Pada tugas 7 ini penulis mencoba menunjukan bagaimana attachment yang berbentuk image file di encoding oleh MTA untuk dikirim ke alamat tujuan.Pada tugas ini penulis memanfaatkan layanan Yahoo mail yaitu sebuah layanan free mail dengan web based application. ketika kita mengirimkan sebuah email dengan attachment file image maka ketika MTA Yahoo Mail gagal menemukan alamat yang dituju maka email yang kita kirimkan berikut attacmentnya akan dikembalikan ke mail box kita, tanpa berusaha mengembalikan ke bentuk file awal.
Berikut bentuk mail dan berita pengembaliannya dan encoding dan type dari attachment yang dikirim :

I’m afraid I wasn’t able to deliver your message to the following addresses.
This is a permanent error; I’ve given up. Sorry it didn’t work out.
:
Sorry, I couldn’t find a mail exchanger or IP address. (#5.4.4)
