Password Reset Notification in plain text and not HTML

Please assist,

I have a requirement to send the emails regarding password reset for access control in plain text instead of HTML.  Does anybody know if this can be done and if so how?

I have looked in SE61 and the text appears to be plain text however when email is sent it is sent with HTML tags.  Document GRAC_CUP_PSS_NOTIFY

We are using AC10.
