My wife & I have the same PCs running Windows 10 & Thunderbird 115.11.0 (32bit).

We have a hosted web-site that also supports email, and we each have an email account (eg neddy@goon.com.au & minnie@goon.com.au). I've checked that both our POP server configurations are identical but despite that about once a week minnie@goon.com.au receives a warning to add security exception but neddy doesn't. This started happening two weeks ago after a years error free running.

The host has checked that goon.com.au has a valid SSL certificate, so what could be causing the discrepancy and how do I set about fixing it please?

I always use Mozilla Thunderbird for email. Today, it would not send outgoing email. Any email gives me a failed message: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 665754780026FB52). Please check the message and try again."

My ISP insists the problem is not with their server, and I need to have Mozilla correct it.

Some mails always end in spam folder no matter which settings I have tried for example collected adresses or check/uncheck spam settings. For a test I have two hotmail accounts. When I from thunderbird send mail from one to the other, it ends in spamfolder. But if I from the same mail account from outlook.live website send mail to the same account, it doesn't end in Thunderbird spam folder. Besides this many other safe and regocnized mailaccounts recently starts to end in spamfolder. Can any thing be done?

Hi, I´ve some Outlook accounts with two step verification login. Anytime I open Thunderbird I´ve to verify myself by selecting a number on my mobile. Is it possible that Thunderbird get´s directly to my outlook account without that veryfying process? Thanks for answering.

Our app sends an email advising the specified individual to note a series of images presented in three rows of nine. The rows display in Gmail via Windows->Chrome, via Android, and iOS with a Yahoo account.

But not in Thunderbird. This is a serious issue as I believe I have followed all the correct settings including in-line display, and yet for some reason, Thunderbird does not display the images.

Any suggestions are appreciated as I am baffled since Thunderbird has been my go-to email client for years.

I installed Thunderbird and downloaded the mail (IMAP server) to the mailbox, but at the same time the program deleted all the mail from the server!!! I can't find anywhere in Thunderbird how to turn it off so that the program doesn't delete messages from the server. Someone suggested that you should turn off "the selected folder will be available in offline mode" in the Synchronization tab. I did it, but it didn't help and I turned it on again. Now I don't have my messages anywhere, neither on my computer nor on the server. Rescue news from ten years - where are they????

I have an issue trying to configure a secondary email account, for a non-profit I do some work for. It was ok in the past, though I recall was tricky to set up on TB a couple of years ago. But now it has ceased to function after I migrated TB profile (successfully apart from this issue) no matter what I try. I’d be grateful for any suggestions. As is the case with many non-profits, there’s little tech support, but others can use the email account ok. I think it may be a TB issue as I have been able to set up the account ok with MS new Windows Outlook app (lame, but better than Mail…low bar). I’d rather have this account on my TB client along with the others I use. And the issue is replicated on two of my PCs. TB account set up reports “can’t detect settings from host server”. I found a support thread link text, which says “The failure to detect settings is rather common where hosted domains are concerned. Mostly because everything is done to a price and most of the things around encryption are done in a halfhearted manner. As is the server setups for mail. However by faithfully copying the settings from the provider as to domains server name and ports it should work.” So I did manual configuration – copied the settings from the successful Outlook set up, but no dice – all I get is server time out message. Settings are: IMAP server: mail.XXXX.org.uk Port 993 Security SSL/TLS [earlier working settings were STARTTLS port 143] SMTP server: mail.XXXX.org.uk Port 465 Security SSL/TLS [[earlier working settings were STARTTLS port 587] And using Normal Password for both; I tried Autodetect too but no good. I’ve see a suggestion that turning off the firewall (Norton) might work, but I’m reluctant to do that and doesn’t seem to make sense that would cause the issue. I found another suggestion that apparently works for some people - leaving password blank on setup. https://support.mozilla.org/en-US/questions/1399690. Before I try, are there any other suggestions or ideas? Trivial matter in the long run, but bugging me. Thanks

Hi,

I am facing an issue with Thunderbird.

I integrated my email address but there problem is the new message is giving "Undelivered Mail Returned to Sender" but I can reply and receive the emails.

Please guide me about it.

Many Thanks

First, I am supporting a family member, who has TB configured on two separate machines. Configuring for Comcast IMAP+SMTP, in the usual manner; nothing esoteric about that, all very routine.

Machine A seems to be working okay, no errors. TB up to date on this machine, connected over an ethernet wire, if that makes any difference.

Machine B, getting spam prompted over IMAP 1014 errors. No other information is provided than 1014.

I have tried dropping the account configuration hundred percent, restarting TB, re-adding the account configuration, to no avail. Still spam 1014 errors.

I did happen to notice TB needed an update, so I did that as well. Still 1014 errors.

I have also tried dropping that email saved password from the saved passwords, and responding to the subsequent re-enter password prompt. Also to no avail.

What if anything might have changed, and how can we contend with this? What is so corrupt, do we need to be mucking around in any AppData files, roaming files, etc?

We are not the only ones, apparently, to have bumped into this issue. Not sure if this is also Comcast specific, since a recent TB and/or IMAP specification change, i.e. maybe we try with a gmail account, for instance.

Wondering also, is it IMAP and/or Comcast somehow tieing Machine A to the IMAP and not releasing that association? Knowing a little bit about IMAP in this regard. And/or somehow now prohibiting Machine B+ from establishing a connection?

One of my two gmail accouns has suddenly become impossible to access (cannot receive, cannot send). T'Bird produces an Authentication has Failed notification, after a Google Window headed "Sign in to Mozilla Thunderbird Email" which refuses to go away. Clicking on the 'help' or 'privacy' options in that google window produces no more than a blank window but then "Sign in to Mozilla Thunderbird Email" reappears a few minutes later. My other gmail account doesn't have this problem, so I assume it's not gmail but it's T'Bird.

What's going on?

(BTW signing into this Support resulted in an email "New sign-in to Mozilla Support" warning "New sign-in to Mozilla Support to Firefox on Windows 10". Trouble is, I'm on Windows 11. Trivial maybe, but telling maybe.)

Hi, 3 weeks ago I suddenly could not log in to my email without errors.

First I get a Google screen "Choose an account" showing the three Gmail accounts I use. I select the first one.

"Mozilla Thunderbird wants to access your Google Account". This refers to calendars. I take the Allow option.

Then I get the message "Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to localhost. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

When I close this window I get another Google screen .

"Mozilla Thunderbird wants to access your Google Account". This refers to i) mail, ii) contacts, and iii) calendars. I take the Allow option.

Then I get the same message message "Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to localhost. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

This process cycles through the other two emails. Then I get and authentication failure message.

I have seen hints that this might be a certificate issue but I have tried in vain to find certificates stored in Thunderbird.

Any help approeciated.

Thanks

I've appreciated using Thunderbird for an ad-free Hotmail experience for quite some time. I've changed my Hotmail password every few weeks lately and Thunderbird worked fine when I entered the new password at the prompt when Thunderbird started.

Just now however, I needed to get into my Microsoft account that uses the same password as my Hotmail account. My login to Microsoft failed. Trying to understand why, I looked in Thunderbird at the saved password for Hotmail's server:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All

https://outlook.office.com/POP.AccessAsUser.All 
https://outlook.office.com/SMTP.Send offline_access)

The saved password was a 464 character long ASCII string totally irrelevant to the password I'd selected for Hotmail and Microsoft.

I went through the password change process for Hotmail, was then able to get into my Microsoft account and restarted Thunderbird. As usual, Thunderbird asked for the new password. I entered it and was then able to receive new mail from the Hotmail server in Thunderbird. However, again, the saved password in Thunderbird for Hotmail was not the password I'd entered.

Next, I deleted the saved passwords in Thunderbird, restarted it and this time it prompted me to be sure I'd downloaded it from a reliable source. I've never seen that prompt before. It came with my Linux Mint installation, so I thought it would be safe, but again there's an irrelevant password saved for my Hotmail account.

It's like it eventually changes my password for Hotmail and Microsoft since I can get mail through Thunderbird with the odd password it saves, but if I use what should be my password for Hotmail or my Microsoft account via a web page interface, the password doesn't work.

I'll have to stop using Thunderbird if this continues.

I have an email conversation that's gone back and forth many times, with the other party including useful links for me. I noticed today that links are only live (blue, clickable) in the most recent email, if I scroll down to past emails in the chain, all links are plain text and not clickable. How can I make them all clickable please?

Hello, I have problems signing in Thunderbird, it asks me for a password and though I am sure I enter the correct one it does not give me access and there is no way to put a new password also so how I am supposed to use Thunderbird again. I can do that with roundcube but Thunderbird does not give me access and to be honest I am a bit frustrated.
