Preventing repeated Router, SMTP and IMAP crashes caused by problem messages
Processing a problem message repeatedly can cause a server crash. If a message being processed at the time of a Router, SMTP, or IMAP crash remains in the mail.box database or mail file, processing the message again when the server is restarted can cause another server crash.
In IBM® Domino® 9.0.1 Social Edition 9.0.1, at the time of the crash, Domino now uses an exception handler to save the information identifying the message that caused the crash to the file system. Upon server restart, Domino uses the information to find the message and quarantine it.
