Cannot send messages. I get an error code:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: RBL restriction: Blacklisted by Internal Reputation Service - 73.62.119.4.

This is a recent abberation. I've updated to the latest version of TBird. But cannot understand this message or why I get it. Please help as I forward/send many messages daily.

Thank you

Attempting to install Thunderbird on an additional desktop using same address as my original computer has. That was my question:

Lin answered: Please quote any and all error messages you see, in full, verbatim. Screen shots would be OK.

Who is your email provider?

Have you compared all account settings, not just the email and password?

Here's my answer to those questions: "Authentication error" "probably wrong configuration, username or password."

My email provider is MTA (Matanuska Telephone Association) Yes, I currently use Thunderbird in my other desk top and it works fine.

Hi, I use thunderbird as both POP and IMAP through gmail. I keep all my emails on my POP thunderbird desktop client. I use IMAP on my thunderbird laptop client, iPhone, iPad via Apple mail when remote, then download the emails to my desktop.

What I want to do is read emails and set them to archive on my IMA laptop, iPhone, iPad. I know Gmail tags the archived emails. How do I stop thunderbird from downloading the archived emails to my POP thunderbird desktop client?

Thanks! Art

I have multiple accounts in Thunderbird. I use Unified Folders for inbox. If I click "New Message" while in the Unified Folders view, the message will send from my default account, which is bill@billbauman.com. But, if I want to change my send from account to bill@ntur.ai, where I have a signature configured, the image in the signature fails to load. But, if I change my focus to select the inbox for bill@ntur.ai and click "New Message", the default send from account is now bill@ntur.ai, and the image in the signature loads just fine.

The image is publicly hosted and loads fine in any browser: https://images.int.dreamhosters.ai/account-482257/ceb3563cdab64978.jpg

I tried to make this as simple as possible for debugging, so I change the signature to just the image. Here is the code: <title>Email Signature</title>

I am running Thunderbird 147.0.2 (64-bit) on Windows 11.

I can make a screen recording demonstrating the behavior.

Does anyone have a solution for this?

Thanks all in advance!

I have just acquired a replacement PC and installed Thunderbird, and (as happened on previous occasions) I am unable to send emails because the outgoing server settings that were automatically detected are incorrect, and even feeding in those I recorded on the last occasion does not work. I have had a long conversation with somebody at Plusnet Help Desk, who agrees that the outgoing server should be mail.care4free.net and the port number should be 25, and the connection type should be SSL. He also thought that on my "Account settings" screen there should be an option "Account actions" through which I may be able to solve the problem, but this is not there. I think that last time I had this problem, some genius on this forum managed to solve it, and hope that this will again be the case!

Hi everyone!

I'm trying to log into my email account on the domain example.com via SMTP. The email account is with yandex.ru. When I try to authenticate, it says the SMTP password is incorrect. I decided to try through Outlook, and it worked. What could be the issue?

I have email [edited from public] @riverplazatravel.com purchased through Rackspace For days, on my emails through Thunderbird, I'm receiving emails but SENT emails disappear. They aren't showing in TRASH anymore, or SENT....they are disappearing and I have to check with my customer and they aren't receiving them. Big problem. Please help I've spent hours of research and dont understand much of that and so many are outdated. I've messaged and called various people. Your email was provided to me by Rackspace.

I live in Germany and use t-online for my email. I can receive emails but not send. I have tried to fix it myself but nothing I do has worked. I don't understand all the technical stuff, so this is maybe my problem. Can anyone help me? PLEASE

Maybe there is someone near me in Germany (Obertshausen) by Frankfurt that can Help. I speak German so this would not be a problem.

It's been almost a week now, and my 2 Microsoft email accounts will not connect to Thunderbird anymore. All was fine for years, but something changed that I can't figure out!?! I have gone to my Microsoft email server and checked that my passwords still work. I even updated one and it works on Microsoft server but not Thunderbird's!?!? I even deleted one email account from Thunder bird to re-install it, but when I tried a fresh re-install Thunderbird still won't connect to Microsoft server??? I'm at my wits end, and may abandon Thunderbird completely if someone there doesn't help me connect!!!

I have been using Thunderbird for many years. I just got a new computer and installed Thunderbird onto it. I have several email accounts for personal, business and clubs so this makes it easy to keep track of. I have some gmail accounts and 3 different yahoo accounts. Now when I get an email to one yahoo account it prorogates to the other two. This never happened on the old computer do you have any idea how this happened, and more importantly, how do I stop it?

When attempting to send a web address under "file" tab using Thunderbird, there is an offering "email Link". "email link" does nothing with Windows 11 but worked with Windows 10? I have to copy and paste to send a web address to a mail recipient.

Hello, and thanks for the read...

ISSUE: Every day I have to call the telecom ROGERS that took over for telecom SHAW, turn IMAP and Pop3 on 9 Email accounts (they lost 1). Sometimes the 1 to 2 hors chat w/ a human turned it back on will not last long.

DETAILS:

1. I can receive outside Emails *because I can't send using Shaw/Rogers, checking for Email, just hangs at trying to login in to any of the 9/10 emails.
2. When I can get a support person to check, they tell me that IMAP and POP3 are turned off.
3. They will tell me they re-enabled it. But it doesn't enable for me.
4. It all works OK when using the online webmail Zimbra. However, I need to check 3 of the 9 email accounts every hour, others every 6 hours, and others once a day at boot.

QUESTION: When using POP3, does the setting on my SMTP need a special setting on Thunderbird?.

NOTE: I am complying with "Rogers With Shaw" passing the buck to the Email Client (Thunderbird) by asking here - "Could It Be The Email Client'! And my answer is 'No', because Thunderbird works perfectly with 54 other Email accounts.

Thank for reading this, and for any input you may add, ~r

P.S., I'd like to see a upgrade to this input form that allows us to Preview out Post And, when I started this Post, it alerady had a image from a previous Post

I have 2 accounts. One account is for my normal email address, which contains my usual "Name+Surname@gmail.com The second account is for a fake name (as used on this forum): oldgrantonian@gmail.com

In Thunderbird, my normal email address works fine.

But the last email in my fake email account was on 16/02/2026. I can't send emails from the fake account.

The online version (mail.google.com) is fully up-to-date. I can send and receive emails in both accounts.

I would be grateful for any advice on how to restart the fake account.

Thanks

Thunderbird version 148.0.1 will not send outbound emails since updated to OAuth2. Error message is Unable to Authentic Outgoing server (SMTP) Email account will allow inbound mail , but will not send mail. Have worked through all published troubleshooting steps. Extremely frustrating!

*Fantasia I & II* Georg Philipp Telemann (1681–1767)
         Telemann’s Fantasias capture the brilliance and balance of the
         Baroque era—each movement a miniature world of counterpoint,
         grace, and invention.
*Kleine Passacaglia *Michael Kuntz (1915–1992)
          A modern take on a timeless form, Kuntz’s piece builds lyric beauty
          over a gently repeating bass figure. (See insert for more)
*Fair Phyllis I Saw* John Farmer (1570–1601)

I send out golf group e-mails. I have myself (e-mail address) in the group, so it will also come back to me. The server keeps rejecting my group e-mails because it says my e-mail address is incorrect, I have checked it several times and it is correct. I even edited it to be sure. Why is the server still rejecting it?

Thanks for your time....Paul Smart psmart@triad.rr.com
