When I attempt to send email I get the following message: Sending of the message failed. The message was not sent due to exceeding the allowed number of recipients. The server responded: Policy-SC01 You’ve reached your sending limit. Don’t worry, you can send again soon..

TB is sending most of my email to the wrong folder. I had 21 message filters, but then I noticed that a lot of things were going to a folder named "bridge" for no apparent reason. I looked at the filter log, but there was nothing in the log for the last few months.

I did have a filter sending certain messages to the "bridge" folder, but TB is sending things there for no reason. I disabled all 21 message filters, and it is still doing it.

I have version 155.0 and I'm using Windows 11 25H2.

How can this be fixed?

The message filters simply are not working. Not only are they not directing incoming messages to the correct folders, they are also moving some messages in a folder to another folder without a rule!

I did a complete review of my message rules, cleaned them up, had some success, but the next time I opened Thundered to check email, some messages were still directed to the wrong folder. I have used Thunderbird for years, know how to use/create message rules and had no trouble prior to 155.

ALSO - tried reloading Bird 154, but it wouldn't do it because of "Profiles." Bad move there. Frankly, those multiple Profiles are a pain in the butt in Bird and Firefox, a perfect example of if ain't broke, don't fix it.

Hi There,

I am trying to add my new email address to the thunderbird app for Windows and running into issues syncing it through IMAP settings. The process seems to go smoothly until it gets to the point where I have to enter my email password. After I enter my password and hit "continue" I get the following error message:

Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIIOService.newURI]

I have attached the screen shots of my process, as well as the IMAP and SMTP settings from my email provider.

Any help I can get in troubleshooting this error would be greatly appreciated.

Thank you,

Tim

My computer recently updated to Thunderbird 155.0. The Local Folders did not move along with all my contacts. I have backed up mu Local Folders and contacts into a file into a file. Using the forum I have cut and pasted all of these into the Local Folder in the new Thunderbird but they are not there in the new Thunderbird. Please explain how to restore them in the new Thunderbird. I would suppose i will have the same issue with Address Books and would appreciate help there as well. Many thanks for your help!

for a week or so now, I get the following message when trying to send" Sending of the message failed. An error occurred while sending mail. The mail server responded: Transaction failed Reject due to policy restrictions. For explanation visit https://postmaster.gmx.net/en/case?c=hi&i=ip&v=149.102.242.95&r=1Mirna-1wPNAF1v2y-00h7M4. Please check the message and try again."

receives fine, will not send

I have an issue when trying to forward an email that contains an attachment. I receive the following error message:

"Sending of the message failed. There was an error attaching the file. Please check that you have access to the file."

I am using Thunderbird version 152 on Windows 10 Pro.

This issue only occurs when forwarding emails with attachments. Other email functions appear to work normally. Has anyone else encountered this issue? I would appreciate any help or suggestions. Thank you in advance.

Hello,

A folder (Local Folder) shows that I have 20 UNREAD messages. I don't care about them and want to mark them all as READ right away, so I right-click on the folder and select “Mark all folders as read,” but NOTHING happens! I search for the “unread” ones, it finds them, I select them all and right-click, but no options are available! What’s the point of the search and multiple selection in this case?

Please either tell me how to do this in a single step or fix these usability bugs.

Best regards

My recollection is that prior to a recent automatic update to Thunderbird 140.12.1esr (64-bit) when I had a message composition window open, there were "SEND" button and possibly a "SEND LATER" button (to the left of the addressee and cc addresses in addition to the keyboard shortcuts (CTRL ENTER and CTRL SHIFT ENTER).

Following the update, there is no longer anything to the left of the addressee information. I have checked the toolbar menus, and there do not appear to be any button options. I can still send messages, but the lack of the buttons is a hindrance.

I recently (unwisely) refreshed my WIndows 10. On restarting I had to reinstal Thunderbird. I thought I'd be able to recover all my old emails by importing the old profile from Windows.old, but I've had some problems: 1) I can't identify which profile was the most recent. 2) The info from each profile has remained on my Thunderbird, although I though it would be overwritten by the next profile I imported. 3) I've tried importing them one by one, but none of the old profiles is the one I was looking for, with all my sub folders. I need the old emails for work, invoicing and tax calculation purposes. I've now been sitting in front of my computer for a couple of days in a cold sweat, the desperation building quietly. Can anybody help?

Every time I start Thunderbird it takes several minutes and sometimes doesn't start up. Once it does open up, emails do update new ones but if I go to account settings and select anything it hangs up. If I click on it, grays out and gets a message Thunderbird not responding. I have to open task manager to stop the program. Why aren't the emails on my email server get deleted/ moved updated when using Thunderbird? It seems like the only thing that happens only gets changed on the device I made changes to only. (computer, or phone or laptop)

Installed Thunderbird Setup 153.0.3 and npw when running t-bird get a prompt asking abut a 'thundermail" address. Please advise.. What is "thundermail" and why is it in my way? I am a regular donor to T-bird sent several, emails addressing the "thundermail" weirdness and thus far no reply. .
