Thunderbird برای Android اجتماع انجمن

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

Functionality and usability issue: I use the Thunderbird for Android app as an adjunct to my desktop installation. Recently I had occasion to reply to an email in Android to one "to" recipient and needed to add two "cc" recipients, but found no way to add the cc recipients without deleting the existing cc recipients and having to input the entire (dynamic) group again, but then was also stymied by that. How best to handle this issue?

Other than that issue, the lack of desktop contacts synching, and the lack of spam filtering, Thunderbird for Android has been a huge help, so thanks to the developers for their dedication and hard work.

My email provider sometimes fails to send mail, so I find the mail that didn't send in the sending box (发件箱; I don't know the name in English), use the "edit as new mail" option in the mail 3-dot menu (there's a pencil icon on the top of the screen, but it has no reaction) and tap send button again. I find that every time I do this, the mail's sender identity is reset to the default identity.

I know my Thunderbird version is not latest and is beta, but I'm hesitant about updating. Is it a bug or designed behavior?

Steps to reproduce: 1. Turn off your device's network. 2. Compose and send a mail with an identity that's not the default. 3. Find the mail in the sending box, and choose "edit as new mail". 4. Hit send button. 5. View mail in sending box, it now uses the default identity.

Pixel 8a, 256GB/120GB free, Android 16, Thunderbird v16.1 Thunderbird stopped sending and receiving emails after several months. My storage is not full. I also deleted messages to be sure. I checked my android settings as indictated in the troubleshooting guides and have been unable to resolve problem. I have it set to automatically download emails. Manually checking emails by using the "refresh" button does not work either.

Hello

I have used K9 mailer for perhaps 5 years quite happily - this is my first question please.

In general I use "unified inbox" and sort the messages by "Date". This shows almost all messages sorted by the date/time they were sent, which is what I want. I often turn my tablet off for hours or days and then back on, so arrival time is delayed, but date/time sent is not.

My ReoLink cameras are configured to email me images under certain conditions. these messages always sort to the top, even though they were dated some time back. For example I turned on my tablet today (Monday) for the first time since Saturday, and received much mail. the ReoLink messages sorted right at the top. If I look at "show headers", at the end of the "received" field, it shows the correct original date of saturday morning. but the date/time at the far right of the "unified inbox" display shows the time at which I turned the tablet on and the message was received - only for this message, not for any others.

I am suspecting this may be a reolink problem, but not exactly sure what to tell them.

thanks for the help

I currently have Thunderbird installed on both my android and desktop (W11). My android inbox does not mirror my desktop. For example, desktop inbox shows many more emails than the android inbox. The ones that are in both are the same. Why doesn't the android inbox mirror the desktop version?

Additionally, I used receive a ton of junk mail when using Edison mail. Now I receive very little. Sounds like a good thing but occasionally one gets flagged as span and it isn't. They continue to show up in the Edison mail spam folder but not in Thunderbird.

I was hoping to drop Edison mail and use Thunderbird exclusively, but I need the confidence before doing so.
