[Mimedefang] replacing the attachment in MIMEDefang

[raan]

Hi All,

I am newbie to MIMDefang. I want to change my attachment say abc.doc to
encrypted abc.doc.

I was searching for various methods available but I could only find the
method for changing the attachment with URL. I could not find any method
that could replace my attachment .

Can you tell me how can I only replace the attachment of the mail with
another document.

Rgds,
Raan
