Eudyptula Mail Format Issue

[me storage]

Hi All,

I has been participating in this challenge from 8 months. I submitted 5
tasks.
Today i submitted my task06 results third time , but intently it's giving
reply that "the format is *base64,* So please change and resend it again"

So can any please tell me what happened ? because i followed the same
approach as previous tasks.

Thanks.
