Quota limit still hardcoded to 50GB in Mailu 2024.06.54 - urgent need for larger mailbox

Author: skye20020Created Jul 11, 2026Updated Jul 11, 2026

Hi Mailu team,

I would like to report that the 50GB quota limitation in the admin UI is still present in Mailu 2024.06.54.

I found the existing issue #2998, but since it is still open, I wanted to confirm that this is still affecting current installations.

Environment: Mailu version: 2024.06.54 Deployment: Docker Compose

Problem: The admin UI does not allow setting mailbox or domain quotas above 50GB.

Even when: Domain maximum quota is set to "Unlimited" The server has enough storage available

the slider remains limited to 50GB.

The cause appears to be the hardcoded limit: max=50*10**9 in: mailu/ui/templates/domain/create.html mailu/ui/templates/user/create.html

This is currently blocking us from expanding an important production mailbox that requires more than 50GB storage. Could you please prioritize this issue or advise the recommended workaround for production environments?

A configurable quota maximum or a numeric input field instead of a fixed slider would solve this limitation.

Thank you for your work on Mailu.
