Hi All,

I'm receiving spam that does not meet RFC822 minimum requirements which means the sender is blank. Does anyone know a trick to block messages in outlook that do not meet the RFC822 minimum requirements? I played a little with rules but nothing jumped out. Please note in this scenario it is mail I am recieving from my ISP (personal e-mail account). From what I see in google a lot of people have experiance this but no one knows of a way to block it. I do forward as attachments all the messages to the missed-spam addresss and abuse address of my ISP. I have requested the ISP block mails that qualifiy but so far it is not working. The only spam I receive comes in this format and I would love to write a rule to block it. Posted in ms security since I would like to block it using outlook but it is a symthom of a much larger problem and people with other clients are experiancing the same issue.

Thanks,
-D
