Thunderbird Support Forum

Three days ago, Thunderbird started to give me a "Sending of password for user xxx.xxx@gmail.com did not succeed. Mail server pop.gmail.com responded: Username and password not accepted.

I checked that it was accurate in the Saved Passwords panel and it is. I've entered it manually and still get the error message.

When I log onto Google from any browser with this account, it accepts the password. I can then access my gmail account with no trouble. My Firefox password manager shows the same password that is rejected by TB. My Gmail Android app on my smartphone and tablet also accept my logons with the same password. Only Thunderbird doesn't. I've tried deleting my pop.gmail.com login entry and re-creating it under the xxx.xxx@gmail.com account.

I had a Google Security warning 3 days ago, so suspect somebody might have hacked the account, changed the password, but didn't save his new password anywhere, so I have no idea what new password he might have changed it to. I am going to try changing my entire Google password and see if this will allow me to reset the TB password, but any other suggestions would be appreciated.

I have several other gmail accounts on Thunderbird and all of my accounts use the same passwords set for their accounts.google.com under the separate gmail addresses. How do I find out what to do to fix it?

Hi,

My old Gmail account works in Thunderbird 68.12.1 (32-bit) with no problems, that is, it sends and receives mail. Now I decided to add another Gmail account to Thunderbird. It receives mail without problems, but it can't send mail. If that matters, I have total 4 accounts in Thunderbird (the other 2 aren't Gmail accounts and they're working).

Both accounts have identical settings:

1) both are Gmail mails, that is, mail address is like name1.name2@gmail.com and those mails aren't new (I've had them for several years, but in Thunderderbird was using just one of them).

2) the option for "Less secure app access allowed" is turned ON in Gmail account security

3) POP mail server settings: Server Name: pop.gmail.com Port: 995 Connection security: SSL/TLS Authentication method: Normal password

4) SMTP server settings in Thunderbird: Server Name: smtp.gmail.com Port: 465 Connection security: SSL/TLS Authentication method: OAuth2

So why my new account can't send mails with Authentication method: OAuth2 (it can only send mails using Authentication method: Normal password).

Isn't that the opposite of what should be happening? I thought that Gmail was supposed require OAuth2 method. Anyway, what I'm missing to make those accounts identical for Gmail?

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?

I have recently changed from using Microsoft Online to GMail service (not by choice). I now have a problem in that I cannot send emails from TB because TB still wants to sign in to the Microsoft SMTP server, not the GMail SMTP server. I have tried various strategies, including delete / recreate account, but TB insists that I need to log in to the MS server. So atm I am receiving / viewing emails in TB (because I prefer TB), but sending / replying via GMail. Please help.

Hi, TBird stores my email addresses and passwords - So why should Google get involved? Today I can't get to my Gmail accounts because a window pops up - << One account. All of Google.

Sign in with your Google Account...  >>

Why should I trust Google with all my eggs? The way they ask is aggressive even - a big white window, not a lot of text, no Help, no explanation; with no Hide/maximise/close window controls.

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?

How do I export my private PGP Key from the new Thunderbird Version? I created it when 72.2.1 was released and I want to backup it, but I have now idea how to export it. I am using MacOS.

Thank you!

This was never an issue but the last 3 months all emails from a particular sending keep getting sent to spam. I have added the sender to my contact list. I keep marking the emails as "not junk" while they're in the spam folder and they get moved into the "inbox" but the next one that comes in goes straight to spam. What else can I do to get them to stop going into spam? I would think that after 3 months the adaptive system would have learned to adapt.

Hi I use Thunderbird with 3 gmail accounts. I have recently changed my Google Account password on two of the email accounts. Thunderbird recognises one of the changed email accounts but, in respect of the other, I get a message that the login to the imap server failed. When inputting the new password, I keep getting the same error message. I went into Thunderbird passwords. On one occasion the imap server for the failed email account appeared in the list and I changed the password shown there to my new one. No success. When I returned to the passwords screen, that imap login had disappeared.

On my iPad all 3 gmail accounts are recognised without a problem.

Thanks.

Before dinner Wed nite (EST), I could check my GMAIL emails (imap.gmail.com) just fine. After dinner (must've been something I ate?), TBird now keeps asking me for my password when I try to 'Get Messages' or 'Send Messages'. When I put in the correct password, it doesn't accept it. I have checked the CAPS lock key, too. I even tried an old password.

The 'good' password works to get me into Gmail online, so I can view all of my Gmail Emails, but TBird is so much better or course. I can use the GMAIL app for my IPad and everything is fine, so at least I can see my messages.

I CHANGED NOTHING!!! The Passwords show in my password manager.

As an aside: Before all of this happened, I had been noticing that, since updating to the newest TBird, everything is super super slow. When I would type something it'd take 3-5 seconds to show. Plus, it now takes 'forever' to load up.

Just discovered that my Address Book has been wiped out! Is this some type of virus?

BIG THANKS TO THE PERSON WHO HELPS.

I posted a question and got one answer that does not help.

Verizon.net is now handled by AOL. In 4 days Thunderbird will not support it unless I comply with the new AOL security settings. I am having trouble doing that unless I delete the Verizon.net account and re-install it thereby losing all my Sent messages. That will be painful. AOL did give me an App Generated Password to use but I cannot find the place in Thunderbird to add it.

The one answer* said if my incoming and outgoing servers are imap.aol.com and smtp.aol.com it would be easy. The server settings are: pop.verizon.net and smtp.verizon.net

Any other suggestions?????

• Thank you SFH

Cannot access Yahoo mail for about two weeks now with T-bird. I am using the latest version with inbound.att.net and outbound.att.net with Oauth2 selected. I have an Oauth password from AT&T, when I try to use this I get a pop up that asks me for sign in credentials. When attempting sign in it says I need to enable cookies. (Firefox) I have given "cookie" permission to https://att.com, https://yahoo.com, https://login.yahoo.com. Can't get past this, any suggestions or additional permissions I might try?

I'm using hmailserver on a standalone Server 2019 (not a DC). It's for internal mail only, and that's it. So set up for SSL/TLS on port 465 and STARTTLS on port 143 using a self-signed e-mail cert. There's no problem receiving, but unable to send e-mail with a a warning that the certificate can't be verified. Tried to "solve" the problem and I was unable to after a few hours. Overall, I'm not yet convinced where the problem is - the hmailserver program or the Thunderbird program. So time for a new approach. Instead of trying to figure out why it won't work, what can I do to "make" it work? So with a new approach I decided to see if I could find a work-around. I did.

Navigate to C:\Users\<pofile_name>\AppData\Roaming\Thunderbird\Profiles\<profile_in_use>\ and open the Cert_Override.txt file using notepad. List there you will see the data for your self-signed certificate, but only for the incoming mail port. (Port 143) in my case. It will look something like this: my.mail.server:143 OID.2.16.840.1.101.3.4.2.1 CE:D6:4C: (buch of key gibberish after this)

Copy the above to a new line, and the only thing you need to change is the port number. In my case, I changed it from port 143 to port 465 since that's what I use on the hmailserver program for the SMTP port. Then save the file. Now now the file looks like this: my.mail.server:143 OID.2.16.840.1.101.3.4.2.1 CE:D6:4C: (buch of key gibberish after this) my.mail.server:465 OID.2.16.840.1.101.3.4.2.1 CE:D6:4C: (buch of key gibberish after this) Now you can restart Thunderbird and when you check the certificate exceptions you'll see the cert listed twice - once for the incoming port and again for the outgoing port. I now have no problem receiving "or" sending e-mail through my end-to-end encrypted hmailserver program.

I wanted a phone no. so I could call. Today Thunderbird decided to no longer accept my password and there is no route for getting to Thunderbird to find the problem or get another accepted password. Bruce Lowrey. brucelowrey@comcast.net, but it does not work since Thunderbird is not accepting my password. 816-254-8105

My company uses PGP for all email and Thunderbird is the primary client. The new version 78 with PGP enabled appears to force encrypting subject line. This breaks all our filtering. Enigmail allowed us to disabled subject line encryption.

Is there an option to disable this while keeping PGP enabled?

Thank you,

I have just upgraded from 68.12 to 78.2.2. I used Enigmail but I have migrated to the built-in openPGP. Everything runs as it should.

But it seems that my passphrase has been saved. In the old Enigmail, it used to ask for the passphrase regularly, which I found safer.

So in Thunderbird 78.2.2, is there a way to avoid the saving of the passphrase, or to define how long the passphrase should be saved (e.g. 15 min, session...)? If not, should I then use a master password to protect it? I cannot find the passphrase under saved passwords, so I am not sure where it is stored and therefore if the master password would protect the passphrase.

Thank you!

I had been using Thunderbird + Enigmail + Gpg4win + Yubikey to sign and encrypt my emails and the setup worked pretty well. However, after updating to Thunderbird 78, which has built-in OpenPGP support, I'm having trouble to configure it to work with my Yubikey.

Following is my GPG keyring:

PS C:\Users\DDoSolitary> gpg -K --keyid-format long C:/Users/DDoSolitary/AppData/Roaming/gnupg/pubring.kbx

sec# ed25519/50268311C7AD3F62 2017-09-02 [SC]

     688E1D093C3638F588890D4450268311C7AD3F62

uid [ultimate] DDoSolitary <DDoSolitary@gmail.com> uid [ultimate] DDoSolitary <DDoSolitary@outlook.com> ssb> rsa4096/A7A1C4F99C807AD4 2019-03-21 [A] ssb> rsa4096/F091309F5863457C 2019-03-21 [E] ssb> rsa4096/90A79E1B71BC0CB1 2019-03-21 [S]

The master key is kept offline and the subkeys are stored in my Yubikey and are used to sign/encrypt messages.

What I've tried:

1. Enable "mail.openpgp.allow_external_gnupg" according to https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards 2. Add my key ID to in the "End to End Encryption" section of Account Settings (I've tried key ID of the master key and the signing subkey, both of which don't work) 3. Write a new message, check "Security > Digitally Sign This Message", then click Send.

I've checked that the GPGME library (C:\Program Files (x86)\GnuPG\bin\libgpgme-11.dll) is in the PATH environment variable. As Gpg4win only provides 32-bit builds, I also reinstalled the 32-bit version of Thunderbird.

Unfortunately, I always get "Unable to send the message, because there is a problem with your personal key. The configured key ID 'xxx' cannot be found on your keyring."

The new Thunderbird 78.4.0 (64-bit) with built in end-to-end-encryption does not work correctly. My keys never save in Thunderbird. But, all my keys are in the OpenPGP key manager. The security tab on a new email is greyed out. This is also greyed out in settings. I can add the key into Thunderbird OpenPGP key manager, but the keys never saves in Thunderbird Please see screenshots

I look forward to your reply

Kind regards Budda

Hi,

i can not send encrypted messages anymore. TB says the recipient has no matching key, but in the key-list the key is clearly shown.

How can i debug this?

Thanks!

Thunderbird outgoing email no longer working have checked both settings with email provider and thunderbird. Called and talked with tech support with email provider. They claim it is a thunderbird problem. Tried new port number. Know that my settings are correct (verified by email provider). Fails do to unexpected error. Can send email via webmail.
