[Mimedefang] Mimedefang + outlook express

[Berger Law]

Hi all,

I am using outlook express with mimedefang. Whenever i forward the email as
attachment, the following log came out.

Oct  4 16:34:38 xxxx sendmail[31463]: g948YUuL031463: Milter change: header
Content-Type: from
multipart/mixed;\n\tboundary="----=_NextPart_000_0829_01C26BC3.E7A1CA90" to
multipart/mixed; boundary="----=_NextPart_000_0829_01C26BC3.E7A1CA90"

X-Scanned-By: MIMEDefang 2.21 (www . roaringpenguin . com / mimedefang)

The consequence is that the recipient couldn't receive email with
attachment, but rather an email with plain text!!!
Anyone faces similar problem and how to solve it?

Thanks.
