No. You can only send and receive email to/from other users within TorBox service and the mail servers which relays email with us.
To know which email services you can send and receive email to/from, check the list of email services relay.

You have to add to your MTA a rule that all the email which destination is TorBox must be forwarded to torbox36ijlcevujx7mjb4oiusvwgvmue7jfn2cvutwa6kl6to3uyqad.onion and you must contact us (postmaster@torbox3uiot6wchz.onion) to add your domain in our MTA rules in order to correctly forward all the messages sent from TorBox to your domain.

No, not for the moment. Torbox will remain as stealth as it is but we do not stop adding new relays to other major email services through TOR.

Yes. You must use the following configuration:

SMTP: torbox36ijlcevujx7mjb4oiusvwgvmue7jfn2cvutwa6kl6to3uyqad.onion Port 25
IMAP: torbox36ijlcevujx7mjb4oiusvwgvmue7jfn2cvutwa6kl6to3uyqad.onion Port 143
POP3: torbox36ijlcevujx7mjb4oiusvwgvmue7jfn2cvutwa6kl6to3uyqad.onion Port 110

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).

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.

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.
