[horde] Not sure if this is an IMP or horde error, (Attachments)

[Jeffrey Steinbrecher]

Hi, i'm running Horde and IMP (latest stable versions) using IMAP 
authentication from an exchange (5.0 i believe) server. When an 
attachment is sent from an outside e-mail address it shows up fine. When 
an attachment is sent using IMP, its also fine.

but when someone within the office network uses outlook express to send 
an attachment, it doesn't show up in IMP. IMP tags the message with an 
attachment icon, and the size of the message reflects the size of the 
attachment, but when you open the message to view it - there is no 
mention of the attachment or any option to download it.

thanks guys
