Well they are definitely leaving your PC, otherwise they would remain in your 'outbox' and not have copies in the 'sent' folder. The problem seems to be with your email provider's mail servers. You should contact them as I don't think it's a problem with your email client or your PC.

The problem revolves around the new(ish) system that Microsoft have brought in called TNEF, which effectively wraps up all attachments in a protective cover called winmail.dat. Microsoft's newer program can deal with this but older programs cannot. If you are running Windows XP with SP2 it seems that you are vulnerable. This is the problem which I am currently struggling with as the sender of e-mails using Outlook 2007 and although I cannot be sure that I have the answer, it seems that the receiver installing Windows XP SP3 may do the trick. There are apparently some conversion programs available from Microsoft which will solve the problem.
Sorry not to have the clear-cut definitive answer as yet but I thought you might appreciate my experience so far.
