Bug Description

The following messages detects the address in the body as permanent failure:

To: <email address hidden>
Subject: Not a bounce
From: "Manuel Vázquez Acosta" <email address hidden>
Content-Type: multipart/mixed;
 boundary="----=_NextPart_000_019D_01D16E41.7138C310"
X-Mailer: Anything will do to trigger the bug
--text follows this line--

This is a multi-part message in MIME format.

Content-Type: text/plain

De: <email address hidden>

Note: Some recent Microsoft Office Outlook versions are including the X-Mailer header and also use the Content-Type multipart/mixed.

But groupwise.py only ask for:

        if msg.get_content_type() != 'multipart/mixed' or not msg['x-mailer']:
            return NoFailures

Any X-Mailer will do confuse it.

summary: - groupwise detector has wide false positives
+ groupwise detector has false positives
