Thunderbird för Android gemenskapsforum

Hi to everyone. I'm hoping someone can help. See attached picture. I have been getting this notification now and then for a few weeks now. It's getting annoying. Every time this happens, I have to manually verify my sign-in information, and it goes through without any issues. Everything stays OK for a week's time or whatever, and then, boom, I get this again. Is anyone else having this problem? Are the Thunderbird developers aware of this problem? Is there a fix I can try to stop this from happening again? Thank you very much.

Witam, - czy Thunderbird mobile możne synchronizować wiadomości mail wychodzące z telefonu i z komputera na obydwu urządzeniach? Synchronizacja wiadomości wychodzących telefon i PC. Wysyłając z telefonu mam je na PC i na odwrót. - czy Thunderbird mobile może synchronizować podpis z grafika z maila na komputerze?

I just installed Thunderbird for Android on my Pixel phone for the first time. I have used Thunderbird on my desktop PC for many years, so I am very familiar with Thunderbird in general. I used the "Export for Mobile" feature on my desktop installation, to import my account settings into the Android installation.

For the most part, Thunderbird for Android works great, as I would have expected. However I am seeing a problem which appears (to me) to be a bug. When I compose and send an email on my phone, and then look in the "Sent" folder on the phone, the email that I just sent shows up there. But only on the phone. If I open Thunderbird on my desktop PC and look at the Sent folder there, the email that I sent from the phone is not there. Apparently, it only gets placed in the phone's Sent folder, but it does not get copied to the email server.

A few other details: -- I use Thunderbird on 2 different desktop systems, a PC and a Mac. When I send email from either of those, that email DOES show up in the Sent folder on the other system. Emails that are sent from either desktop system also show up in my phone's Sent folder. So I know that the Thunderbird desktop application does upload the message to the email server's Sent folder correctly. But Thunderbird for Android does not upload its sent emails.

-- I don't know if it matters, but my email server is Microsoft 365, hosted by GoDaddy.

-- As far as I can tell, the most obvious setting for this is the "Upload sent messages" checkbox, which can be found in the "Sending mail" section of "Account settings" in the Thunderbird Android settings. This checkbox IS IN FACT turned on. I could not find any other settings which could possibly affect the copying of sent messages up to the email server's folders.

Is this a bug? Any ideas what might be causing this? Thanks for any help.

Hi, I'm trying to find out where (in the code) the app checks the server certificate. I consider myself a programmer (thanks Edsger!) but after some browsing I did not find the way in the repo.

The issue is that in my experience, every time the server cert is changed (Imaps, LetsEncrypt) k9 asks me to validate the new cert. And I have 2 things I want to check: -Another user says he is also using K9 and he's never presented with a cert issue on change -I want to see the possibility of directly accepting the new cert iif stored cert is about to expire, new cert comes from the same authority (root CA) and PK is the same.

Any help in this regard is appreciated! -Carlos

Hello, here’s the problem: I had / have 3 GMX mailboxes in Thunderbird on my PC. After I installed Thunderbird Mobile and spent several hours with it, I deleted all the mailboxes to import them again. Apparently, this also deleted all the mailboxes on GMX, as they are no longer visible there. I also can’t create new ones there, as the old ones seem to still be somewhere in the Background. In Thunderbird Mobile, I restored the mailboxes via import, but they are completely empty! Thunderbird Mobile has no connection to GMX. What can I do? I go to bed...

My email provider appears to require a unique password for every device (I think is locked to the MAC address).

I have a new version installed from the android play store yesterday.

The QR code method of creating a account from my Ubuntu Thunderbird app does not work. Importing a working account from google does not make any sense on a new device (the MAC address for the original device will be different)

How do I manually edit of enter the configuration so that i can use my android phone as an email client?

Hi all,

I have installed Thunderbird Android and correctly set an IMPA account. It is not a "provider" email, it is my own email using my domain.

I am able to receive emails, no problem there, but I am not able to send emails. After I tap "send", emails are moved to the "sent" folder, but they are never delivered (they don't go to spam). I have also checked the settings with my provider, that hosts my email, all is correct.

Additional context. - If I send an email to myself (same from/to email address), that is sent. - I have tried K-9 with the same settings, it doesn't work neither. - I have FairEmail with the exact same settings, and YES emails are correctly delivered using FairEmail. - Thunderbird app version: 8.2 - Device: a Redmi Note 13 Pro 5G, with Xiaomi HyperOS 2.0.4.0

Thanks

Last week MailChannels began blocking ALL emails that I send from Thunderbird for Android.

Prior to this I had no problems sending from Thunderbird for Android, but MailChannels claim the issue is that Thunderbird is creating malformed headers or message IDs.

Other clients for Android are able to send mail without problems. Thunderbird for Windows is able to send mail without problems.

Looking at the source of the headers in mail that fails and comparing with mail that is not blocked, the only differences I can see are that Thunderbird for Android is the only client creating messages IDs where the UUID part of the ID is capitalised - other clients use lower-case letters in the UUID. As far as I can tell either is legitimate.

The only other difference being the inclusion of the User-Agemt identifying the client as "Thunderbird for Android"..

The error message in MailChannels' bounce is as follows:

550 5.7.1 [CS] Message blocked. If this is a false positive, please report this to your hosting service provider.

The reason for rejection given on the linked MailChannels page is that the message has been identified as spam content.

I have contacted my hosting provider and after a lot of emails exchange (using Thunderbird for Windows!) they have simply said that the problem is with Thunderbird and that I should change my email client - no explanation of what they think is wrong with the headers!

Is there a way to enable sync for all folders by default?

I have my mail server set up to put messages to the address mail+x@... In the folder "x" and I use different addresses for every service I sign up to to avoid spam. This has all worked very well with k9 until recently - new emails were automatically shown, even if they were in new folders. But since a few days this doesn't work anymore, only the Inbox is synced, and I have discovered that there's an option to enable sync for every folder individually, which doesn't work for me, as I need the app to sync new folders (and I have too many folders already for it not to be annoying to enable everything manually).

Thanks in advance!

I installed Thunderbird for Android today on my Moto g stylus. I used the QR code to import the settings from Thunderbird on my Windows 10 laptop. In general, things seem to be working, but outgoing messages are not being copied to the "sent" folder. I can see older "sent" messages that were sent from my Windows 10 Thunderbird, but no sent messages that originated from my phone. I have an IMAP mail server.

Would like to remove the long folder names and only show the last sub folder name. For example instead of seeing INBOX.travel.Uk - only UK would be visible as part of the folder tree
