I really don't understand why I can read a message if it's encrypted

emails in here with my own public key? All my contact's public keys are
imported and added to my key-ring. I'm just puzzled that I'm actually
able to read a text encrypted with someone else's key.
OK. The text of the message is not encrypted with a users key; the
text of the message is encrypted using a symmetric key - the key for
*that* method (the session key) is encrypted using public keys, and,
the important bit, there can be multiple public key encryptions in one
message. So for a command line example you can encrypt a file using
gpg -r ID1 -r ID2 -r ID3 -e <file>
Where one of those IDs is your own - hence you will be able to decrypt
the file because you will be able to decrypt the session key.
