Mam problem z kontem e-mail. Dotyczy on konta obsługi klienta sklepu internetowego. Od kilku dni maile z Amazon, Allegro, Emag itp w ogóle nie dochodzą. Nie wiem co jest tego powodem, nic w ustawieniach nie było zmieniane, stało się to z dnia na dzień. Jak mogę to naprawić?

Hello,

All my outgoing messages are bouncing back to me, no matter who I send or reply to, just from one of my email addresses: heidi@benvenutotravel.com

So I cannot reply to anyone nor send, although it shows copies in my sent folder???

When trying to retried incoming messages, I keep getting popup that ask for my password. I tried to use the hidden password in the app, which till now has always worked, but get the following message:

"Sending of password for user (parrotdise13@att.net) did not succeed. Mail Server inbound.att.net responded [SYS/TEMP] server error - please try again later."

I have browser access to my att/yahoo parrotdise13@att.net account after changing my password. But entering the new password in the above mentioned popup produces same result.

Thanks, John B.

Overnight, I suddenly cannot send emails. I keep getting an error code AUP #OUT-1500 that says: "The email address you are sending as must match the email address you used to auth. " But I have changed nothing. Everything worked fine Thursday when I went to bed; got up Friday unable to send. I can receive all day. And I can send using my provider's website, but I'd rather use Thunderbird as usual. What the heck just happened? None of the Support suggestions work. Thanks for any wisdom you can impart!

Hi I am getting on a daily basis Thunderbird Not Responding, so I have to start Task Manager to close the program and the open it up again. I like this program but this issue is now on a daily basis and has been like this for a couple of weeks now. Kind regards Jim M

I have tried multiple times to add an email account to thunderbird in windows but I keep getting the error, "Unable to log in at server...". I know the details are correct as I'm copying and pasting them from my password manager so I'm not sure what the problem is.

I have 2 windows 10 computers both with Thunderbird. One computer never has trouble with getting emails. The other shows every day "Login to server mail.hoster905.com with username cnc@lcgnm.com failed" I have reset this one password at the server, entered the new password in Thunderbird and can the get mail. That day only. Next day same problem.

Hello We are trying to set up an email client Mozilla Thunderbird, but nothing works, because the email client does not have enough fields that are specified by the provider, here is a letter from them:

Hello,

Your SparkPost account is configured correctly. I recommend contacting Mozilla Thunderbird support to see where you can enter the required fields in their SMTP client to connect to SparkPost. You can see the full client configuration steps here: https://developers.sparkpost.com/api/smtp/

They should be able to prove the steps to get these settings configured in their SMTP client.

Please let me know if you have any questions; I will gladly help!

On 5th June I received the following message when I opened up my email.

Warning: Potential Security Risk Ahead. Thunderbird detected a potential security threat and did not continue to live.thunderbird.net If you visit this site attackers could try to steal information like your passwords, emails or credit card details.

I have not received any emails since then. Nor able to send any. I can receive and send my emails through my Mail provider- Telstra Bigpond and also receive and send on my Apple iPad and Phone. I have tried turning the computer on and off but this does not help although I am no longer receiving the warning message. Hope you can help fix this. Regards Dawn Howell

I keep getting the following mesage, this has started all of a sudden, computer did a windows 11 upodate yesterday.

Sending of the message failed. An error occurred while sending mail. The mail server responded: Sender Policy - Relay Denied 211.30.49.152 authenticated connections ONLY. OB303 e{391cd896-4e9f-4d6a-9932-850a9ace859b}. Please verify that your email address is correct in your account settings and try again.

For the last 2 or 3 days I have been receiving the above message when accessing emails. I have experienced this problem occasionally in the past and for a day at most, the problem usually associated with virginmedia. However this is now proving to be disruptive and I don't where the problem lies, with Thunderbird or Virgin. None of my settings etc. have been changed and I can access everything if I go directly to the virginmedia website but the handling of the emails is cumbersome. Any ideas?

Hi all,

Sorry for asking again, but after reading all the posts here the problem is still occurring.

When I launch Thunderbird, I'm asked for new data (Account Setup), like there is no profile available.

The application seems unable to locate or recognize my existing profile, but the profilefolder exists and its almost 90Gb of data. Should I complete Account Setup windows with my data?

Please help me! Tried with thunderbird -p command to repair or select another profile but with no success !

- installs.ini Default=Profiles/xxx.default Locked=1

- profiles.ini

Default=Profiles/xxx.default Locked=1 [Profile0] Name=default IsRelative=1 Path=Profiles/xxx.default Default=1 [General] StartWithLastProfile=1 Version=2

User Agent Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:115.0) Gecko/20100101 Thunderbird/115.11.1 OS Windows_NT 10.0 19045

Thank you !

I have tried nearly everything on all the forums and help sites to no avail. I still get the error message that my message cannot be sent. Most of the time I get the server response as [C20]: message blocked. I have triple-checked my SMTP server settings and password, uninstalled TB and re-installed. TB seems to have recently changed the profile in use, so it no longer has all the files in Mail\Local Folders it used to have. I'm thinking I need to create a new profile but I don't know how to do that.

Hello,

My boss, (small family business) insists on using Thunderbird for the business. He sends and receives hundreds of emails every day. Often times has 20+ email tabs open at the same time. It's become such a problem that I have purchase larger SSD drive because he was always running out of storage space on his PC. His Thunderbird file is currently over 12 gig.

The main issue is: He will have several emails open and will start to reply to a customer. When he hits reply, the body of the email references data from an really OLD previous email that was either archived or deleted. Most of the time these are emails that were previously deleted. Then he goes back to his Inbox to try to find the original message and it cannot be found and is missing. He then finds the original email on his iPhone Inbox (Same Email Account - IMAPED to his phone) then forwards it to himself, in order to obtain the original contents of the message again. Sometimes the reply box has data from multiple old emails! It's hard to explain.

This goes on and on and he's driving me nuts, as I'm the local "Mr. IT Fix it." for the company. Although, I have no formal degree or training in such things. My background is in Accounting. LOL

From reading other forums, this appears to be either an IMAP Indexing or Email Deletion Retention policy issue? But it's just really beyond me!

Both myself and a family friend who actually has IT support exp. have told him to stop using Thunderbird for Enterprise use, and migrate to a more appropriate application. But he doesn't want to have to learn anything new or complicated.

Any thoughts, suggestions, other places where I can find a possible solution?

One other thought: This issue does goes go away (albeit Temporary) when I clear his system cache and Force ALL Thunderbird folders to Compact. Thank you!

If the above data is too vague, I can try to provide steps to replicate and screenshots on the next time this happens. Which is often. However, it is almost impossible to replicate on demand.

Additionally - I've read in other forums of similar issues where they were related to indexing and IMAP syncing across multiple devices. One person commented - that it was a deletion retention failure policy within Thunderbird. Something to the effect of, Thunderbird never really deletes emails when you press delete on the desktop application. The email is marked for deletion but all of the email headers and data is still stored in the active cache, or something like that. - And apparently, there is a lag in time that the server or servers update a deletion request if the email is deleted from another app. His primary email host is Comcast.net. So, he's using Comcast Webmail, Thunderbird Desktop, and iPhone 13 mail app. via IMAP, all for the same account that has about 10+gig of stored emails. Oh, he currently has threads turned off by request. Storage cache is currently set to 650mb.

Any help, suggestions or solutions are greatly appreciated. If you have any areas that need clarifying, I would be happy to take screen shots or provide additional data in order to find a valid resolution, as he's not interested in migrating to Outlook or any other Enterprise application.

Thank you!

Witam, w ostatnim czasie mieliśmy jakiś spam na naszą pocztę i dostaliśmy blokadę, zależy nam na zdjęciu jej ponieważ jest to e-mail firmowy i jest nam potrzebny. Proszę o informację co mamy zrobić aby zdjęto blokadę. Pozdrawiam

Hello everyone. I have just installed version 115.11.1 (64 bits) on my PC. The fonts of the incoming mail messages display strangely and change when I move the mouse over them. Attached are two screenshots of the same messages at two different times: https://mega.nz/file/vZtlBCSa#Hi_C1bjz4NNvG5WPfqSam1eefv7BHvF4bGv6VWNDZ8g

The rest of the programs and windows display normally. The problem only exists in Thunderbird windows. Does anyone have any idea what the problem is? Could a graphics card at the end of its life be at the root of the problem? Thanks.

Witam, Mam problem z wysyłaniem wiadomości przez Thunderbird. Przy próbie wysłania wyskakuje takowy komunikat. Nie rozumiem z jakiego powodu mogłem dostać blokadę, ponieważ nie wysyłam aż tylu wiadomości, żeby można je było uznać za spam. Co mogę zrobić w takiej sytuacji, aby jak najszybciej odblokować swoje konto? Proszę o jak najszybszą pomoc, możliwość wysyłania wiadomości jest mi bardzo potrzebna. Pozdrawiam.
