I use Outlook 10 with Microsoft exchange. I have one of my email accounts that looks like it is is being phished with emails from the this address 'Postmaster@msg.strl.va.charter.net' indicating I have emails that are undelieverable because other server is not reachable. I have blocked this sender but it is still coming through. Makes me think the pst file may be corrupted and is the source - not external. Anyone had this problem or do you know how to fix it?
