send email, requiring having to wait and retry multiple times to get the email to send without getting the timeout error. I spent a lot of time in May to resolve without success, then a lot more time this month. I have tried several different settings for "Authentication method" and "Connection Security" The smtp settings specified by my email provider, WOW, either don't match the Thunderbird options, or result in error. A different set of settings I tried seem to work, as well as a variation of what a WOW rep emailed to me in May. However I wonder if either of these settings cause any security issues to be concerned about--that is my main question now, since sending email seems to be working fine again.

1) The other week I set smtp server settings to Authentication method: Normal password Connection Security: STARTTLS That has been working fine for a couple weeks without error. However since WOW says they don't support STARTTLS is that a problem to specify those settings?

2) What one WOW rep specified in May on a screen shot with a handwritten note: Authentication method: Normal password Connection Security: None However when I specify "Connection Security: None" the only option allowed for Authentication method is: "Password, transmitted insecurely." Email seems to work without error with those settings. However is "Password, transmitted insecurely" a problem? Or is that OK? (Transmitted Insecurely doesn't sound reassuring!)

In multiple calls and hours of time with my email provider, WOW, they say they don't have any information about what the settings should be for Thunderbird, and despite their efforts have not been very helpful. Attached is some information they have provided on different occasions, or from the web site. Screen shot -- Outgoing Server (SMTP) Settings Standard POP3 Server information Email Server Settings

Gmail is going to require OAuth 2.0 sign-in SFAIK, that means I will no longer be able to access gmail with Thunderbird. Are there plans for Thunderbird to meet the OAuth 2.0 requirement?

I have been using Thunderbird for several years for my GMail accounts, and have always preferred to download my messages using the POP and SMTP protocols, rather than use the IMAP protocol which leaves them all on the web. Google now inform me that "To help keep your account secure, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password. Instead, you’ll need to sign in using Sign in with Google or other more secure technologies, like OAuth 2.0. What do you need to do? Email software, like Outlook 2016 or earlier, has less secure access to your Gmail. Switch to Office 365, Outlook 2019 or newer, or any other email software where you can sign in using Sign in with Google." These changes are due to take effect from May 30th. How can I prepare for them and still use the POP and SMTP protocols after that date? Is OAuth 2.0 appropriate?

The following Thunderbird error just started today for FOUR out of FIVE of my accounts. The error reads: "The stat command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded. Invalid credentials." Connection Security is: SSL/TLS Authentication Method is: OAuth2 Nothing was changed in several weeks.

I saw this error was posted before but NO ONE solved the problem.

Please help.

If I view an old mail, and if the remote contents are no longer available in the server, then I cannot know the contents. Whatif Thunderbird downloads the contents (when the email is downloaded) and includes them in message itself?

Hello, I received a Yubikey 5 and all is working fine using GPG with it, except integration with Thunderbird on Windows.

I followed this guide: https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards including 64 windows section

I was able to successfully send mail to myself, but then thunderbird failed at decrypting this message: Thunderbird is indicating that key is not available and I see no prompt from gpg-agent. Key is correctly declared as GPG external.

If I try to decrypt tis email by storing it on file and using gpg in command line, it works fine: agent is asking for Yubikey PIN and gpg is decrypting the message. But this is an awful workaround, not user friendly at all.

I also did sanity check by sending to myself a message encrypted with a key generated by Thunderbird: all is working fine, the message is decrypted within Thunderbird.

=> How do you make Thunderbird decrypt message encrypted with key stored in Yubikey? How do you make the gpg-agent called by thunderbird?

I have 6 gmail accounts which until last Thursday were all working fine on Thunderbird. However, I received an email for my main account from google telling me that they were switching on 2 step authentication, whether I wanted it or not.

After that imap stopped working for this 1 account. So I logged out of google for this account, and logged in again, using 2 step via phone. Still not working.

So I checked all my Imap settings with googles instructions, updated from the default smtp server, and still nothing.

Went back to google, and found I could switch off 2 step verification which I did. Thunderbird now partially works. I can download emails but when I come to send or save as draft, I get the error message as shown.

Hello!

After upgrading from a very old (but perfectly working) version of Thunderbird (24.3.0 on Windows 7) to 91.8.1 (on the same Windows 7 system), Thunderbird can no longer remember my passwords.

Apart from this everything in the new version works. Emails are retrieved fine when I enter the passwords manually.

Symptoms:

• always asks me for my passwords, even when I have checked the "Use Password Manager to remember this password" checkbox.
• no stored passwords show up in "Saved Passwords ..."
• When I try to set a primary password (I did not use one so far), I get an error "Unable to change Primary Password".

What I tried after searching for solutions:

• Remove files cert*.db and key*.db from my profile. Does not make any difference.

best regards

Edwin

Outgoing email includes the user-agent header. I would like to disable or modify the string for better security.

User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Thunderbird/91.8.0

Thanks...

Hi,

I, like a gjillion other people, received a notice from Google/gmail saying I'm likely to lose access through Thunderbird unless ... blah blah.

I was running TB v59. If stuff works I don't make changes. It makes life simpler. I did a heap of online reading and research about this and found lots of advice. I did the following;

• allowed cookies
• removed passwords
• changed authentication to OAuth2 in both IMAP and SMTP

I got the pop-up gmail/Google window asking me to login. My password is accepted. I am asked to allow access to gmail through Thunderbird. I allow. TB hangs sending security information and then crashes.

I assumed that it must be because I was on an older version of TB. I updated to the latest v91 and checked that the OAuth2 settings are as they should be. All good.

I got the pop-up gmail/Google window asking me to login. My password is accepted. I am asked to allow access to gmail through Thunderbird. I allow. TB waits of a bit and pops up a failure notification. This happens every time. If I click on "Get Messages" or I click on any of my folders, I get the gmail login popup, and I am asked to allow TB, AGAIN, and then failure. I cannot get past this.

I have done enough searching again, but I cannot find anything that helps. Can anyone here help with some guidance please.

I have uploaded shots of the various windows.

Thanks.
