Thunderbird Community Forum

A week or two ago I started having two problems with Thunderbird, but only with some emails related to my clients. Here is a description of each problem (in case the problems are related):

Doubled incoming emails

Emails received at my address david@nsrusa.org are being received and displayed twice. I have set both my email domain servers to delete messages from the server, which is the top advice always given for this problem. The advice doesn't work for me.

Outgoing message failure

Some messages I send using Reply (perhaps the doubled messages) are getting "stuck" in my email server, which keeps sending me updates on this failure. Here is the start of a typical failure message:

This message was created automatically by mail delivery software. A message that you sent has not yet been delivered to one or more of its recipients after more than 48 hours on the queue on server.springtimesoftware.com.

The message identifier is: 1uQFjK-00GA1j-05 The date of the message is: Fri, 13 Jun 2025 21:30:45 -0400 The subject of the message is: Re: Your recent postings

The addresses to which the message has not yet been delivered are:

 ***@bol.com.br
   host mx3.bol.com.br [200.147.41.201]
   Delay reason: SMTP error from remote mail server after RCPT TO:<***@bol.com.br>:
   450 4.7.25 Client host rejected: cannot find your hostname, [69.48.183.241]
 ***@gereconsult.com
   Delay reason: H=mx-vip-01.kinghost.net [191.6.216.38]:
   SMTP error from remote mail server after RCPT TO:<silviomartins@gereconsult.com>:
   450 4.7.25 Client host reje

My environment: Mailservers are mail.nsrusa.org and mail.springtimesoftware.com, both at IP address 69.48.183.241, Windows 11 Home 64, Thunderbird 128.8.1esr 32 (I have just updated to 128.11.1esr), hp laptop.

I have a rule that moves email messages from backups to a 'Backup' folder. I also have another rule that moves emails address to myself to 'My Mail'.

When I start TB 128.11.1esr in the morning my 'Backup' and 'My Mail' folders show new email counts. When I click on 'My Mail' the number on it decreases and 'Backup' increases. This happens with other rules on other folders.

So, my question is this behavior caused my 'Message Filters' being triggered when I click a folder or potentially a latent refresh of the folders new email counts.

Thanks

Hello Team, I installed thunderbird yesterday and so far its looking promising and actually I started to like it. But when on my first email draft I tried to use search and replace (Ctrl + h), I was not getting any highlighted letter on pressing 'Find Next'. When I press on 'Replace' still 'Find Next' button is highlighted and also nothing seems to be replaced. It is only when I close the Find and Replace window I see my changes. I am attaching picture for your reference. If this is not standard feature then please provide support to fix this issue.

My password is not being accepted, so I'm not getting my mail. For quite awhile my password would sometimes not be accepted for sending email, but now it's for everything. How can I fix this?

Just installed the latest 139 version on two computers, the system tray icon for unread messages appears in Windows 10, but not in Windows 11, and it isn't just 'hidden' as I have many icons hidden and just a few visible and have already checked that. Is the icon no longer part of the program?

how can I copy my encrypted gmail passwords so that I can use it to sign into my Thunderbird gmail accounts to send and receive email using the Thunderbird app? Thunderbird has now decided that the passwords I have used for years to sign into my two gmail accounts are not valid. Think Tbird wants the encrypted version of each password, but don't know how to figure out what that is. Not listed in the encrypted version in my Tbird saved passwords.My other accounts continue to work well with Thunderbird. I havve many folders that I do NOT want to lose i I have to delete and then reestablish those two accounts, but the copy/move to another folder on my laptop will not work. Nothing happens when I try to follow the instructions. Please help!!

I use Thunderbird on my desktop and laptop, both Windows 7, with 3 Gmail accounts. Recently I started having problems with one account on the laptop but not on the desktop. Settings for all 3 accounts are/were identical. I deleted the one account and tried to add it again: with following error message:

     "Unable to log in at server. Probably wrong configuration, usrname or password.

I then added account manually without a password. I cannot access the email account and dont get an option to enter password and error is:

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

Yes SMTP setting is correct

This message also pops up:

    "Authentication failure while connecting to server imap.gmail.com"

I have no problem accessing all 3 email accounts on my desktop or phone either Please assist

Re: 128.11.1 esr (32-bit) Curiously, without settings having been changed and only since last 2-3 updates, my unified inbox listing comcast.net and netscape.net mail will not show the netscape.net incoming unless it is actually READ in its separate inbox. Periodically, duplicate messages do now appear, but without the new, un-opened netscape mail. This duplication is corrected by exiting the app then re-starting it, but the new mails still are not listed in the combined unified format, nor are they, for that matter, in the ALL format. Wassup wit dat?

hello I left account A (Google) and I am mainly using account B (Google) now. However, when I search for the mail of account A, it only shows the result, but after clicking it, it shows that there is no mail. How can I recover it? This is because the most important mail is in account A. PLEASE HELP ME....

Hello!

We use some filters in thunderbird to manage messages redirection to other mail-boxes. When message body contains any image, it disappears after redirection via filter rule.

When you forward same message to the same person by hands - works great, nothing is missing.

Can you help with any suggests / advises for thunderbird client config to fix this?

We use Thunderbird 115.5.0 (64-bit).

Thank you.

I know this question has been asked before, but haven't been able to resolve the issue - I have in my Trash folder, the Spam and Draft folders there, no idea how they got there. I use multiple computers and have the same issue on all. I am running Thunderbird 128.11.1esr (64 bit) on my desktop, which is Linux Mint.

If there are any suggestions on how to move the folders back to their original location, would be good, unless I have to now live with it.

Thanks, V1King

I'm hoping to find some syntax documentation and/or information on how to do more complex searching within Thunderbird.

I've seen references to some basic multipart searching capabilities. (ie. placing scott "tuesday night" in the search field would result in a list of emails containing both of those criteria.)

But I'm looking for even more such as placing scott "tuesday night" folder:inbox, which would allow me to narrow down that search to JUST the inbox, not any and all folders below it.

Thanks in advance,

Chris

On my new laptop (Acer Aspire) I set up my gmail account without a problem, but T-bird will not set up my business account (on my domain, hosted by midphase/stackmail). I used all the settings from my t-bird account on my old laptop, but nothing I try works. I get a yellow box with the message "Unable to log in at server. Probably wrong configuration, username or password". I also tried lettting Thunderbird find the settings; they didn't work either.

What next?

I was moving stored emails between folders. After many moves, when moving a group, the move failed with message "TOO BIG" APPEND  ??. Since then, I have been unable to move or copy even single emails. How can this be cleared?

The employee who set up Thunderbird for us, has moved on to a different line of work & no longer with us. Her name is on all the emails and templates. How do I change these and how do I secure our emails from her use now that she moved on?

I edited & saved each and every Template earlier today. Then, when I went to check my work, nothing had changed.

Help me please.....and talk to me like I'm just beginning computers, because...I am.
