Forum Bashkësie Thunderbird

Hi,

I am facing an issue with Thunderbird.

I integrated my email address but there problem is the new message is giving "Undelivered Mail Returned to Sender" but I can reply and receive the emails.

Please guide me about it.

Many Thanks

One of my two gmail accouns has suddenly become impossible to access (cannot receive, cannot send). T'Bird produces an Authentication has Failed notification, after a Google Window headed "Sign in to Mozilla Thunderbird Email" which refuses to go away. Clicking on the 'help' or 'privacy' options in that google window produces no more than a blank window but then "Sign in to Mozilla Thunderbird Email" reappears a few minutes later. My other gmail account doesn't have this problem, so I assume it's not gmail but it's T'Bird.

What's going on?

(BTW signing into this Support resulted in an email "New sign-in to Mozilla Support" warning "New sign-in to Mozilla Support to Firefox on Windows 10". Trouble is, I'm on Windows 11. Trivial maybe, but telling maybe.)

ALERT ! wish to report an avalanche of emails from godaddy that are overwhelming my email box Tons of email under different names are coming from @registry.godaddy every day, the Junk filter is bypassed. A robot must be sending these one-liners using the flood volume as an attack. HELP!

Hello, I have problems signing in Thunderbird, it asks me for a password and though I am sure I enter the correct one it does not give me access and there is no way to put a new password also so how I am supposed to use Thunderbird again. I can do that with roundcube but Thunderbird does not give me access and to be honest I am a bit frustrated.

I have the most recent updated Thunderbird, I wish to delete a email account, however under settings Account Actions is absent. I have tried searching for and answer but no way to remove it so far. I have used Thunderbird for near 10 years and usually there is the Account Actions menu item. I see all settings its should be right under the item Return Receipts. But nothing is there.

Thank You for the help.

I've lost my password to log into Thunderbird. There is no provision to change it, and it wasn't saved by Thunderbird password manager. There MUST be a way around this problem. Please help.

In Thunderbird I'm wondering why when I flag an email red as 'spam' (and delete it) it doesn't automatically block the email address from repeated future spam attempts?

Hello, I'm not very computer savvy so don't understand why this is happening or even what a blacklist is. I've attached screenshots. I tried to google what to do but don't understand the complicated things posted. Any help would be greatly appreciated.

I've been using TB for years with an AT&T account on a Windows 10 desktop. Two days ago all was working well sending and receiving. I stepped away for an hour (without obvious updates or changes) and surprisingly it didn't work, with TB asking for a password but not accepting it. I deleted saved passwords and tried multiple times, even changing my AT&T email password twice. I could access the email account directly through the AT&T website using those passwords.

I spoke with an AT&T support rep and he had me delete the account in TB. I did so but now can't reestablish it. I've repeatedly tried to add a new email account using credentials I know are correct, trying numerous POP3 and IMAP protocols, all without success. When TB probes the AT&T servers it says it finds those parameters, but then when it checks the password it fails, simply giving the vague message "Unable to log in at server. Probably wrong configuration, username, or password."

I've spent two days researching this problem and trying proposed solutions such as disabling firewalls and anti-virus programs, clearing Windows and internet caches, deleting saved passwords, etc. I was able to set up the account using Outlook on this computer, and if this continues I'll unfortunately be forced to abandon TB and move to Outlook or similar as a substitute. Advice would be appreciated!

After the latest update: Every time I send a message and have selected at recipient, the program searches for a cetificate, allthough encryption is swichted off. A box appears for each recipient for about a minute, unless I stop the search (see image). Essentially, the program acts, as if I had selected encryption. This was newer an issue before latest update.

I was subscribed to a large distribution list, but then unsubscribed. But I didn't unsubscribe. So I subscribed again, but was soon unsubscribed again! My email address and password may have been hacked. So I logged into my Comcast ISP and changed my email password. Then I started Thunderbird, and as expected, it asked for my password, and I gave it. My email came up. I tried sending an email and it asked for a sending password. I ignored it, but after a long delay, it refused to send the message. So I tried again, this time giving it my new email password. The sending then worked. I assumed all was now OK.

But, as a final test, I exited Thunderbird, and then restarted. It again came up OK with my emails shown. Then I again tried sending a test message to myself. But it again asked for my sending password! Thinking this might be a scam, I put in a password of "bullshit". Then I received the following popup message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Polite people say HELO first. Please verify that your email address is correct in your account settings and try again.

What!!! It sure seems like someone (at Thunderbird?) is in the loop grabbing my password before encoding it for storage. A similar thing happened in the past, where I think my account was hacked. So, was this a hacking attempt, and if so, was it from Thunderbird software or my Comcast ISP?
