SpamAssassin Rule: FORGED_MUA_OUTLOOK

Standard description: Forged mail pretending to be from MS Outlook

Explanation

The message headers include those generated by Microsoft Outlook, such as X-Mailer, but the syntax is not the same as created by genuine Microsoft software.

This suggests that the message was created by a mailout program rather than a user with a Microsoft email client.
