Title. Thunderbird is a really cool client but it's pretty slow. I blame that on the thousands upon thousands of emails that my hotmail and gmail each hold. I don't necessarily want to delete these emails, but I have seldom a reason to have any email older than 2 months in my thunderbird client slowing and crashing the program whenever I want to combine inboxes.

To this end I went to "Synchronization & Storage" and told it to "Synchronize the most recent 2 months" but it didn't delete the huge cluster of older emails. The next option is to tell TB to delete these emails in the same menu but as I understand it that would also delete them in the server, which I don't want to do for posteriority.

What do I do?

This is the message I get when trying to send emails: "Sending of the message failed. An error occurred while sending mail. The mail server responded: pgbentley101@gmail.com recipient rejected. Please check the message recipient "pgbentley101@gmail.com" and try again."

Email that I am sending from Thunderbird is being rejected for no apparent reason by the recipient server. This is not due to an ISP or sending server security issue since, when I send exactly the same email from my ISP email web page (not Thunderbird) the email is received properly and accepted without error. So, the problem is most definitely with Thunderbird. The following is the header text from one of the rejection replies.

Do not reply that his is an issue with my ISP. It is not. It is purely a Thunderbird issue. Thanks for your time.

Was just updated to version 115.5.1, and I had held off posting this question until after the update, hoping the issue might be resolved... but it's as bad as ever.

Tbird abruptly became very slow to delete/display messages; not with the last update, but a couple of updates previously. I have been in the habit of working my way up the list from the oldest to the newest, and as I hit "delete" and "up arrow" to view the next email, it's a slow, laggy process. Both emails remain highlighted for a second or two, the old email continues to display, then the deleted email drops out, and shortly the new one displays, the whole process taking a bit over two seconds... to move from one email to the next, a process that used to be nearly instantaneous. No idea exactly when that changed, but it seems to be a process that's getting worse with time.

Any ideas on what I might be able to do to get my original level of performance back? For what it's worth, this is a new machine, insanely fast compared to my older one, and Tbird is the only app where I'm encountering this kind of slowness issue. Everything else is astonishingly faster by comparison... but Tbird remains laggy and slow and I've no idea where to start looking for reasons for this. Don't even know what kind of information to post here that might be useful in diagnosing the issue - - tell me what's needed and I'll do my best to get it. Thanks in advance! I *really* don't want to change email clients after all this time!

Jeg kan ikke sende mails i Thunderbird, men jeg kan godt modtage mails, det har varet i ca 1 måned. Problemet har vist sig flere gange i de senere år, og så har I rettet det. Er der mulighed for at tale med en tekniker? Så ring venligst på 21135659. Venlig hilsen Minna

I have just switched to Thunderbird from Gmail. Have tried several times to send bulk emails but always get this message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: We have detected an unusual amount of suspicious mail originating from this address. Please try again later.. Please check the message and try again.

I have a need to send emails frequently to more than one address and this is going to be most inconvenient if it can't be fixed. Is there a setting somewhere?

Thank you.

Hello, Thunderbird user daily for years. Lately every time I open Thunderbird it starts downloading a random number of emails, usually in the thousands. this makes the app extremely slow and laggy until it finishes. I use it daily, on avg getting 20-30 emails. I don't understand why its downloading emails form months to years ago.

Back in 2016, via GoDaddy I set up a personal domain. As part of the package, they offered to host two email addresses using that domain. I set up both in Thunderbird.

In June 2022 GoDaddy asked that all such accounts be switched to Microsoft Exchange, which I did with one of the two.

Very recently, perhaps with the recent Thunderbird upgrade, that account--and its sub-folders--have disappeared from Thunderbird. I need to restore them.

Thanks for the help!

Granted, I have massive boxes...but in my Sent folder, I checked a mail sent just this morning and wanted to right click it to 'edit as a new message'...however, when it opens, the content is related to a different email and the sendto email is also from a different email. Is there a way to clean up something like this? I shut down TB and waited and reopened and the issue stays the same.

The Not Responding stuff, plus this, has me looking for an alternative.

When I use a html signature with graphics, the recipients who can not receive Html, do ot receive the grafics, obviously, but also not any other attachment like a PDF file. The same is sent but not received! in other words, our customer complain that we forgot the attachment, but we did not. If I resend without the signature, they receive the PDF file. If I reply with an attachment and have a previous signature with grafics in the feed, the attachement also disapears. The only solution is no grphics in the signature, but that is not a solution, just a quick fix. Thank you very much for your replies.

Hi, I've been having a lot of issues with the RSS feed handling on Thunderbird 115 on Fedora 39. It's been very unreliable with my collection of RSS feeds assembled in Thunderbird over the past ~15+ years. So I've been working on recreating my feeds account and after a few times it's been working more reliably with my 200+ RSS feeds. But I've noticed the behavior of the RSS feeds only updating every 100 minutes or so per the new default.

I did re-import my feeds after changing the account settings default of "Check for every new messages" to say every 10 minutes rather than every 100 minutes, but it didn't affect existing feeds or new feeds added after that point.

As a longtime Thunderbird fan it's been quite frustrating especially with long relying on the RSS feeds. Is there anyway to force-override how often all RSS feeds are updated? Or any guidance to where those individual settings are stored so I can find/replace the values all much more quickly than updating on a per-feed basis?

Thanks many, Michael

My thunderbird email is linked to my Virgin media email. Suddenly Thunderbird has stopped working, so cant send or receive messages. Any ideas - the virgin email is working fine.

115.4.2 macOS 13.6.1 Using Menu>Edit>Find>Search Messages, it appears to be impossible to change the width of one result column without changing the width of all columns.

I want to widen the Date column so that I can see the full month name, the date, and the year. I click on the bar at the right of the Date field header and drag it to the right. All columns to the left are widened. The Date column barely widens. I click the side of the window and widen it. All columns widen (not a problem). Date widens a bit. I try to widen it using the bar at the right of the field. Same trouble. I widen the window to full width of the screen. Same trouble. The names of months with shorter names show in full, but not, for example, 'November'. Still can't see date on some; can't see year or time on any. I move the window to the left so all columns are off the screen except Date, Total, and Location. I widen Data. Correspondents appears on the screen (I guess that all columns are being widened). I widen the window all the way to the right of the screen. Now Recipient and Correspondents show, very wide, mostly blank (when there is only one name); there is a very wide column to the left, all blank, the column name invisible off the screen to the left. I can now see most Data data, but, for example, 'November 11, 2023, at 10:2'. I push the window further to the left off the screen. I now see Correspondents (mostly blank to the right of a single name (the one I searched for), Date, Total, and Location; I see the date and time in full. I can't see any column to the left of Correspondents; in particular, can't see Subject. I move the window all the way to the right edge of the screen again. Now I can see the "blank column," Recipient, and Correspondents (mostly blank space), Date with all dates and times showing in full, Total always blank), and Location (short mailbox names, so all show in full.

Why was this design chosen by the project? What was wrong with the ability to change the width of any column without affecting the others? Why was the decision made to not have a scroll bar on the bottom?

Thanks in advance for responses from the team.

Cordially, Joaquin

There is not scroll bar at the bottom, so I can move the data in the window back and forth.

At 15:00 yesterday, my Thunderbird was updated (behind my back).

From that moment it could not communicate with my imap server and I cannot renew my account with the server.

I now have to use webmail.

Can I please go back to the immediate predecessor as that has worked well.
