Issue with hyperic emails

Hello,

We just migrated to version 5.0, since then the emails that are sent have this line in the very beginning "MIME-Version: 1.0 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: 7bit X-Priority: 1" because of this the html emails appear as plain text. This only happens with emails that hyperic sends, if I send emails from the command line or with another application on the same server that line does not appear.

Any ideas?

Regards.
