Mozilla Thunderbird allows for granular control over where your outgoing correspondence is stored. By default, it creates a local “Sent” folder, but to ensure your sent history is visible on your phone and mybox webmail, you should manually map it to a folder on the server.
This configuration ensures that your sent items are synchronized across all devices using IMAP.

Step-by-Step Configuration
To designate the correct sent folder in Thunderbird:
- Open Mozilla Thunderbird.
- In the left-hand navigation pane, right-click on your email address.
- Select Settings from the context menu.
- In the account settings tab that opens, select Copies & Folders from the sidebar.
- Under the “When sending messages, automatically” section, ensure Place a copy in is checked.
- Select the radio button for “Other” and use the dropdown menu to navigate to:
[Your Account] -> [Sent folder on the server]
What to expect
Once you save these settings, any email sent from Thunderbird will be uploaded to the mybox server immediately. This makes the message available to any other mail client or web interface connected to that account.
Note: If you see multiple folders with similar names (e.g., “Sent” vs. “Sent Items”), choose the one that matches the folder used by your other devices to maintain a unified history.
Practical Implications
- Server-Side Storage: By selecting a folder under your email account name (rather than “Local Folders”), your sent mail counts toward your mybox storage quota but remains accessible from anywhere.
- Organization: Correct mapping prevents Thunderbird from creating redundant folders (like “Sent Messages” and “Sent”) on the server, which can lead to a fragmented conversation history.
- Offline Access: Even though the folder is on the server, Thunderbird keeps a local cache, allowing you to search your sent history while offline.
