My organisation is using MDaemon Mail Server. Recently users including myself have been receiving blank emails. There is no address at all from the sender(FROM:), no address in the TO: field and no test in the SUBJECT: field. There is no text as well in the message body. Has anyone ever come across this problem? Or does anyone have any idea why this is happening? What can be done to stop this. Sometimes receipients of emails outsie my organisation tell us that they have been receiving blank emails from us too. Any ideas from anyone would be very much appreciated.
