Thunderbird — Fora społeczności

I have settings from Greenby to set up server connections for a new account. They are validated by thunderbird but, after, entering my greenby password, generates the error, below, which greenby claims is a thunderbird problem.

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

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

Now my greenby password works on their systems

Now I'm very new to Thunderbird so not familiar with the commands

Any one any ideas ?

I have a Windows 11 computer using Thunderbird which has been working fine until last email received was 19.30 UK time on Sept 14. Now Thunderbird will not send or receive e-mails.

Talktalk webmail is working fine via browser.

I have checked all incoming and outgoing server settings and they appear correct. However, when I test server connections, they now fail with error message.

I have checked Windows firewall OFF for 5 minutes, but no change. I have added Mozilla Thunderbird to permitted apps within Windows firewall - again no change. I do not use a VPN.

After years of using my TalkTalk.net account, nothing seemed to have changed, but suddenly today, all messages stopped. The message received is "Could not connect to server Thunderbid. Connection refused. Yet, I can receive the TalkTalk emails in my TalkTalk mail account. What could have caused this? Any advice would be much appreciated.

It was working fine on the new computer until yesterday. Now I get a pop-up box that says: ' Unable to connect The connection was refused when attempting to contact localhost.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure Thunderbird is permitted to access the web.

I can no longer use outlook due to being a basic BT email account user. Thunderbird recognised my account. But now says can find server. It may be my password is wrong in outlook, but it is so long ago, I have no idea of my original password. I’m using the BT Mail app on my iPad and iPhone which works fine, but want my past and present emails on my laptop as well. I’m using windows 10. Any help??

Almost anything I try to do with Thunderbird, even replying to emails requesting advice, I come up with errors, such as:

Sorry, you have been blocked

You are unable to access thunderbird.net

upstream request timeout

upstream connect error or disconnect/reset before headers. reset reason: connection termination

Environment:

• macOS, Apple Silicon (aarch64)
• Thunderbird: 155.0.1 (aarch64), Release channel
• Email hosting provider: Hostinger
• SMTP server: smtp.hostinger.com
• SMTP configuration: Port 465, SSL/TLS, Normal Password authentication

Problem: Incoming email via IMAP works normally, but Thunderbird cannot send any outgoing email.

The error is either:

“The connection to Outgoing server (SMTP) smtp.hostinger.com timed out.”

or:

“Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.hostinger.com failed. The server may be unavailable or is refusing SMTP connections.”

Troubleshooting already performed:

• Webmail can send emails normally.
• Thunderbird can receive emails normally.
• SMTP settings and username have been verified.
• Port 465 with SSL/TLS does not work in Thunderbird.
• Port 587 with STARTTLS was also tested and does not work.
• Tested with a different network/mobile hotspot — same issue.
• Tested Thunderbird Troubleshoot Mode — same issue.
• Updated Thunderbird from 155.0 to 155.0.1 — issue persists.
• Direct TCP connectivity from the same Mac was tested successfully:

nc -vz smtp.hostinger.com 465 → succeeded

nc -vz smtp.hostinger.com 587 → succeeded

Therefore, the SMTP server is reachable from the Mac on both ports, and the same mailbox can send normally through Hostinger Webmail, but Thunderbird fails to establish/use the SMTP connection.

Since sending was working normally before the Thunderbird update and stopped afterwards without any SMTP configuration changes, this appears potentially related to the recent Thunderbird update.

Could you please advise whether there are any known SMTP/TLS/socket issues with Thunderbird 155.x on macOS, or any additional diagnostics/settings I should check?

You can help by fixing my email. In the last 10 days it works only once in a great while. It keeps giving me a time out message. I have to go to Spectrum.net to get my mail and that is not what I am paying you for.

I get connection error: the certificate for imap.mymts.net does not come from a trusted source. Click to open security settings. I got my emails this morning but not now this afternoon?

Thunderbird is losing connection with mobile,charter.net. The message from Thunderbird is 'connection to mobile.charter.net timed out' Inbox mail stops, and some of the last mail has no content only the message header. This happens at the same time on Linux mint, Apple OSX and Win 10 pro with updates. When this incident only occurs with Thunderbird. The failure occurs for days at a time. Last outage was for 4 days. Started working again about 24 hrs ago and its just failed again. these are two separate email accounts. I also installed Outlook on the Win platform and Apple mail on Osx. They work just fine.

Receive the following error message whenever I attempt to reply to or forward an e-mail

"Send Message Error. Sending of the message failed. The message could not be sent because the connection to the Outdoing server (SMTP) mail.thorneplumbing.com timed out. Try again"

This has been going on for some time now, but does not happen when I use Thunderbird on my i-phone. Just on a PC. Please advise.

Thank you!

I keep getting authentication failure while connecting to server for different accounts every time I start thunderbird. It's usually just one and sometimes 2 accounts that fail. When I click on the individual accounts they start working just fine. I get this for yahoo, gmail, outlook and a couple of others. Something to do with the initial start of thunderbird I think.

Starting yesterday for no apparent reason TB has been unable to connect to my email accounts. (IMAP or POP). These include Roadrunner, Gmail and Outlook.

Any Ideas? James

Hello,

My internet provider is RCN. For the past couple of months, I’ve occasionally been getting the message, “Connection to server imap.rcn.com timed out.” As a result, I’m unable to receive emails via Thunderbird.

All my settings are correct. Usually, the problem resolves itself within 24 hours, but sometimes, like this time, it lasts longer.

Any suggestions? Best, Magda

I have been using Thunderbird for years. Suddenly, a couple of days ago, the sent and trash folders no longer show the emails in them. When I use Roundcube online, these files show up there as normal.

I have done considerable research online to solve this problem to no avail. Using AI, they suggest a number of things that I have tried, without solving the problem. Apparently, this is somewhat common. I finally got to deleting the send.msf and trash .msf. This did nothing to solve the problem.

This is very frustrating. What can I try next? I am using Win 11 and Version 152.

This past week I started having a problem accessing URL's embedded in my emails from the Thunderbird interface. When clicking on the URL reference, nothing happens. I have not changed anything in my settings recently. Running Windows 7. I know my email server is working since this works when using my AT&T mail handler. I did have an issue with a Trojan virus that was cleared up with Malware program (i hope). I checked all the parameters of my mail handler and saw nothing that might cause this problem.
