5	Probe submission	An X.400 probe was submitted by a local email client (usually through the Store).
6	Probe transfer out	The MTA completed transfer of responsibility for a probe from the local MTA to a gateway, X.400 link, or another MTA.
7	Message transfer out	The MTA completed transfer of responsibility for a message from the local MTA to a gateway, X.400 link, or another MTA.
