Mailbox — questions

Answers built from our own checks of this server.

Why is there no uptime for Mailbox?

Mailbox runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.

Is Mailbox open source?

Yes — it is published under the WTFPL licence, written in Python and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
