Thunderbird Community Forum

When I have Thunderbird desktop running but I am focused in another application, I receive a popup notification when a new email is received. In the popup, there is an X to make the notification disappear, but it would be very handy if there was also a trash can icon where, if you clicked on it, the message would be deleted from your inbox without having to go back to the TB app. I didn't see any such options in TB settings, and I have searched the forum to no avail. Is this possible? Thank you.

BlueHost has confirmed that our email (joe@wrigleyranch.com) and/or IP have not been blocked or blacklisted. We tested this together using the BlueHost WebMail app directly and can send and receive emails without an issue. We then tried again to send through Thunderbird. This is the exact and complete error message we received as we attempted to send a test message:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

 barbarawidener@gmail.com
   host eig-east.smtp.a.cloudfilter.net [18.215.58.191]
   SMTP error from remote mail server after end of data:
   550 Connection Rejected - see http://www.spamhaus.org/query/ip/162.241.225.213 AUP#BL

Reporting-MTA: dns; box5293.bluehost.com

This did not occur until the latest update by Thunderbird/Mozilla on Jan 14, 2026 at 7:35pm, MST. It is ONLY Thunderbird that is refusing to send messages, returning this SMTP error message. BlueHost contends that since we are not blacklisted anywhere that this must be an error generated somehow by Thunderbird as we can send email through BlueHost web mail without an issue or rejection. Spamhaus.org also confirms that we are not blacklisted nor restricted. We are only affected when trying to use Thunderbird that we have been using for well over 5 years without any type of problem whatsoever... ever.

We are, however, getting a very odd message from you as we reset our password when we had trouble using our stored password:

We received a request for a password change on your Mozilla account from: Chrome on Mac OS X 10.15.7 Phoenix, AZ, United States (estimated) Sunday, Jan 18, 2026 3:04:13 PM (MST)

WE ARE ON MAC OS X VENTURA 13.7.8. AND THE BROWSER WE ARE USING IS "BRAVE," NOT CHROME. Does this indicate or imply anything that may be wrong??? We are North of Phoenix in Flagstaff, AZ. So, this seems correct as an estimated location (150 miles North).

We need your help!!

Hi, I use thunderbird 140.6.0 esr for Linux (Debian 12 with KDE 5). After opening Thunderbird, I am asked for the password to retrieve mail. If I make a mistake when typing it in, I have no chance to correct the password and have to restart TB. There is a correction window for the SENT password.

We have not been blacklisted at Spamhaus.com. Yet, Thunderbird ONLY is blocking of email sent via its SMTP. IP being blocked according to Spamhaus is 162.xxx.xxx.xxx But Spamhaus shows that neither this IP nor my email, [edited] @wrigleyranch.com is being blocked or blacklisted. We are able to send email thru our email client at BlueHost. So, it is definite that we are NOT BLACKLISTED. The last update (automatic) by Thunderbird was January 14, 2026. I'm am suspecting that this update has caused this error. That's why I'm writing you. Can I revert to the prior Thunderbird update to test this theory? I cannot see how to do that. I need help!!! Receiving email is unaffected by this malfunction.

Thank you, Joe Amadeo [edited from community support forum] landline, no texts [edited] @wrigleyranch.com

On my PC Thunderbirds sending/receiving mail says the mail server refused my connection. My laptop works fine. I have duplicated my laptops in/out specifications onto the PC but still nothing works. Spectrum says everything on their end is fine but can't vouch for roadrunner who is the rr in my mail address of ca.rr.com. All this started about 4 days ago. Any ideas on what to try next? Thanks.

I have created several address books in Thunderbird for my contacts. How can I add all the names in a particular address book to one of the fields such as Bcc without having to add them individually?

Thanks.

I am using version 147.0 (64-bit).

I just started having a issue where it will be for example noon , and I just get a email , that is not on top but down the list and it says 9am , or similar times where it is 1 or more hours later from the time on the email , but it just showed up , but its down on the list of recent emails , so for example I check emails and a few come in or I get a notice that I have a new email

I have Thunderbird minimized in the taskbar , I never close it , and it will show a email from a few hours ago that just came in , but its below emails that I have already read that were after that time , so basically its like some emails just randomly appear that didn't get delivered when they were supposed to along with the others at that time , this is not a 1 time thing , this has happend several times over the last few days

I can't find any Setting that allows me to choose Newest Emails on Top , or to check the Time to see if it thinks its a different time of day than it is when delivering , or to bring in emails in order of delivery time , newest first and so on , so if a email has a Delivery time of 9:38 am I actually recieve it at 9:38 am , for example I got a email showing the time at 12:48 PM as delivered (10 minutes ago , but I just got the email now at 12:58 am) , then I got one time stamped at 11:15am , and 11:13 am , and at 9:38 am , , the 9:38 am email came AFTER I got the 11:15 email by about 30 minutes , and the one I just now got (it was 12:58pm when I got it , but it shows a time of 12:48 pm so 10 minutes difference from the time it shows delivered to the time I actually got it) , this is while my email is open and I am looking at emails ..... Email Version .. 147.0 ..

Any Ideas ??? .... Thanks .... Jim

The New Line (Enter) key always double spaces, which is intended for paragraph text. But for tabular text, this makes unnecessary white space. What key combination generates only a SINGLE new line character rather than TWO of them?

Example: Donor: xxxxx Email: xxxxx Phone: xxxxx Billing Address: xxxxx Bank: xxxxx; Account ending in xxxx

This screen defaults to single spacing; why doesn't Thunderbird allow it?

I've read this is a common issue but hoping maybe things have changed? Trying to make a filter that says move to the junk folder email where subject starts [SPAM] (the hosting service adds that) UNLESS the address is in an address book, BUT I also need to accept everything from numerous domains. I see work arounds "if the address ends in @somedomain.com" but then I'd have to do that for every domain I want to receive from. Any email from any address where I have put *@domain.com in my address book should be let through. But I know TB doesn't accept wild cards in the address book. There MUST be some way around this? Thanks.

I changed settings to no threading, but it continues to show the thread column in all the folders and do threading unless I manually remove the threading column from each folder - very time consuming. How do I get rid of the threading column globally?

good day....ii hope someone can help. the other day i was accessing my yahoo account spam folder and by accident, i deleted the spam folder instead of emptying it. the spam folder is now sitting in the trash and i'm unable to remove it from there. when i log into my actual yahoo account, the spam folder is where it's supposed to be and not in the trash. i tried removing the yahoo account from thunderbird and reinstalling it in hopes that it would rectify the problem, but it hasn't. does anyone have a solution?? i would greatly appreciate any help you can offer. thank you for your time...mike s

What font can used in Thunderbird that will display a capital I with top and bottom bars? Otherwise it's impossible to determine whether the letter is an capital i or the letter L.

Hallo,

ich möchte ein web.de-Mail-Konto in Thunderbird verknüpfen. Obwohl alle Eingaben und das Mail-Passwort richtig sind, kommt immer die Meldung: "Fehler bei der Authentifizierung. Anmeldung auf dem Server fehlgeschlagen. ...",

I used to be able to send an email or forward an email by clicking on "forward" and my address book would show up at the left side of the screen and I could click on the names I wanted to send or forward the note and it would add them to the "send to" of my email so I could send it to multiple people. For some reason that has now stopped and I can only send to one person at a time which is very cumbersome and time consuming. Does anyone know how to solve this problem? I hope I'm describing it right.

Thunderbird downloads from Gmail (a POP server) spam folder. It should only download from the "Inbox", isn't this correct? Gmail is not IMAP, which would dl all folders? Downloaded phishing and spam emails which come from the Gmail spam folder always have an incorrect time stamp.
