MailScanner header tags added to message body

[pippo at olidata.eu]

Hi,
 
I'm working on this since some days and can't figure out how to solve.
I installed MailScanner few days ago on a Ubuntu Server 8.04 LTS +
Postfix. The server acts as a gateway and sends scanned mails to an
Exchange 2003 Server.
Mail flow is correct and MailScanner seems to work (at least it adds the
banner). The problem is that the various changes to message headers, are
not made to message headers, but:
- are not made at all if message is in HTML format
- are added on top of message body if message is in text format.
I could't find anything about this issue in documentation, nor in
Google.

Where am I wrong ?

Thanks.

Massimo.
