THE P2P MAIL OF PSIPPR
PSippr P2P Mail
E-mail that goes directly between your devices, end-to-end encrypted, with no SMTP or IMAP server in between. The PSippr node keeps mail for a recipient who is offline.
HOW IT WORKS
Mail from device to device
Direct deliveryWhen the recipient is online, the message goes straight to their device over an encrypted peer-to-peer connection.
Offline recipientsWhen they are offline, the encrypted message waits on the PSippr node for up to 30 days and is delivered when they come back.
End-to-end encryptedEvery message is encrypted for each device of the recipient and signed by the sender's device. The node sees only the two device ids, the size and the time.
Your addressAn address is the id of your device, or name@domain when the domain publishes a DNS record listing your devices.
All your devicesPhone and computer keep the same mail and the same state: read, starred, trash and deleted.
Spam limitsAt most 5 foreign addresses per message and 3 similar messages a day to a foreign recipient, checked by sender, recipient and node.

FROM WEBMAIL
Switching from webmail
Webmail keeps working. P2P mail is a separate, more private mailbox: install the app, add your account and give people your new address. P2P mail does not exchange messages with ordinary e-mail yet. webmail.psippr.cz
