Thunderbird: форум сообщества

Email will not send. Message-- "Sending of the message failed. An error occurred while sending mail. The mail server responded: Email rejected. Please verify that your email address is correct in your account settings and try again." I am not sending to another person but testing with my personal email. Thank you.

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,

Dave

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 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.

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.

Running Thunderbird 128.14.0esr (64-bit) via 64 bit Win11 Pro v. 25H2 on a Dell Inspiron 16 plus, Core i7-12700H @ 2.3 GHz, 24 MB cache, 40 Gb RAM, 877 Gb free on a 1.8 Tb Crucial T710 NVMe SSD drive. Integrated Intel Iris Xe graphics using 20 Gb shared RAM.

I have 5 email accounts (AOL = Yahoo, Yahoo, GMail, Verizon = Yahoo & MSN) each with a distinct IMAP server description. I also had my daughter's AOL account in the same TB profile.

On 5/9/2026, I foolishly entered my credentials in an AOL request for verification of her account (to allow TB access). As result, my jawarters@aol.com account and her jmwarters@aol.com account somehow became linked. Her email account in TB now contained only messages which were duplicated in my email account.

I deleted her existing jmwarters@aol.com mailbox and attempted to recreate it in Account Settings. Despite entering distinct IMAP settings (user name = jawarters@aol.com, imap.aol.com, port 993 and user name = jmwarters@aol.com, imap.aol.com, port 993) and having distinct SMTP settings with the user name in the Description, the recreated account again downloaded my emails into her TB account. The same happened when I opened TB on my desktop.

Interestingly, TB for Android v. 18 kept both accounts separate. I attach a copy of the TB Android k9s settings file which shows the same IMAP and SMTP settings as the laptop / desktop TB.

Help solve my self-imposed problem! Jim W

For some reason since reinstalling my Thunderbird every time I try to sen e-mail I get the error "Sending of the message failed. An error occurred while sending mail. The mail server responded: <SantoshS1@vbeyond.com>: Recipient address rejected: Access denied. Please check the message recipient "SantoshS1@vbeyond.com" and try again.

They are perfectly valid addresses, as they are generated using Reply. This did not happen before I was forced to reinstall from scratch. I suspect it may be some sort of issue with my account configuration in Thunderbird, as I had to recreate that.

Not sure what has happened to my PC but lost my Thunderbird app.

Reinstalled but cannot get my emails working again. I only get emails up to 13th May 2024; I guess when TSO Hosting finished?

I am now on 123 Hosting.

I have a note that SERVER for both i.e. Incoming and outgoing is:-

sxb1plzcpnl503269.prod.sxb1.secureserver.net (smtp as prefix)

Where and in what format do I enter theses server details.

I think I also need to get into cPanel but the URL I have will not work:-

https://sxb1plzcpnl503269.prod.sxb1.secureserver.net3 (:2083)

Sorry but I am confused; don't get old!

I can receive outlook e-mail but I cannot send from Thunderbird. I am asked for a password for the specific Microsoft server. I enter my Microsoft account password but this does not work. Security setting is STARTTLS withNormal Password authentification. My other Thunderbird non-MS e-mails are problem free.

This is what I get when I click on email link. I can't delete it. This has to be solved before I can get to my second problem https://webmail.spectrum.net/mail? context_token=eyJza3NpZCI6ImNvbnRleHRfdG9rZW5fc2lnbl9rZXlzZXQiLCJza2lkIjoiNmJkYzZiMTEtZjBiZS00ZGFlLTliOWUtY2RkMGMyNWE5ZmUyXzIwMjAtMDEtMjRUMDcuNDIuNDQuMzQwWiIsInNlY3BvbCI6ImNvbnRleHRfdG9rZW4iLCJraWQiOiI2YmRjNmIxMS1mMGJlLTRkYWUtOWI5ZS1jZGQwYzI1YTlmZTJfMjAyMC0wMS0yNFQwNy40Mi40NC4zNDBaIiwia2V5VHlwZSI6IlJTQSIsImFsZyI6IlJTMjU2IiwianRpIjoiYWU2MzMwZDYtNTBlZi00Mjk3LThlOTMtZDUxOWVjZmMxMjdkIn0.eyJzdWIiOiI5RTJGNzAxQi02N0IyLTRBQkYtODA3Ni00RkUzRUIxMzdBRkQiLCJkZXZpY2VfaWQiOiI2NTUzMDYyOS01YWJmLTQ0MWQtYTE1OS04Njc3ZDc0ZTU1NzUiLCJzZWNwb2wiOiJjb250ZXh0X3Rva2VuIiwiaXNzIjoiY29udGV4dF90b2tlbi1pc3N1ZXIiLCJpZGVudGl0eV9ndWlkIjoiOUUyRjcwMUItNjdCMi00QUJGLTgwNzYtNEZFM0VCMTM3QUZEIiwicHJlZmVycmVkX3VzZXJuYW1lIjoiampmbHlubjUwQHR3Yy5jb20iLCJub25jZSI6IjE0NjY2MTM2NzYzODIwMzY5Mzk2NDMwMzI1ODQzMiIsImNsaWVudF9pZCI6ImNvbnN1bWVyX3BvcnRhbCIsImF1ZCI6ImNvbnRleHRfdG9rZW4tYXVkaWVuY2UiLCJhdXRoX21ldGhvZCI6IlBhc3N3b3JkIiwibmJmIjoxNzY5ODc5NzgwLCJhdXRobl9zb3VyY2VfcG9ydCI6IjU5ODc1IiwiZ3JhbnRfdHlwZSI6ImF1dGhfY29kZSIsImRsYV9wZWVyX2p0aSI6ImFjNTZmMGEzLTg0OGMtNDNhOS1hOTUyLWNlNzllNDM4YmI5MiIsInRydXN0ZWRfY2xpZW50IjpmYWxzZSwiYXV0aF90aW1lIjoiMTc2OTg3OTc4MCIsImF1dGhuX3RyYWZmaWNfb3JpZ2luX2lkIjoiNjguMTcyLjE2OC4yNyIsImRsYV9wZWVyX2V4cCI6IjE3Njk5NjYxODAiLCJleHAiOjE3Njk5NjYyNDAsImlhdCI6MTc2OTg3OTc4MCwianRpIjoiYWU2MzMwZDYtNTBlZi00Mjk3LThlOTMtZDUxOWVjZmMxMjdkIiwiYXBpX2d3X2RldmljZV9pZCI6IjY1NTMwNjI5LTVhYmYtNDQxZC1hMTU5LTg2NzdkNzRlNTU3NSIsImlzQ29udGV4dFRva2VuVFRMT3ZlcnJpZGUiOnRydWV9.SkxhnFtRLxHTpXXn5_kDX8nBISuPu3wdpoNFwTKLtmUadL29D40rNMHlmEOOa2LbGFVi8qlEWnscUMV8WXGLF02RFhSsEMFtBbXGpB9XUy6q_YW5FRJo1su5AJxboh1LMastJ39rdqnooQsnvA5_Mmy4NDBZrb1bQCmzXn3wiLsiBDMxorQ8Kk45CEWL6Bz09Z8EltuEQ2yVN3FGTGqAeU2i5-qNv12kzgimIu4TbDyE2DIi6_AKenLGc1kXlcZ8oxGjUEbJm1AThmpNbGF9WJ7d55_JQyfGWvEMIYNOtAiPaNNRCF1AlcBP3TAH34L1uI49Ve6C0SvidbRu2jYDuQ&referrerAppVisitId=202601311716P-753ab3c2-c22c-44cd-865d-2b77307fabfa&referrerAppName=SpecNet&referrerAppType=Web

Bei einem zweiten eingebundenen Mailkonto funktioniert Thunderbird einwandfrei.

Hi, very nice of you to listen to my problem. It already startet some days ago when I realised that it took very much time to receive mails, in some the content still kept hidden. To work with the about 60 mails listed in the Income-folder, and select some to read the text I was surprised to realize, that in the next moment the folder was empty, none of the mails could be seen on my Windows laptop. I had to switch to the mail-server with Vodafone to see me mails. This situation occured with all folders on 2 Laptops with Windows 10 and windows 11. What could I do ?

Good afternoon.

The message was composed using a translator I have 3 mail for work. 1 personal, 2 shared There are no problems with my personal email. I can't send messages from two other emails, and I get an error

Error translation "Error sending message. Error sending mail. Mail server responded: Error: send AUTH command first. 1777978756-Gxds2c0SZiE0-r8k7j8Ju. Make sure the email address you specified in your account settings is correct and try again."

Hi. I have four gmail accounts and use a desktop pc runnings windows 11. I have been using thunderbird as my desktop email client for many years, but recently, something has changed. My incoming emails are not formatted correctly and the links in them do not work. I'm not sure I am saying that correctly, so I will attach a screenshot. I would love some advice on how to fix this! Thanks, Cheryl

I have just set up Thunderbird on a new Windows 11 PC. So far as I can tell I have filled in the server details correctly. I can receive incoming mail. However, it fails to send emails out - I have tried a couple which I know are correct. Error message is: Sending of the message failed. An error occurred while sending mail. The mail server responded: <<snip>>: Relay access denied.

Please check the message recipient "<snip>" and try again.

(I've removed the actual mail address from the error message.) I've read the answers to previous versions of this query and made the correction as suggested. This hasn't helped. Any suggestions please? Many thanks, Roger Moore

I can receive emails fine. But when I attempt to forward an email TB tries using the wrong SMTP server, and an email address that no longer exists in any email account. For example, the email is in a yahoo account and TB tries using a gmail server. I have email accounts (in TB) with gmail, yahoo, rocketmail, AOl, and verizon.net. I have verified ALL server settings for each account as correct. I first experienced this in ver. 140.8.1esr(64-bit), and updating to 140.10.1esr (64-bit) did not resolve the issue.

Just installed a new hard drive and windows 11. Installed Thunderbird, which I have used for years. Began receiving e-mail right away. Have tried to send several e-mails but I get an error message saying mail server responded: relay access denied Please check message recipient and try again. The e-mail for the recipient is correct and I have tried to send to others with the same result.

Do not know if it is a windows error, an smtp error or a Thunderbird error. My web host gave me the proper settings for incoming and out going mail. They are the same as I had for windows 10 which worked forever.

Can you help? Thanking you in advance.
