[imp] Imp attachment issue

[Nicola Murino]

Hi list,

I'm running the last stable horde (3.1.2) and imp (4.1.2) releases, I
have a little issue:

if i receive a mail with an attachment I see the link to download the
attach and a link "unmamed [text/plain]" that allow to download the
message body, 

which option in which imp config file have I to modify to hide "unmamed
[text/plain]" download link?

thanks
Nicola
