[imp] attachments not showed with IMP 5.0.18

Wed Feb 8 13:00:54 UTC 2012

Hello,

I am testing IMP 5.0.18 and when a mail is forwarded beetwen systems the attachments become unrecognizable. 

In this example the MIME part image/jpeg is showed as octect-stream by IMP and clicking over the attachment link the popup windowns said "Could not auto-determine data type". 

any idea about where the problem  can be?
