A friend of mine is having problems with large numbers of "Your EMail was Undeliverable" type messages coming into his inbox.
The original messages contain a 'Please Send Money' scam and were not sent from my friends account, someone is just spoofing the 'From' address.
The problem is that the SPAM-bot is sending out a massive numebr of emails but many are to accounts that so not exist - hence the undeliverable errors. He is using Outlook Web Access (provided by his ISP) and does not have the ability to mark messages are Junk or to create a Rule that will scan the body of the email (only the subject and sender). I have been able to create some basic rules to move many of the messages to the Deleted Items folder (based on a common subject) but I'm worried about being too generic in case I end up deleting genuine messages.
How can I stop these messages from filling up his Inbox/Deleted Items..?
Thanks in Advance
