[Mimedefang] Altering mail attachment using Mime defang

[vinita batra]

Hi,
I am using the sendmail server.

 Suppose  some userA sends the mail to  userB which contains some
 attachment.

 I want to download this attachment and then want to send it to Windows
 Webserver for some modifications.

 After doing the modification I want to send the modified attachment to
 Sendmail server so that the modified attachment is received to mail
 recipient.

 Please tell me how to download the attchement at sendmail and how to
 send it to windows webserver.



 Thanks and Best Regards,
 Vinita Batra.
