Thunderbird Support Forum

Greetings: Here is an error message that is now so common that I can no longer send email to any account. Also, I have not been able to send email to any gmail account for last year or two. Please help. Error Message:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: <MattMcKeegan_PLS@proton.me>... Relaying denied: You must check for new mail before sending mail.. Please check the message recipient "MattMcKeegan_PLS@proton.me" and try again."

Thanks. Matt.

I've been reorganizing my folders, and while working on this, I will occasionally find that I can no longer create a new folder or rename an existing one, or, somewhat worse, when I rename a folder, it will disappear, along with the messages that were in it. The messages that were in the missing folder don't show up in a search, and aren't in trash.

If I close Tbird and quickfilters, and sometimes also restart the computer, the functions again work as they should (but the missing folders do not reappear). Rebuilding the parent folder doesn't recover the missing subfolder. The problem can happen when Tbird is the only open application.

Any idea what can cause this? Or where the missing emails might be?

Thanks Kent

First, I am supporting a family member, who has TB configured on two separate machines. Configuring for Comcast IMAP+SMTP, in the usual manner; nothing esoteric about that, all very routine.

Machine A seems to be working okay, no errors. TB up to date on this machine, connected over an ethernet wire, if that makes any difference.

Machine B, getting spam prompted over IMAP 1014 errors. No other information is provided than 1014.

I have tried dropping the account configuration hundred percent, restarting TB, re-adding the account configuration, to no avail. Still spam 1014 errors.

I did happen to notice TB needed an update, so I did that as well. Still 1014 errors.

I have also tried dropping that email saved password from the saved passwords, and responding to the subsequent re-enter password prompt. Also to no avail.

What if anything might have changed, and how can we contend with this? What is so corrupt, do we need to be mucking around in any AppData files, roaming files, etc?

We are not the only ones, apparently, to have bumped into this issue. Not sure if this is also Comcast specific, since a recent TB and/or IMAP specification change, i.e. maybe we try with a gmail account, for instance.

Wondering also, is it IMAP and/or Comcast somehow tieing Machine A to the IMAP and not releasing that association? Knowing a little bit about IMAP in this regard. And/or somehow now prohibiting Machine B+ from establishing a connection?

Since starting my Win 10 Pro computer today, Thunderbird 115.4.2 (64-bit) has been "dead in the water". When it's launched, it posts the customary "Downloading Message 1 of [N]" status report, but then hangs right there, takes 3 or 4 minutes even to (re-)populate the tabs and panes that had been open, doesn't get past the alleged first new msg even in 15 or 20 minutes. When it does populate the Inbox pane, it shows no messages newer than last night just before shutdown. Very sluggish response to cursor, too: for ex. 30 seconds from clicking on a msg title in the Inbox pane to displaying that msg, even longer to bring up Help/About (with "Not Responding" shown in its title bar.)

  I get my mail through gmail's IMAP server but prefer to use Tbird's interface . Thinking there might be something evil about the first msg that was waiting to be downloaded, I used gmail's web interface to review everything new since last night, deleted several msgs that had attachments, then started Tbird again.  No change.  Can't even get Tbird into the "Work offline" state because it attempts download-of-new-msgs immediately after being started.
  The only consistently effective way I have found to STOP the hung Tbird is through (Classic) Task Manager's "Processes" list, which usually shows five or six "thunderbird.exe" instances.  After selecting whichever has the largest memory allocation I click on "End Process."
  This all "feels like" a bollixed internal state.  Does Tbird store internal-state information in its own file, or is it buried in the Registry?   If I attempt restoration from a backup, which files are needed; or is that unwise?
 I see there is a mid-April update available to 115.10; would installing it reset current messed-up internal state, or will that already messy situation prevent the update?   Is there any risk of losing my Inbox, Sent, etc contents?

Thanks!!!

Wanted to sign in to forum.k9mail.app so I could stop asking K-9 Mail questions here. Filled out the "application," but have never received confirmation email back from forum.k9mail.app to allow me to sign in. Re-requested confirmation email 3 times; no reply. Can someone help me?

What address do I need to add to my address book so that replies from this forum don't go right into SPAM/JUNK folders?

I have thunderbird 115.11.0 (64-bit) on Linux After hitting the test button, I get this error message:

Component returned failure codeL 0x80004005 (NS_ERROR_FAILURE) [nsIFile.createUnique]

Password OK

What does this mean? How do I fix it?

Bonjour, les courriers envoyés par l'un de mes correspondants avec son adresse Axxxx, n'arrivent pas dans deux de mes adresses mails. Dans la troisième, SFR, ils vont directement en quarantaine. Si ce correspondant utilise une autre de ses adresses mails, Bxxxx, le courrier arrive normalement. Je rectifie chaque fois le statut de ce correspondant, je le déclare comme acceptable, je le déplace de la quarantaine vers le courrier entrant sans succès même si je ferme TB et le ré-ouvre ensuite. Où chercher? J'ai regardé les occurrences ouvertes par la recherche à partir de "quarantaine" et je n'y vois pas de solution. Win7, TB à jour. Merci

hi

I made a mistake to uninstall thunderbird  due to a few issues . now the new version is refused to be installed 

my version was 15-321OM ,,cpu thank you regards

Hi, after reading the documentation i read that that automatic filters only apply to inbox and archive.

Hi have the following issue : sometimes i have fake positive for spam but these message are flooded in real spam. Some job offers answer can be in such folders.

Therefore i created a blacklist filter for spam so as to ease my spam review.

Unfortunately i i have to manually run them. Long time ago i had to go to message filters and then select the folder. Now i can easily click on the "Run filters on folder", option/alt T+R is also nice i am really grateful for that.

- Would it be possible to allow automatic run of filter on some specific/explicit directories ? (after thinking my question twice i understood that checking for circular rules can be very complicated, maybe a warning if a message is to be processes twice by the same rule) - Maybe add a one click shortcut ? button ? - An easy export/sync from/to imapfilter ?

Besr regards.

My Thunderbird cache is using a gigabyte of disk space. I'd like to clear it, but it's not clear to me if I would be wiping out stored messages when I do that.

I like to download my emails to my computer (and keep copies on the server, too). I thought that was what I was doing, since I can view my emails when offline, but maybe I'm just accessing the cached copies?

Will I lose my old emails if I clear the cache?

Good day Mozilla vols! Has anyone else heard of, or developed an issue recently where TB will not delete multiple emails when selected? Previously, when I selected multiple emails for deletion and clicked "delete selected messages", TB would hang for a bit (while processing), but then all my selected messages would be deleted from both TB and my mail provider.

With timing conspicuously aligning to the 115.10.2 update, the multiple email delete functionality has broken. Now, when I highlight multiple emails to delete, instead of deleting them, TB marks them all as read, and only deletes a single email (the oldest email in the group I selected).

I saw one other question about this, but it was marked "archived" without an answer. Any thoughts/suggestions would be greatly appreciated.

Mail provider: gmail OS: Win 11 Security: Windows Security (old Windows Defender) TB client (now) 115.10.2 Troubleshooting mode (with controls reset and add-ons disabled) did not resolve the problem

Login to server imap.gmail.com with username spinneyhill15@gmail.com failed. I have tried for 2 days but am getting nowhere. Please help.

This is what the message says. It got hung up after the DONATE message posted. i donated, but it didn't free it up.

"Unable to open the folder Inbox on robert@perless.com because it is in use by some other operation. Please wait for that operation to finish and then select the folder again."

Apple says it is a TB problem, not an Apple problem. Somebody please help.

I am running this computer for my late husband who left us in September after he fell off a 25' ladder at the age of 85. It still has all the information from his art. He was a sculptor who made large kinetic pieces.

On opening Thunderbird every morning, ALL my folders are expanded and I have a lot of folders! I have A-Z and then many many subfolders within each folder. It's extremely frustrating as I have to collapse them all every single time. Is there a way of never having this happen again?

Today (for example) I saw a message 'Downloading message n of 182 messages' (n increasing with every message downloaded but the message disappearing well before 182). According to the activity manager and my own reckoning 72 were downloaded. An incorrect number of messages to be downloaded has been shown every day since 26 April 2024 although my previous download was on 20 April when the number that day (and on previous days going back many years) was correct. I have included messages in the Junk folder in my reckoning. The account is POP mail server and my Thunderbird version is 115.10.1 (64 bit). Not life threatening but can I fix this or can a recent change be corrected as I found the number being downloaded figure useful when it was correct.

I keep getting the message "Sending of password for user kcmsansiro did not succeed. Mail server pop3.iinet.net.au responded: [SYS/TEMP] Account is temporarily unavailable." and "Sending of password for user kcmsansiro did not succeed. Mail server pop3.iinet.net.au responded: Disconnected for inactivity." and "Login to server pop3.iinet.net.au with username kcmsansiro failed" on all 3 accounts (kcmsansiro, phildemaria and philrossi)

I can still receive messages on phildemaria but cant send without getting these messages

Recently been migrated to the message co

Thanks for any advice you can offer

I am currently in the process of integrating the Thunderbird policies and about:config settings into a Nix module for NixOS.

It would be nice to be able to easily correlate Thunderbird versions to the matching documentation version. This could be done by using tags on the documentation repository.

Would it be something the Thunderbird team could be considering to add to their workflow?
