I can no longer send messages through the email client on one of my accounts using Thunderbird, which no longer recognizes my internet service provider's password (but it does receive messages). Everything works fine with my other accounts.

Thank you for your help.

Recently I have noticed some changes in the way my Thunderbird downloads POP3 messages. Previously, it would be common to ask for new messages once a day and receive upwards of one hundred of them. But in the last month, this number has been limited to about 35 at a time. If I ask immediately again, I get about 35 more, and this pattern continues as long as there are messages in queue waiting to be downloaded. I am not sure if this is due to changes in gmail, where most of my received messages originate, or to changes in Thunderbird itself, or to some sort of third-party hack. Now that I have trained myself to keep on asking until there are no more messages coming down, this change does not cause me much difficulty, although initially it sometimes caused me to overlook messages because I failed to keep asking as long as I should have. Apart from that, it does not seem to be harmful as far as I can tell. I'd just like to know if other people have noticed anything similar, and if anyone knows what is causing it, and whether it has some hidden advantages over the way things used to work.

I am with Force9, part of plusnet. Since their migration to Greenby, I am not getting e-mails in Thunderbird. I've tried mucking about with settings, but I'm groping around in the dark. Anyone out there who can help?

I am unable to recieve mail on thunderbird for the last several days. I am receiving the message "Alert from account xxxx@comcast.net: Temporarily blacklisted IP Address - try again later (comcast is my mail provider) where is this message coming from and how do I clear it. I use a VPN and have shut that off but has not fixed the issue. I have the same VPN running on my Iphone and am able to still recieve messages via the Iphone mail client... Any thoughts?

Hello, I can receive email messages but unable to send them out. The error message I get follows:

The mail server responded,( bettyweber@shaw.ca sender) rejected AUP#POL. Verify your email address is correct in account settings.

What can I do to fix this in Thunderbird?

I checked with my service provider and I can receive and send messages through webmail but not Thunderbird.

Thanks. Betty

Over 4000 previously deleted emails suddenly started loading to my Inbox. I have tried to delete them but get a message - "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox". There appears to be plenty of disk space and as far as I'm aware the file system allows write privileges as I am Administrator. I have managed to delete the messages using Up Function+Delete, (which doesn't write to the Delete folder), and have cleared all from Webmail but still have the same problem. I am also unable to receive any new emails. The email is POP3 configured. I have ensured that my Thunderbird if up to date. I operate Windows 10.

Thunderbird shows the number of emails downloaded but I can not see them in my inbox, or anywhere else. Using Thunderbird 115.5.2 (64-bit) on an older iMac on OS 10.12. Email account is gmail, and using POP. I've tried 'repair folders" with no change. I've deleted old emails from the Gmail server. Would appreciate any help.

I have Mozilla Thunderbird installed, the Yandex mail instructions say - The server name is imap.yandex.ru and the server name is smtp.yandex.ru . with such constructions, the mail does not arrive. Mozilla uses ru - com instead by default and everything works, but it feels like it's wrong because everything slows down terribly. If I change to ru, the mail does not work. https://disk.yandex.ru/i/7V9_I1XwoBLPiQ

I received an e-mail containing an invitation. Inside the invitation, Thunderbird corrupted a URL (zoom link) by adding an extra "\", and corrupted the sender's e-mail address, by concatenating it with the sender's last name from the previous line. Has anyone else seen this? How can I prevent it from happening?

Screenshots of the invitation are attached, one copied from the message on the mail server (gmail viewed in Chrome), and the other showing how Thunderbird rendered it. It's drastically different in format, which would be fine, except the content has been changed as well. Note the extra "\" in the Zoom link in the Thunderbird version (verified incorrect) and the e-mail address Davidcdavid@FCNL.org, containing the extraneous characters "David"

Many thanks for help.

I am sending a message with Thunderbird through my email server Yahoo. The sending has worked flawlessly until yesterday afternoon; I am getting the following error.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.mail.yahoo.com timed out. Try again.

This works fine with Outlook but not Thunderbird since yesterday afternoon.

This is a new problem, and I don't know why - nothing has changed on the account. When trying to send an email, I get the message Sending of message failed. An error occurred while sending mail.The mail server responded Relay access denied. Authentication required. Please verify thst your email address is correct in your account settings, and try again. I have checked account settinga, and the address is correct. However, the 'from' address at the top of the email to be sent gives our names (Iain & Sue), the correct email address, then repeats the email address, then Cc Bcc. This does not seem right. Can you help, please? Iain Harrison

That's a weird one, but I did some testing, and I am sure it is some problem with my Thunderbird or configuration.

Here is what I do. I received an email. I reply to it. I see the reply in the Sent folder. Then I click on the reply and choose to reply to that (as a follow-up email). I verify the recipient is correct and send it. They received my email, but I can no longer find it in my Sent folder. It is nowhere to be found. Tested with another email client - everything works as expected.

Does anyone have a clue what I am doing wrong??

Hello,

let me tell you that I have a few hundred email filters defined, and they (almost all) work fine.

There are three filters that cause problems, and it looks like the problem sticks to the sender.

Let me expand: FAZ, REWE, and Campact cause problems. Two out of three emails from these senders can't be moved to the target folders. I get a pop-up messeage telling me that I have to repair the folder. I do so, and a few days later the same problem comes up. Just for these three senders.

I searched all folders for filters for these three and removed all filters I could find.

Then I created a new folder as a child to the inbox folder, and a new folder inside of this folder to hold emails from FAZ. I defined a new filter rule, as the old ones were removed. Worked for a few emails, and, voila, the message pop-up came again, telling me there are problems moving the email over to the (new) target folder.

Let me repeat: all other filters work fine, just emails from these three senders cause problems.

Any idea where I could have a look, a switch to check?

One last information/idea: all three have different email addresses they send from, I will check the ones that do not work, maybe there is a clue.

I am using POP3/SMTP, not IMAP.

Hoping for a tipp, a clue, an idea -

Thunderbird is not working with mitchells new version. I am getting a MAPI.Send() returned -2147467259. How do you correct this? Mitchell is saying it on your end.’ for ‘Thunderbird’

Not receiving email from certain "institutions;" seems OK from individuals, but can't be sure. Use Outlook address as main "give out" address. All mail is autoforwarded to a Gmail address where Tbird picks it up. Been happening for a while, but this is todays experience. Intermountain Healthcare (IHC) sent me an email with a verification code for my email address. Never arrived. Went to Outlook.live.com > not there. Went to Gmail.google.com > not there. Does this imply it's IHCs fault? REALLY having trouble resolving this. Suspected it has happened with other "institutions" as well, as phone calls indicated emails had been sent. Have created "Message filter" that runs before spam classification that moves messages from IHC addresses to my inbox, but doesn't seem to help. Any help appreciated.

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
