The problem occurs when using Zeta Components' ezcMailComposer to send e-mails that contain a "To" field with a long name (used 80-100 characters) AND non-standard Norwegian characters such as "ÆØÅæøÅ". When that happens, you will get an email where the email headers are corrupted.

Steps to reproduce:

• Configure PHP to use a suitable e-mail technology. For testing purposes, sendmail was enough, had no need to configure SMTP;
• Copy the attached "testmail.php" script to eZ Publish's root;
• Run script from command line like this:

php testmail.php <test@email.com>

The e-mail is sent with corrupted headers. Please refer to the attached "zeta_components_response_headers_nor_characters.txt" file. You will notice that there are double linebreaks after the Date header, which causes the problem.
