Thunderbird for Android Community Forum

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!
