The score is added to the email header and the recipient can then filter based on this. We also scan all messages for viruses. If a virus is detected, the message is cleaned and a warning is attached that some message content has been removed along with additional details about the specific virus. We try to never “silently” bounce any email. Either the sender or the receiver should be notified if a message hasn’t been delivered along with an explanation.
