I get this message everytime I try and send emails

I'm using Thunderbird 149.02 to make a local copy of all folders, messages and attachments on my yahoo mail account. I don't yet see an obvious way to issue a command to Thunderbird to accomplish this.

I'm using export.imap.mail.yahoo.com as the IMAP server as some of the folders have >10000 messages (none have >100000 messages, and there is no significant real-time email arriving to the account while I do this procedure.)

In settings/offline settings I have "automatically follow detected online state" and "download messages for offline use when going offline [yes].

In account settings/synchronization & storage I have Disk space: Synchronize all messages locally regardless of age"; "to recover disk space, old messages can be permanently deleted..." I have "Don't delete any messages" and "Always keep starred messages"

With these settings, I've tried (from the main menu) File -> Offline > Download/Sync now, then "Download and/or sync..." I have selected Mail Messages, and the Select button takes me to a table where I have selected the main account folder and all sub-folders.

With these settings, Thunderbird appears to go through some of the folders and downloads messages from, them, and after a while says there are no new messages (I don't have the specific text, but it ceases interacting with the server". If I repeat the Download/Sync now procedure, it appears to download more messages, will continue for a while, then stop in the same way.

When I compare the size of Thunderbird's local account folder, it appears to grow after each of these iterations, but is (after half dozen cycles through this) has only reached about 2/3 of the total stoage size reported by Yahoo. While I understand the storage mechanisms would differ significantly between yahoo and Thunderbird, I don't believe I've found a single sure-fire way to accomplish what I set out to do in the first place (which is get a complete copy, through IMAP, of all emails, folders and attachments.

What am I missing?

Thanks,

I have been using Thunderbird with two POP3 Hotmail accounts for some time and I am trying to set up a third account with exactly the same configuration. However, both the automatic and the manual configurations failed. The new account receives mail, but the outgoing smtp server config seems to have a problem. Sending messages times out or keeps prompting for a new password.

The Hotmail account has POP3 and IMAP enabled. Thunderbird is set to receive all cookies. I cleared history and cache after every attempt and also temporarily disabled the firewall.

Any suggestions about what the problem could be?

I get the messgae 'Unable to write email to the mailbox...make sure the file system allows you write priviledges and you have enough disk space.' When I looked at the errors Thunderbird recorded I found thei:

pop3.server1.2: Incorporate write FAILED! Component returned failure code: 0x8007000e (NS_ERROR_OUT_OF_MEMORY) [nsIPop3Sink.incorporateWrite] NS_ERROR_OUT_OF_MEMORY: Component returned failure code: 0x8007000e (NS_ERROR_OUT_OF_MEMORY) [nsIPop3Sink.incorporateWrite]

I recently had to restore my thunderbird app as I had issues with my laptop. I do not run Avast...I have tried the 'repair' option in folder properties in thunderbird. Nothing seems to help. I would appreciate any assistance you can give me. I have been using Thunderbird for....well it has been aloooong time and I have never had any issues with it previously. I am running WIn 11 Pro.

I have connected a Google Workspace (Gmail) account to Thunderbird, let's call it scott.harper@myorg.org. I am able to send, receive, and reply from this account as expected.

In my Google Workspace configuration, I have an alias address forwarded to my account, let's call it info@myorg.org. I receive messages addressed to "info" just fine. But when I send or reply to messages addressed to "info", I'm running into a problem.

In the Account Setting I opened Manage Identities, and added info@myorg.org as an alternate identity. I then edited the Private Data for that identity so that the "Reply from this identity when delivery headers match" option is checked, and set to match info@myorg.org. See attached image.

When I reply to an incoming message, the From field appears to be (sort of) correct... it shows from info@myorg.org, but next to it (in italics) is the primary account identity, scott.harper@myorg.org. See the other attached image. This is also the case when I compose a new message and select the info identity.

In both cases, when the message arrives at the destination inbox, it is from scott.harper@myorg.org instead of "info".

I'm assuming I don't have the matching rule, or some other setting configured correctly. Would appreciate any other tips/ideas.

Hi I have a hotmail account registered to my Thunderbird account, I receive mail. OK but it won't send mail comes up with error "unable to connect". Followed by:- (Should be a screenshot but it wont load?)

which says "Sending message failed The message could not be sent connection to server SMTP timed out."

This is a new occurrence not experienced before?

If I go to webmail it will send OK?

I started getting this message when I attempt to download my email to Thunderbird:

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I am using AOL with the address: rc.woolfenden@verizon.net on a Windows 11 platform with a 1TB solid state hard drive. I have never encountered this issue before.

Mail filters for custom headers like List-Unsubscribe, Authentication-Results or Received-SPF copying messages from IMAP accounts to Local Folders do not work on the Yahoo! IMAP account. For example:

filter1.jpg: name="_Inbox2: List-Unsubscribe <https" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox/_Inbox2" action="Stop execution" condition="OR (\"list-unsubscribe\",contains,<https)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

filter2.jpg: name="Spam: Authentication-Results dkim=unknown | Received-SPF fail | X-Antivirus-Status Infected" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Junk" action="Stop execution" condition="OR (\"authentication-results\",contains,dkim=unknown) OR (\"authentication-results\",contains,dkim=perm_fail) OR (\"authentication-results\",contains,dkim=none) OR (\"received-spf\",begins with,fail) OR (\"received-spf\",begins with,softfail) OR (\"received-spf\",begins with,none) OR (\"x-antivirus-status\",is,Infected)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

But filter3.jpg for Subject works well: name="Inbox" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox" condition="OR (subject,doesn't contain,t[k\6iq69pd+}'cr)" (copies all remaining messages from IMAP folders to Inbox on Local Folders)

(the snippets above are fragments of the msgFilterRules.dat file)

Filters1 and 2 work well on other IMAP accouns, like for example wp.pl. So this is about Yahoo or something is corrupted. My question is, what wrong is here ? And by the way - how to create filter copying all messages from IMAP to Local Folders ? Is better way then filter3 looking for random string in the subject or somewhere else ? Thank you.

Yahoo email simply stopped working on APril 5 mid- night. last message is 04/ at 1130pm. in my setting in the yahoo account it shows thunderbird as having access permissions. Thunderbird simply can't log into yahoo anymore or download the messages.

I have deleted permissions in yahoo, and Thunderbird's saved passwords . Created an app password in yahoo, logged in with that one-time password using thunderbird and it says it didn't recognize, then I typed my real yahoo account password thunderbird crashed. Thunderbird simply can't connect to yahoo mail anymore.

After zeroing out save passwords and removing third party from yahoo account. I signed in to yahoo from Thunderbird. Yahoo mail now shows Thunderbird has access.

YES I HAVE all the settings for POP and smtp correct. Nothing in yahoo changed for those settings since April 4th.

I need this account working again. Please tell me step by step directions on how to remedy this. Emails are backed up so if have to remove account and start over fine. but I want exact steps. I have been going around in circles. Thunderbird simply isn't accessing or connecting properly with yahoo mail through oath2.

Have an AT&T email account on 3 computers. Two of them running windows 10. One mqchine running windows 11. On the windows 11 machine, we set up a new email account and it doesn’t work. Sometimes you cannot send or receive. We delete that account and create a new one and sometimes it receives but does not send. It asks us to retry or enter a new password. We enter the password and still fails to authenticate. We tried setting it up as POP other times as SMTP. Still fails. Sometimes we get a yahoo pop up to help us set up the new email account but most times that yahoo pop up does not appear. We tried to match the setting of the windows 10 computer exactly and still doesn’t work.

Sometimes we get it to work using the above methods but fails after 1-2 weeks.

Any insights?

I have recently installed Thunderbird to help me with my overfull Yahoo account. I installed it using the default Yahoo authentication which seems to work fine. Since Yahoo exposes at most 100,000 messages in any one mail folder, and my inbox had over 250,000, my goal is to spread those out amongst a few different folders so that I can manage the inbox more effectively offline. To that end, I set up a couple of saved search folders, each of which selects e-mails within a two-year date range. Incidentally, each only selects about 1,000 messages at a time, not the 40,000 or so each of those time periods seem to contain. When I use my Ctrl-A shortcut to select the messages in one of the 'search' folders, then move those messages to my Yahoo mail folder under my e-mail account, the messages initially are wiped from the saved search folder, but after a few minutes they all return!

Incidentally, the saved search folder has the same name as the folder I'm trying to copy the messages to, but the search folder is under the Inbox, and the other folder is 'beside' (not under) the Inbox.

Let me know if there is a more efficient and effective way of doing what I want. Ultimately, I want well under 100,000 messages in my Inbox.

Thank you

When I delete mails they remain in the Gmail All Mails folder. I have set the setting to move deleted messages to Trash (attached) and I always Empty the Trash manually. In All Mail all the deleted mails are present. In the attached screendump from Gmail webmail it is the mails without any labels in front. (I have unsubscribed to All Mails in TB, but previously these messages would show up as only present i All Mail when searched in TB). Is there a synchronization problem? I have noted that there are two Trash folders in Gmail webmail: 1. in:trash (where Gmail webmail is putting deleted mails which do NOT show up in All Mails) and 2. label:[imap]-trash (where TB is putting deleted mails which DO show up in All Mails). Is that the problem?

Additional question: is there an easy way to permanently delete the mails without label i All Mails?

When I start Thunderbird, the same message is downloaded each time.

The status bar then reads "Downloading message 2 of 17," except that 17 is now up to 27.

Thunderbird remains in this state. No second message is ever downloaded.

When I close down and restart Thunderbird, it's Groundhog Day all over again.

Trying "Clear Recent History" has no effect on the issue.

I am on Thunderbird 150.0.2 (64-bit) on the release update channel. I'm on a Windows 11 HP Envy Laptop purchased in July 2025.

Hi, I use thunderbird as both POP and IMAP through gmail. I keep all my emails on my POP thunderbird desktop client. I use IMAP on my thunderbird laptop client, iPhone, iPad via Apple mail when remote, then download the emails to my desktop.

What I want to do is read emails and set them to archive on my IMA laptop, iPhone, iPad. I know Gmail tags the archived emails. How do I stop thunderbird from downloading the archived emails to my POP thunderbird desktop client?

Thanks! Art
