Not Saving Sent Messages in Sent Folder on Roundcube

[J-J-Chiarella]

• I have used the search function to see if someone else has already submitted the same bug report.
• I will describe the problem with as much detail as possible.

App

Thunderbird for Android

App version

14.0

Where did you get the app from?

Google Play

Android version

Samsung One UI Core 4.1 (Android 12 customization)

Device model

Samsung Galaxy A01 (SM-A015M)

Steps to reproduce

1. Register on Thunderbird an email account for a service that uses Roundcube, such as Porkbun (a registrar and hosting company in Oregon).
2. Write a new message or forward a message or reply to a message, and then click Send.
3. See that message did get sent but was not saved in the Sent folder (or the Outbox, for that matter).

Expected behavior

The user expects a sent email to be saved in the Sent folder so that it is saved and also viewable on desktop Thuderbird, Android Thunderbird, and thevwebmail interface.

Actual behavior

Message that was sent does not get saved to the Sent folder, and hence is not viewable in any form after the sending event.

This issue does not manifest on Thunderbird for desktop or on the webmail interface for Roundcube. Account uses a normal password for IMAP and for SMTP, and each connects with TLS, not OAuth or STARTTLS.

Roundcube 1.16.11 (released 2025)

A couple of suggested settings i'd recommend checking.

1. Confirm "Sent Folder" has a folder name assigned under settings > account > folders.
2. Confirm "Upload sent messages" is ticked under settings > account > sending mail.

The suggestion to check the assigned folders seemed to work.

At the very least, I have brought attention to something that is not automatic. I have had this folder assignment be automatic for every other account that I have ever set up with this program, even ones that did not have a famous Gmail or whatever associated.

Why my Roundcube account, and no other got this treatment, I don’t know.

Thank you for your time.
