I have a friend who use bigpond as their ISP (Aust). They have a vista system & use windows mail as her local mail client.
When emails arrive some are arriving with no attachments, while others turn up with attachments as expected. There doesn't seem to be any consistency as to why to help troubleshoot. I can logon to their webmail account & see the email with the attachment, yet when i open the mail client & pull it down from the server, the email arrives with no attachment.
There have been some attachements that are showing as 'winmail.dat' on the mail server, which i pinpointed to Outlook 2010 mail format & I've asked them to ensure the senders are sending the emails in HTML or Plain text, doesn't seem to make any difference.
They run Norton Int Security locally.
I'm kinda running out of options to troubleshoot this & was wondering if anyone has seen this or solved a similar problem before?
