Signed e-mail from sender allows you to verify the authenticity of a message -- that the message is from the supposed sender and that it has not been tampered with during transit. Signed mail messages are designated with the signed mail icon.

Any problems with a signed message will be described in a Security Warning which may follow this one. If there are problems, you should consider that the message was tampered with or was not from the supposed sender.

You as Recipient can use sender digital signature to verify sender identity, and you can use sender public key to send you encrypted e-mail that only sender can read by using sender private key.  You can use senders public keys to encrypt the messages. When a recipient gets an encrypted message, his or her private key is used to decrypt the message for reading.
