I-Thunderbird Isithangami Sokwesekwa

With just 2 email addresses that I have been using for years, I suddenly get this Undeliverable message when attempting to send emails using Thunderbird:

"The mail client submitted this message with bare line feeds, which cannot be sent via SMTP protocol DATA command and receiving system does not support BDAT"

I can receive emails from the 2 addresses fine, I just can't send to them through Thunderbird. When I sign in to Hotmail Outlook Live I can send and receive to these addresses with no problem.

I'm stumped! Any ideas? Can I reset Thunderbird?

Thanks

My Thunderbird has been working properly for about 30 years, but now refuses to open. Message received says 'Authentication failed'. This happens repeatedly (for at least 20-30 times) and appears to relate to my password. It suggests 'Retry' or 'Enter new password'. The 'Retry' repeats as before so I check the Saved Passwords and enter the one saved. I get the same message. I am using Version 115 and have been for some time.

Could this be related to a change of Profile? There must be a way to reset the password? I have checked all the settings and no errors appear, all settings confirmed.

I have thought about a Recovery Mode and seem to remember seeing a message that I do have that. I just don't know how to access it.

Delivery Status Notification Does Not Work!!! and hasn't for about a year~! I have the latest version of Thunderbird, Ver 103.3.2 (64 bit) ! I am wondering if there if it's my Breezeline email server or is there an issue within my About:Config properties?

Hi everyone, I am far from a proficient T-bird user so stick with me... My C. drive has a massive amount of space being used by T-bird, over 67Gb. My account is the only one on this machine and it is hosted with Inmotion Hosting. I've confirmed with them that they see me as an IMAP account and my settings are IMAP also locally. I did find under settings in Sync and storage a setting for 'Keep messages in all folders for this account on this computer'. The check mark is checked so it will be keeping all messages. Under Advanced (to choose which folders are 'kept' locally, there are options for all of my folders, some are back to 2014. My question is if I uncheck this box so that the files are not kept locally, will it for some reason expunge the files from the servers within Inmotion? My hesitation is due to talking to them about 14 months ago and I was given erroneous info on POP vs IMAP and subsequently some emails being lost on a corrupt PC. I'm a bit gun shy to execute the unchecking and then the delete of the huge local file.

File path is:: C:\Users\Practice Manager\AppData\Roaming\Thunderbird\Profiles\kn769u8t.default-release\ImapMail\secure251.inmotionhosting.com

The secure251.inmotionhosting.com is the big pig with 65.4Gb.

Any insights and help would be greatly appreciated.

Hi, As of yesterday I am unable to send emails out. I keep getting this message below. I have gmail on same computer and that works fine. I am able to receive emails but can't send. Please help

Hello

When I restart my PC (windows 10) and open Thunderbird it takes over an hour to start up. I get the 'Thunderbird is not responding error' all the time and it is very very slow. Even when it eventually starts up, it crashes every time I click on the screen for about a day before it gets back to normal. I have just been leaving Thunderbird open but I need to restart my PC every now and then.

I have no Antivirus apart from Windows Security and have added the entire contents of the Thundebird file within the :C drive (Local Disk) to the exclusions.

When I start my windows PC in safe mode with networking, Thunderbird starts up immediately and I have no issues, but I have no idea what is causing it to be so slow when in normal start up and how I can fix this issue?

I have been having these issues for a long time now and have tried everything I can think of.

Any help would be greatly appreciated, have used Thunderbird for years and it would like to stick with the platform!

Many Thanks,

I am trying to send an e-mail to an address I have sent before and get this message: Sending of the message failed. An error occurred while sending mail. The mail server responded: 28AIcTF2017255 This message has been blocked for containing SPAM-like characteristics.. Please check the message and try again.

I just upgraded to Mac's latest OS 14.0 (Sonoma.) Thunderbird will not load. When I run the application I get a beachball and an "application) is not responding" message. I have tried rebooting and all the "typical fixes.)

Is there an update coming? Something that I can delete to make Thunderbird work?

Hi there. I'm a non-developer but I've been using Thunderbird Beta for a while. I'm not enjoying the current updates (no drag and drop function to move messages between folders!) and would like revert to regular Thunderbird (currently 102.10). I use Backup Thunderbird but I don't think it will load into an older install of Thunderbird. Advice for a safe way to migrate to regular Thunderbird without losing data? Thank you!

I'm converting from outlook and I'm wondering how to jump to a particular letter in the alphabet with scrolling to get to it when the emails from sorted by alphabetical order. In outlook you just click on the alphabet on your keyboard and it takes you right to the beginning of the emails starting with that letter. Just curious if thunderbird does this or if there is an add-on or shortcut to get there. Thanks.

Today my 102.0.1 has disappeared. TB has worked for me for decades including now on 102.0.1 which is the latest version. I've downloaded 102.0.1 again but still doesn't show up.

I never seemed to have a problem with my Mozilla Thunderbird but shortly after the last Mozilla Firefox update my inbound email thru Mozilla Thunderbird come into my inbound email box as DRAFT Messages. this is a big problem because I can't reply and or forward because there is no (((send))) showing up anywhere. Nobody seems to know how to solve this problem so it must be a first. My wife is on the same Home network as I and she has no problem like mine. I hate to reinstall Thunderbird because I don't know if it would interfere with all here computer info especially with her Thunderbird which seem to be OK (( No inbound Draft email Messages )). I use cox as my IP and mail coming into their email does not have a inbound draft problem, nor does AOL or GMail just Mozilla Thunderbird.

Hello! I was wondering if you guys could help me get set up on Thunderbird. I'm having some trouble getting logged in with the "Set Up Your Existing Email Address" section. I'm certain I'm typing in the right login info but it says it is "Unable to login at server.

Unified Folders in Thunderbird 115 for mac no longer works. Useless! Computer Tech specialist here and have been using Thunderbird for ages. With this latest version, the inbox, sent, etc etc etc no longer display as unified. The Unified Folders category when ON shows as its own item in the left column with a single empty inbox! Scrolling up and down to each account for each subfolder is a waste of time!!! Hope you fix this ASAP!!!!! Unified folders works fine in 10.12.13 but I cannot got back to that due to your system.

What must I do in order to enable address book address information. Now when I try to change address information it is as though my keyboard as been disconnected. thanks

Until yesterday I could click on 'Inbox' and it would shows all emails from all 3 accounts I have set up. There was an update yesterday (102 1.2) Now although I can go to each email account individually, when I click on 'Inbox' it only shows emails for one account.

It also seems that search is also not functioning across accounts.

I changed the email login for my primary account, thinking thunderbird would still show the years of saved messages in folders for the original account. They have gone away, but WHERE TO?

My email account with Thunderbird was working fine until I rebooted. Now I'm getting the Account Setup page when trying to launch Thunderbird . As I am not a technical person , I need step-by-step instructions how to restore my email account . Your help is much appreciated .

so i have a backup local folder where i copy all the mails from the inbox of an account from, and another local folder where i copy the spam folder of an account from, but i am doing that manually, and i don't just delete the now backed up mails. so next time i have to find out first where the cutoff is, before i start selecting and copying again, because otherwise i'd be backing up duplicates.

is there an easier way to avoid duplicates, or a synchronization function that takes care of avoiding duplicates for me?
