The Bat mail client and Redirect option


New Email
I am using the Bat mail client and when I try to go to my sent folder and right click on an email which was send previously to resend it to another client, I use option : "Redirect Ctrl+E".

But the previous email comes an attachment : "message.html", what should I configure to prevent the previous email to come as attachment "message.html" ?

Right now what I am doing , I delete this attachment whenever I use "Redirect Ctrl +E"option and this is annoying.
