Thunderbird for Android Community Forum

Yesterday I integrated my email into the desktop using my email as the user and my password. I also downloaded the mobile app for Thunderbird on my Android upon which I was not able to use either the user or the password to log on. The response was simply I do not have an account. Trying to mitigate this. Thank you - Brian

I'm having issues sending and outbound email and I'm not getting any error messages from the client. I have confirmed that the email server settings are correct. I am unfortunately unable to find a log or error console on the app to further trouble shoot all I get is a notification of "unable to send mail" with no error codes.

Hi, i have been using Thunderbird on Android with Talkback since I am blind. The app is excellent, but I found a bug. When I use the search function for example filtering the emails for a certain expression, the result list is not accessible with Talkback. Phone Oneplus 12R, firmware android are the lateAst. Please, identify the issue and fix it.

The app is perfect for me, except the text in the inbox page is so small 😭

Can this be changed? Can we get an option for it in settings?

It would be wonderful to have font size and style options.

Thanks

I have a couple of folders I use a lot in my email account, and I regularly need to dig into them. The desktop lets a user favorite a folder to its sidebar for fast access. Can the Android app do similar?

Device: Google Pixel 10 XL, Android 17 App: Thunderbird Beta for Android 24.0b2 Desktop: Thunderbird 157.0.1 (64-bit, release channel)

I imported my eight accounts from Thunderbird Desktop using Tools > Export for Mobile and scanned the QR codes in the beta app. The scan worked and the accounts imported, but setup had several confusing steps:

1. For each Google account, an Android screen appeared saying "select which apps to restore", as if I were setting up a new phone. I didn't know what to select, so I skipped it each time. 2. After skipping, a blank accounts.google.com page appeared. I never saw a normal Google permission screen. 3. After the last account, the app showed a screen asking me to enter an email address and would not let me continue. When I pressed back and reopened the app, all accounts were there and receiving mail, so it seems to be a leftover add-account prompt after a successful import.

For comparison, with the stable app, the same accounts imported into K-9 Mail with the same kind of QR code with no restore-apps screen, no blank page, and no extra prompt. Gmail accounts signed in normally.

The accounts work, so this is about confusing setup steps rather than lost data.

Expected: Google accounts sign in through the normal permission flow without the Android restore-apps screen, and the app goes to the inbox after import without asking for another account.

hello, having trouble ading matthew714.com to my aol account on a samsung android phone...it is asking for a password...it won't take the p/w I use for my thankslord4me@aol.com account

I hope an email translation feature can be added to the application, similar to Gmail's, making it more convenient to translate the content of emails written in foreign languages.

When I access my email on my computer using Thunderbird, I have it set to downloaded the emails locally and remove from the server. Starting today, WHEN I access my email using Thunderbird in my phone, all the messages are still there, and I have to manually delete them, and they still stay on my computer email app. I need Thunderbird on Android to start removing them again once I clear the server.

Bonjour, Lorsque je mets un courriel en indésible, lors d'un nouvel envoi je le rtrouve dans ma boite de reception. Il ne va pas directement dans le dossier indésirable (ou junk) Merci

Dear Thunderbird Team,

I am writing to report a privacy concern and request a feature that would allow users to hide their real IP address when sending emails through SMTP.

When I send an email using Thunderbird with a standard SMTP account (e.g., QQ Mail, Gmail, Outlook), the receiving mail server adds a `Received` header that contains my real public IP address. For example:

```text Received: from ehlo.thunderbird.net ([2409:8a20:1843:3590:xxxx:xxxx:xxxx:cde2]) by newxmesmtplogicsvrszc50-0.qq.com (NewEsmtp) with SMTP id B2A37C97; Fri, 25 Sep 2026 12:44:42 +0800 ```

In this case, `[2409:8a20:1843:3590:xxxx:xxxx:xxxx:cde2]` is my real public IPv6 address. Any recipient who views the full email headers can see my IP address and infer my network location and ISP. This is a significant privacy leak, especially for users who need to protect their identity or location.

Currently, Thunderbird does not provide an easy way to prevent this. Even if I change the `EHLO` argument, the receiving server still records the IP address of my connection. The only practical workaround is to manually set up a proxy or a mail relay outside the client, which is not user-friendly.

I would like to request the following:

1. Built-in proxy support – Allow users to send SMTP traffic through a SOCKS or HTTP proxy, so the receiving server sees the proxy’s IP instead of the user’s real IP. 2. Relay/anonymization option – Provide a simple way to configure an external SMTP relay that strips or replaces the original `Received` headers before forwarding. 3. Documentation or guidance – If a full feature is not feasible, at least provide official documentation on how to hide the sender’s IP using existing tools (e.g., Tor, VPN, or a custom relay). 4. Privacy setting – Consider adding a privacy option that warns users when their real IP will be exposed in outgoing SMTP headers.

Steps to reproduce:

1. Configure Thunderbird with a standard SMTP account (e.g., QQ Mail). 2. Send an email to any recipient. 3. Ask the recipient to view the full email headers. 4. Observe the `Received` header containing your real public IP address.

Expected behavior:

The client should offer a way to anonymize the sender’s IP address when sending via SMTP, either through a built-in proxy setting or by supporting an external relay that can strip identifying headers.

Actual behavior:

The client sends the email directly from the user’s device, and the receiving server records the real IP address in the `Received` header, which is then visible to all recipients.

I understand that SMTP servers often log source IPs for anti-spam purposes, and that the client cannot control what the server adds. However, by providing proxy or relay support, the client can give users a choice to protect their privacy.

Thank you for considering this request. I believe many privacy-conscious users would benefit from such a feature.

Sincerely, wyxtld
