Bug description

Hello Devs.

After updating to 30.0.0 sharing files via email does not work as it is supposed to I guess. There is no mail being sent to the sharee. So the one I try to share the files with is not getting notified. Nothing in the logs.
Email in general works. Invitations for talk go out.

Steps to reproduce

1. Share file via Email
2. Save
3. No email to the sharee

Expected behavior

Sharee gets notified.

The same here. But the function is essential for me (and probably for others too).

Yes its the only usecase for our company. Same problem here, just restored the old version from backup and waiting for the fix.

Lucky you. In our case, by the time I realized it, so much data had been changed that it no longer made sense to restore the backups for a downgrade. Unfortunately, I now have to wait for the error to be rectified. However, I cannot understand why such an important function for a version release was not tested extensively. My OpenOffice connection also only works if I change the program code. After that, however, the mail app no longer works. None of the last releases have caused so much trouble.

Confirmed this is broken in 30.0.0. The [ Send Email ] button to test smtp works. However when you share a file by email address, the outside user never gets email. Confirmed that email is bouncing correctly to this same smtp host at the operating system level.

Here is my log (level 0):

"Share notification not sent because mailsend is false."

Hello Devs!

Is there maybe a patch or workaround we can try until this is fixed?

cheers!

[Bad-and-Mad]

Dear developers, is there anyone who can tell us how to set mailsend to true? There must be a way in the code to influence this logical state, as it is also queried and evaluated by the sharing api.

This issue deserves urgent attention. The email sharing function is a critical feature of Nextcloud, and we are now two weeks into a stable release with this functionality broken.

I've observed an additional detail that may be helpful for troubleshooting:
When creating a new share, no email is sent to the recipient. However, if we edit an existing share (e.g., change the password or add a comment), emails are successfully sent.

This behavior suggests that the email sending mechanism itself is working, but there's a specific issue with the initial share creation process. Can the development team please investigate this discrepancy?

Given the importance of this feature for many users and organizations, we urgently need an update on the status of this bug and an estimated timeline for a fix. In the meantime, are there any workarounds that can be implemented to restore this functionality? If there's a specific commit that introduced this issue, would it be possible to temporarily revert that commit as a quick fix until a proper solution is developed?
