I have today for the first time successfully installed Postfix and Dovecot and I can send and receive emails But I have two minor issues:

1. When I use Danish letters Æ, Ø and Å in emails, they are transformed into something that looks arabic!

2. My sender email adresss is myname@myservername.mydoamin.dk. How do I get rid of the "servername" part?

Any quick tips regarding these issues?

Thanks a lot!
