Hidden lines in the message body

[Rodolfo Medina]

Hi to all Gnus users.

I' attaching a text file containing eight lines.  If I insert it in a message
(e.g. with `C-x i') and then send the message, in the message body only the
first and the fifth will be visible, the others won't.

Can anybody explain why this happens and how to avoid it?

Thanks for any help,
Rodolfo
