I´m really confused. The Mail I send myself received in normal (not encrypted) text. But the mail I sent to someone else couldn´t be read.
I think I talk with my friend first to find out, why he couldn´t read my mail.

any email leaving your machine can only be encrypted for an account for which a sec/pub key exists in GPG Keychain. So the behaviour you describe indeed sounds unexpected.
You could ask your friend to extract the received message as eml file, zip it and send it over to you. IF you want attach the message in question and we can take a closer look.
Please export the message in question, so that we can have a closer look. To export, simply select the message in Mail.app and press CMD + SHIFT + S, select "Raw Message Source" as type and save it. We won't of course be able to decrypt it, but it will help with analyzing and hopefully finding a solution for your problem.
Attach the resulting .eml file to this discussion by visiting it in your browser (email reply should work but sometimes attachments do not arrive).
