Thuderbird is failing the intial install and then does not allow me to import my previous thinderbird profile since it does not show all files in a directory of from another Mac M1 on my network where it is still functioning. See the following as some processing a failing in this listing.

If more information is needed then let me know otherwise I see if I have and the previous release and try to restore from there. Basic information is not in the system such mail accounts , message filter rules which I use heavily. I had four active mail accounts anw on two were found but was forcing me to logon into two of the four accounts.

Need a fix!!!!!

I have just started getting this error message when sending email from my @live.ca account. I do not get this message when sending from a @gmail or @company.ca address.

Quote: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Non-Compliant sender address. Code : -1. Please check the message and try again."

I can send and receive email using this address from my Android phone or from my Windows eMail client, so why is Thunderbird causing this? I have looked through all the setting and cannot find anything different from the settings for the @gmail accounts.

Thanks. Dave

Using Thunderbird 140.5.0esr (64-bit) email program, can not send emails. Get message: Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Connection from 69.119.30.125 refused. Have multiple email accounts - all get same response. Have tried several computers -all get same response. Can receive emails with no problem. I have spent several hours with my service provider [Optimum] checking/changing Server settings to no avail. They claim all my settings are correct and say the problem is not on their end. On the Optimum website email – I can send emails with no problem. I installed Outlook and set it up to the same servers and can send emails from there so it would seem Thunderbird is the problem.

Running WIN10 on 1 machine, WIN11 on another. Both same issue

Yesterday I opened Thunderbird to find that it was trying to download 8205 emails. 15 emails actually downloaded, there were no messages in SPAM folder. The notification at the lower right showed 300 more had 'downloaded' before I shut off the internet, went into Safe Mode, ran a virus check to find no threats found. No SPAM was recorded in Thunderbird when I went back online. There were, however, several files with large attachments so I don't know if this is a glitch regarding data vs. actual number emails because when I checked for updates (see attachment)

I discovered that since Version 115.4.2 I HAVE NEVER BEEN NOTIFIED OF UPDATES OR *FAILURE* TO UPDATE. AUTOMATIC UPDATES have been turned off and will remain turned off due to nearly dialup speed lack of bandwidth. I will abandon Thunderbird for having a fatal programming defect before turning on automatic updates.

My actual email provider did not show 8205 additional emails so I am concerned about a possible malware backdoor. Today 15 emails downloaded while the little notice at lower right said it was trying to download 113 ghost emails. I shut off Thunderbird and came here to post the problem. I will update Thunderbird, but need to know if there is a temporary file cache or some other hideyhole that the ghosts (or some attacker) might be storing godnosewhat so that I can either quarantine or delete them?

Hello,

I just switched to Thunderbird from Outlook and so far it seems nice but one problem when I click on the get messages cloud icon on the top left of the screen I receive no incoming messages. Now if I go to one particular email account (I have 8 email accounts) and right click and left click on get messages, new messages come in.

So my questions is, why doesn't all my mail come in when I click on the get messages icon? Am i misinterpreting this?

Thank you!

The receiving and messaging has been intermittent over the last few days. The latest message came in at 07:45 this morning

I had to install Windows 11 fresh because of multiple issues with my PC (I upgraded from 10 to 11 6 months ago). I installed Thunderbird fresh, and am trying to get it to see my existing data with is on my D drive. I browsed to the folder in Account Settings, but it's not showing up. I have years of mail and don't want to lose it.

There are too many options in the help for me to know which are actually related to my situation. I thought I was ready to do this, but am surprised at how difficult it is compared to the last time I did something similar.

Any help, even just pointing me to the right place to look for help, is appreciated!

Thanks!

I have installed Thunderbird as a first-time user on a new computer. I am able to receive emails but cannot send. I have the correct outgoing server settings and confirmed this with my ISP. They recommended that I check to see if my antivirus software is preventing from sending, so I uninstalled Firewall and it's still not sending. Can you assist in any other options that I should try to get emails to send?

Three weeks ago I attempted to migrate my TB profiles from a 2014 mini-mac to a 2024 mini-mac. I thought I did a better job of backing up my profile using CCC than I actually did. In the migration to the new Mac I lost all my subfolders from the last 20 years. Apple created a new Profile and 2 restoration Profiles on the new Sequoia based mini-mac. I wasn't familiar with these and panicked. I copied those files, took them back to the original mac and tried to follow Toad-Hall's method of restoring the subfolders recommended to bmack1 on 23/11/22. However, I failed to carry out the step of going up two levels in the path of the Library to copy the entire "Thunderbird" file and only copied the Largest restoration file. This in turn, "contaminated" the 2014 original Thunderbird mail profile and only an Inbox and Trash subfolder remained. Today, after 3 weeks of searching and reading the generous contributions of this community, I came across a post explaining that the "sbd files" will show the subfolder headings I created in the original sought after Profile. And I found it!!! My problem is I have re-read Toad-Hall's method of re-installing the original Profile and tried to carry that out to the letter by placing the old Profile within a Thunderbird folder and switching it with the current one. But it's still listed as the "Restoration qqg...file" and probably shouldn't be, but I don't want to go any further and risk losing it because I feel I almost have it. So any guidance would be greatly appreciated. Thank You.

TOPIC 1 In Betterbird there is the option to colour the email account. The only option in TB is to change the colour of the email envelope icon. There used to be a extension that achieved this but fell by the wayside in TB 115 I researched this on TB forum on reddit.... https://www.reddit.com/r/Thunderbird/comments/17unvb1/different_account_colors_in_thunderbird_115/

It made interesting reading and I did download the 'account colours' zip to install and see if it worked. Only thing is that I do not know how to install it........can someone brighter than me tell me how to install it and to remove it if it doesn't work. Many thanks.

Any user views on Betterbird over TB. The developer has done a great job and has one thing I do like and that is the ability to colour the highlighted email account rather than just the envelope icon. Experiences are appreciated so I can make the informed decision on which to use. Should I decide to use it how does one just port TB and its settings over to Betterbird.?

Thanks for views.

On Monday, 17 November 2025 the Security Certificate expired and I stopped receiving emails both on my computer and Andriod Device. As a result I am not receiving any emails through Thunderbird, but I can go to email host site to view them.

I logged in my computer tonight and clicked here and clicked there and the error message: "The certificate for mail.homebizmall.net is not valid for that server. Someone could be trying to impersonate the server. Create an exception but this could mean that someone has stolen your certificate and may be able to impersonate you."

So it seems the POP server and the SMTP server certificates were only valid for 3 months and I was FORCED to create the exception for both servers. Now I am worried the security has been breached.

By clicking here and clicking there, I stumbled on a few people who seem to have this problem, but each with their own limitations. My operating System is Windows 10 without the option to upgrade. I have not extended the security updates because I don't understand if it is just the operating system uploading to the cloud or everything on my computer and I am not prepared to do the latter.

Is it safe to leave the band aid on that I have used for the moment? Can I create an exception for the phone? Or is there a glitch that someone needs to walk me through fixing?

Thanking you in advance

I'm using Thunderbird with my GMail account. I've added all the GMail folders and can access them without any problems. However, I'd like to add a new folder. Is it possible to do that in Thunderbird or do I have to log into my GMail and do it there? I'm using Thunderbird 145.0 on Windows 10 Pro 64 bit.

MY email ISP is CenturyLink. I CAN use their WEB email site, so I know the password works. My old email had a Q.COM suffix, but CenturyLink recently said that they are abandoning that domain and that I now have to use MYCTL.NET as a suffix. I changed that in TB and now TB Fails to sign in! I have looked and looked at the TB config and still it doesn't work. Using POP for incoming email, have the correct POP server name, PORT and Encryption (SSL/TLS). I CAN ping pop.centurylink.net ....

Any suggestions would be greatly appreciated!

Thanks Nigel

I ordered some batteries from Amazon on 15/12/2024, 17:23. I presume they arrived, and I subsequently deleted the email. It has suddenly reappeared in my Unified inbox today, but not in any of the inboxes of the Unified Folders.

I am curious as to what caused this.

I must be doing something wrong. I am new to thunderbird, migrated from Eudora since I can't send mail with Eudora anymore.

I tried to configure Thunderbird as much as possible like Eudora, but ... it doesn't receive nor send mail. On the surface it looks fine, it seems thunderbird logs into the server, it seems it sends mail and checks for new mail, only I don't receive anything, nor send anything even though it looks it does. So what am I doing (or is going) wrong? (I can still receive mail with Eudora and today I checked and received 54 mails, none with Thunderbird)

if firefox is my designated browser and i open up the vivaldi browser and take a screen shot in the vivaldi browser, how do i paste the vivaldi browser screen shot in my thunderbird email? Thank you....b³
