I use Outlook Express under Win 98. After several years of trouble-free operation (apart from people sending me viruses and spam, which I can cope with), in the last few days, all my emails have started coming in with incorrect dates on them. Messages are currently dated to a specific day (I have seen 8th, 9th and 10th) of May 2004. This means they get sorted to the bottom of the inbox which is inconvenient, takes a lot of work finding and meant that until I figured out what was happening, that I missed one or two important ones.

I have looked at the message headers and it could be that the problem lies with my ISP, as the incorrect dates are usually displayed in the message codes.

I have checked and re-set the time/date on my computer and have cleared the inbox out completely, without apparently solving things.
I can't find any reference in the Help areas of the programme, nor did a Google turn up any immediate suggestions. So I thought I'd let the Mudcat brains have a go. Has anyone else had this problem, or have an idea what is causing it?
