Thunderbird Community Forum

Hi Support, A customer uses Thunderbird as their main mail platform but suddenly cannot send or receive messages. error message as follows: Sending message failed. The message could not be sent because the connection to the SMTP server timed out. Try again. we get this message directly when we click send (1ms)

Now we checked our Mail Server, connection is up also TLS to port 587 works fine but the client can not establish a connection... it worked a few days ago tho. We also tried to reinstall Thunderbird, new profiles and also tried debugging but we could not find the mistake.

BR, Jakob Jauk

Hallo und guten Tag,

ich habe für Windows [PC] und Android [Pixel 8pro] jeweils die beiden aktuellsten Versionen von 'Thunderbird x64'und 'Thunderbird: Free Your Inbox' installiert und eingerichtet. Es sind zwei E-Mail-Konten mit jeweils einer Alias-Adresse eingerichtet, alles unter GMX.NET , IMAP+SMTP sind ebenfalls aktiviert [IMAP port993 und SMTP port465]. Leider bekomme ich es nicht so eingerichtet, daß Mails wenn sie am PC oder am Pixel empfangen und verschoben oder gelöscht oder als Spam markiert sind, daß dieses dann auch am jeweils anderen Endgerät so erscheint. Es werden immer wieder alle Mails neu als eingegangene Nachrichten gezeigt und ich muß dann am jeweils anderen Endgerät die gleichen Aktionen vornehmen.

Wo liegt der Fehler, was muß ich tun um das Problem zu beheben.

Hello:

Using Thunderbird for years. But please, for the love of God, someone tell me *why* Global Filters / Unified Inbox filters are not allowed? I've got 10-15 accounts, and I'm forced to refine/recreate my rules for each account?

Why? Why? Why? Why?

This is not a small thing, yet seems like such a common request. Please make this change/addition!

Thank you.

Windows 11 Thunderbird 128.5.0esr (64-bit)

I compact JUNK by right click "Empty Junk" / "Compact"

I compact TRASH by right click "Empty Trash"

File "Compact Folders"

This process used to show me how much space I am saving - I do not see this number anymore.

I am trying to setup an email account through Spectrum. My user name and password are correct, so I think the problem is in the server settings. Thunderbird has the settings as "mobile.charter.net". I have checked with Spectrum and this is correct. But Thunderbird says that something is still incorrect. Any advice on what I should do?

Hello, I downloaded Thunderbird in order to clean up storage on gmail account. Mainly, I wanted to delete files but keep the messages, a feature I thought Thunderbird provides. I deleted the files but they still appear on my gmail account and space size hasn't changed. I double checked the settings on both Thunderbird and gmail, as well as read and followed posts here, but it still doesn't work. I'm wondering whether I'm missing something... Any idea?

The spam people say to "limit outbound port 25 to mail servers". I have a profile listed on the webpage called "Outgoing Server SMTP Settings" from long ago .... This is the one (I have a few profiles) that is designed (Default)

Server: shawmail.vc.shawcable.net Port: 25 (default 587) Connection security - none

All my other profiles use: Server: smtp.shaw.ca Port: 587 (default 587) Security: STARTTLS

Q: Might this be the problem? Can I simply delete this profile - even if it is the designed 'Default'.

Hi, I download some e-mails. After checking the emails, I want all of them to be deleted from thunderbird but... ...I want only specified emails deleted from server.

In Mac's "Mail" program, there was a special window, where I could see all e-mails on server and just select which I want to remove from server.

In old Outlook, I've used "Rules". There I could set the parameters for specified e-mails and then tell outlook to "leave that message on server" or "Don't download that message from server".

How to do it in Thunderbird?

Hello, I am planning to do a fresh Linux install and in this context I also want to setup Thunderbird completely new, starting with the default settings. However, there are two things I would like to backup and restore (export and import).

1. The information which emails I have explicitly labelled as "Junk"/"No junk"
2. The information from which domains I allow loading remote content

I think this makes a lot of sense because I can setup my accounts easily and the mails, addresses and calendars will be synced from the cloud, and view configuration is no big deal either. Only that kind of "user data" that was gathered over several years is something I want to hold on to, and be able to continue to use. Is this possible somehow? I am not afraid, e.g., to manually copy individual files from the profile folder, if that data is stored cleanly separated somewhere. Kind regards, Chris

Hi I am syncing contacts between iCloud and Thunderbird and in most aspects it’s flawless. However when I change or create a contact in Thunderbird there seem to be a problem in character encoding. When I view the contact in iCloud the swedish characters åäö are replaced with som random strings. The other way around works as it should.

Does anyone recognize the problem and perhaps have a solution? Thanks.

Being fairly new to Thunderbird I'm still exploring the possibilities. I know I can display only unread messages in a particular folder by using the Quick Filter / Show only... option, but is it possible to set up a more direct method which requires only one click and is permanently displayed as an option?

Many thanks.

I would link to move my profile directory to a new location --- it seems that the best place for it would be a folder in my dropbox directory --- is this possible --- the best solution would be able to install thunderbird in dropbox so that any one of my computers can run thunderbird

Even though I'm logged in on TB with my Mozilla pw, TB will not reveal my passwords in TB settings. I use @hotmail.com and there appears to be a problem with pop3 server, Microsoft and TB. I get a authentication failure and according to FAQs I need to delete my pw in TB and enter a new one. But can't get there to delete.

Cannot connect Thunderbird on Win11 to my email account on mobile.charter.net. TBird recognizes mobile.charter.net and returns the configuration but subsequent login fails and is presenting mail.twc.net on the login screen. Outlook will connect using mail.twc.net. Any ideas?

Hi I have been at this for almost 2 days and have accomplished nothing. I am trying to get Thunderbird calendar and Zoho calendar to sync.

Everything is fine on Zoho but I can't find anything about syncing for Thunderbird. I am looking for CalDAV but it doesn't exist for my calendars.

If someone can help me I would be really thankful.

Thanks Norma C.

I am an longtime user but not a freak in using the system. I have the feeling that ISPs have difficulty in implementing good standards, but Thunderbird as well. I had a sequence of issues and failures and had to repair them by continuously changing settings and now it becomes virtually inoperable. I do not want to spend time in solving all these issues, if expert fora suggests pieces of python code as solution I have to conclude that the system does not work any more. One other problem TB changes apparently so much its own menu structure that that is also not working any more. And solutions given cannot be implemented. Sorry to say, this is immature freaky programming, you need some serious system engineers and managers to repair the chaos. Google and ISPs will anyhow continue with their own interest so Thunderbird should be robust against the outside inconsistencies. My complaint is both for the calender as the mail handling. Sorry to say, I am willing to pay that you could hire good programmers, but the volunteers with proper guiding are possibly better qualified. I hope you can solve the issues - changing fully to another environment implies reorganising my work environment.

Hoping you can recover, success, Lars Venema
