Error in Email templates

I have a problem with the e-mails sended from our website.
If someone receives an e-mail the email has no sender and there's an code above our templates.

Below the code that is above all the e-mails:
 MIME-Version: 1.0 From: =?UTF-8?B?VTJtZQ==?=

We use 7.0.9. I attached the file inc/utils.inc.php.
I was looking for a solution and founded some forums regarding the topic.
I've tryed some things that were said in the forums, but nothing worked.

Does someone have an idea how to solve it?
