I just received error notification from MailScanner.


Other Bad Content Detected –

Report: MailScanner: Message attempted to kill MailScanner



Then I try to review the mail from archive. Temporary bypass scanning and deliver to my box. The mail contain another attached email which contain attached email too which  finally contain JPG image.

I try to forward to myself this time I get: 

The following e-mails were found to have: Other Bad Content Detected - 


The question is how I can debug those email and to find what exactly cause the issue.

Possible reasons for me are: 

-       Bad character in the subject  because the Subject is 

“Subject: =?UTF-8?Q?Fw:_Fwd:_Re:_?=




-       TNEF just cannot process attached email. From this perspective how I can extract winmail.dat from the message and to process it manually with TNEF.
