Is the mail alias service private?
Generally yes, but not absolutely. The AMSAT.ORG system logs sender and receiver address and message length. The message content is stored briefly on the AMSAT.ORG system before being relayed to your mailbox. The system administrators generally do not look at specific messages, but reserve the right to do so when necessary. We take reasonable precautions to prevent others from having access to the system. We never publish or sell a list of mail aliases (though years ago we did make such a list freely available for the convenience of other amateurs). Anyone may check a specific callsign to see whether it corresponds to a mail alias (using the Mail Alias Lookup facility).
