Not sure which "topic" best describes my question, so . . . .

OS: Windows 11 Thunderbird 140.1.0esr

I have been using T-bird for several years, and have made to changes to configuration in recent memory. Beginning today, when I try to send an email through my Comcast account, it fails with the following message:

“An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-h2p-555031.sys.comcast.net resomta-h2p-555031.sys.comcast.net EXMTP server not available.”

The outgoing SMTP server is configured as follows: Outgoing server: smtp.comcast.net Port: 465 Security: SSL/TLS

For comparison, sending email from my Android phone, using the Gmail client with the same server specs, also fails, thought it gives no information.

For more comparison, I configured Outlook to test with it, and it was able to send successfully. I noticed in setting it up that it used the same server name, but with port 587. Armed with that information, I changed the port setting in T-bird to 587. With that change, the send still failed but with a different error:

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.comcast.net was lost in the middle of the transaction. Try again.

Any help is appreciated.

When I create a task, I set reminders for say 5 minutes before. But they never 'fire'. Reminders for calendar events work and I know Thunderbird treats Events and Tasks somewhat the same, but I don't know how to get them to fire off. Thanks

I have a message filter that sends email to the deleted folder. I have a message from sender = reverb.com that is getting placed into delete folder. Reviewing the filter log file, it shows that particular filter is the filter moving the message to the deleted folder. I painstakingly go through each entry in the filter and "reverb.com" is nowhere to be found.

This is weird.

Any assistance troubleshooting this would be appreciated. I donate to Thunderbird.

Thank you.

I hope someone can help because I'm ready to dump Thunderbird.

WHAT I WANT: When I receive bulk or junk, I don't want them stored, I want them gone immediately. Just looked at the bulk folder and there were over 1,000 emails. It took four repeats to get rid of them all. Add to this the fact that deleted bulk goes to Trash and I have to do it again. Just empty the damned folders. Why wait even a day???

WHAT I'M GETTING: Everything hangs around and I must manually delete the garbage.

When my computer was repaired, Windows was reinstalled but I lost various programs, including Thunderbird. I had to reinstall it. I assume my data--my email database--was not erased, but I don't know how to access it. The online help menus are not helping. How do I connect the program with my existing profile, which I assume is still on the computer somewhere?

After the recent update to 140.1.0esr Lightning calendar reminders do not come up correctly (W11 if it makes any difference)

Previously reminders worked as they should, I have several daily, some weekly, fortnightly and as required, only the odd one comes up and one or two will come up but then disappear without my intervention

I have tried all the various settings to no avail

Someone in another thread suggested their old email address needed to be changed in Calendar properties, but I cannot find Calendar properties anywhere

I used to use Remindafox which worked better than Lightning but had to use Lightning when it was discontinued

Is there a fix for this as its totally unreliable at present

I just updated to version 140.0 and now my subfolders are out of order. Is there a fix for this, short of fixing it manually? I miss how they were automatically alphabetized. That went away when manual reordering was implemented. I can't grab a bunch at the same time and move them, since the order is so messed up.

I am guessing that my inbox messages disappearing had something to do with a Thunderbird update.

Pay attention mainly to the lines that mention "key".

   Access your AT&T Mail using your favorite email apps
   Synchronize other account info, such as your calendar and contacts, to your email app.

Create a secure mail key

It’s easy to create a secure mail key from your mobile device, tablet, or computer. Have your User ID and password ready to sign in to myAT&T.

   Go to your myAT&T Profile. Sign in, if asked.
   Scroll to My linked accounts, select the email account that needs a secure mail key.
   Scroll to Secure mail key, select Manage secure mail key.
   Choose the email address that you’d like to use, if you have more than one.
   Select Add secure mail key. Enter a nickname for the secure mail key to make it easy to recognize.
   Choose Create secure mail key.
   Select Copy secure mail key to clipboard. Make a note of your secure mail key for further updates.
       For security purposes, the secure mail key only displays until you select OK.
       If you lose or forget the secure mail key, you can always create new secure mail keys.
   Select OK.
   Go to your preferred email app, replace the existing password with your secure mail key. For an IMAP account, delete the existing password for both the IMAP and SMTP servers. Replace them with your secure mail key.

Good to know: Each device you use to access your email will have its own secure mail key. Additional secure mail key notes

Access your AT&T email account without an OAuth mail app or secure mail key

You can always read and manage your email through a Web browser at currently.com.

A secure mail key won’t affect your AT&T email password

You’ll still use the same password for your AT&T Mail account in OAuth-compatible apps, myAT&T, and other AT&T products like currently.com and webmail. When you change your AT&T email password, you won’t need to get a new secure mail key.

Keep your secure mail key as long as you like

Secure mail keys never expire.

Create a new secure mail key for a blocked or locked account

For safety reasons, we delete secure mail keys whenever we have to lock or block your account. If that happens, you’ll have to create a new secure mail key for each AT&T Mail account.

Give your secure mail key a nickname

Create a nickname to identify your secure mail key, especially if you have more than one. It’s much easier to recognize a nickname, like Ari’s email or Kelly’s email, than the 16 random characters you entered when setting up your email. Last updated: March 12, 2025

When I went through this process, it showed a key from 2024.

I merely deleted it and from the same page created a new key. After that 500 emails from the last week started downloaded to my inbox.

Happy again.

Hi, I'm trying to save several msgs that have .jpg files within them (not attached) I save one by opening it, pressing M + H + Enter + A (to Save).

Can I do this w/out doing it for each msg?

Lots of work now.

Thanks.

I'm an IT consultant trying to help out a poor client of mine who suddenly has been getting tons of nasty profane spam. Her email address must have gotten on somebody's bad list because this just started happening after years of relatively little spam. It comes in huge bursts.

We had turned to Thunderbird because it was supposed to be good at isolating spam. But no matter what I do, it won't move ANY spam to the Junk or Bulk folders. Yahoo uses Bulk so I told Thunderbird to use that folder. I also told it to use SpamAssassin. It is EXCELLENT at marking all these emails with the little symbol for SpamAssassin, but it doesn't automatically move them. And there's no rule system that can move them. I've tried it at the local level, account level, every possible setting, and the old ones stay in the Inbox and the new ones go directly to the Inbox. I've even turned off antivirus to see if that was interferring.

I really don't want to give up Thunderbird, but this isn't working and it's the reason we came to Thunderbird. Can anyone shed some light on this?

New update 140.1.0esr broke connection to my AOL verizon email (##@verizon.net) Apparently AOL mail will not accept the password or something. Have tried lots of things (including 2-12 hour chat with AOL mail "tech support"). Exactly same thing on my wife's desktop install. I considered trying to roll back to previous release - but I had both set to not install updated without asking permission. So I assume if it roll it back it's just going to update again without asking for permission. HELP! I've spent at least 6 hours on this already.

Please help! I have tried all the top level fixes, checking permissions, restarting, all the settings, advanced and otherwise. Troubleshoot mode. I have not reinstalled the instructions file - forget its name... is that necessary/useful? Or is there a way to find code that is overwriting improperly. It's not just for what I write now, wherein an attempt to, say, make a specific word appear blue fails. But what is stored and read through thunderbird also loses its color-switch.

Thanks.

TBird maul ott corrupted. There are a qty of folders in the mail folder with similarr names. Can someone please tell what folders s/b there? Also have 5 TBird Local plus subfolders in my main mallboxo - how do I remove those?

Have tried and uninstalling to get a clean install - it doesn't work!

Sincerely HLA

Emails from certain senders (big companies like Amazon, Twitter and YouTube), after having been received normally for some time, suddenly stop arriving. They are not in a junk folder and nothing I have done has been able to get anything into a junk folder.

I also receive emails on my phone, and the problem messages ARE in a junk folder there. (I only just realised this.)

The problem seems to be that Thunderbird sees some messages as junk but instead of putting them in a junk folder it disappears them completely. From the evidence on my phone, nearly everything being flagged as junk is real email, things I want. If I could simply tell Thunderbird to receive everything it would be fine, but I don't know how to get these emails to download.

Looking at what is in my phone I see a load of important stuff that I really need, in my junk folder there. It's not anywhere in Thunderbird. How can I get this to download?

Good evening! After updating the update to the latest version of Thunderbird, the address book stopped working. Reinstalling the program did not help, rolling back to the previous version - swears that changes in the profile do not allow the application to run. Deleting abook.sqlite, abook.sqlite-wal, and abook.sqlite-shm did not solve the problem. After deleting all the files, logging into the program and trying to create a new address book, nothing happens, only these three new files are created in the profile. The address book is local

I have been using Thunderbird email for years, and when I bought a new computer, everything transferred over perfectly. Now, I've suddenly lost all incoming and outgoing use on my computer, but still receiving (not able to send) on my android phone. All my settings on the computer are now messed up and I don't know how to fix them. I had all the settings saved on my backup external hard drive, but that has now gone bad and I can't access any photos where the settings were kept.

Good morning -PLEASE help - I had numerous e-mails in my inbox that went away - when I opened this am only yesterday's were in there ......I am sooooooooo IT incompetent

Thank you in advance - some very important stuff was in there.....

As per subject.

The first search will generally work fine and I can group email and move then to a relevant folder by dragging or using the Move facility in the Search pane.

If I should perform another search, I cannot move even a single email by dragging or using the Move facility.

Even closing and reopening search does not help. I will have to close down Thunderbird and start all over.

Any ideas of what's I'm doing wrong?
