Q: Why is my notification email in garbled HTML code?

A: Outgoing email is sent out in text/plain, and thus you'll see the HTML code as-is
   if the email body is in HTML. This happens if you have $response or $description in
   the template and they have HTML content, as is the case if they are saved from email
   submission and the email has only the text/html, but no text/plain part.

   New versions of Bugzero have better handling of outgoing HTML emails, and this
   problem has gone away. The other option, probably even better, is to configure your
   mailbox to always have the text/plain part. For example, in Exchange 2010,

   Exchange server -->  Mailbox Features --> POP3 Properties, 
   and change from default "Best Body" to Text.
