- How much disk space (quota) will be available to my mailbox?
When you sign up, 25 Megabytes are assigned to your mailbox. If you make a donation to Torbox we will increase the quota to over a Gigabyte. Just contact us! (postmaster @ torbox3uiot6wchz.onion).
- Is my email secure?
This is a standard email system. The communications between you and the server, and the server-to-server MTA transport, are encrypted as they are established within TOR network, and the email data storage is also encrypted because the server uses encrypted partitions. Still you must use personal encryption methods like GPG. We encourage you to encrypt your email and not to store sensible data in the mailbox.
- I lost my password. How can I recover the access to my account?
If you previously added your PGP public key to your account, we will send you a token encrypted with it. If you answer us with the correct token we will reset the password for your account. Otherwise, if you did not add any PGP public key to your account there will not be any way to prove you are the owner, so we will not reset the password for you.
