Email Multipart/alternative attachment?

[stuffradio]

I have a script here that downloads attachments. When it's sent via email from a mobile it doesn't work... but on a normal email it does work. When I run the script from a mobile email it downloads the file as '.alternative'.

 

I hope someone can help me
