Unix mail files.

[Paul Griffiths]

Hi,
   Is there anyone out there who can tell me how individual messages
in a mailbox (ie /usr/spool/mail/$USER) are seperated from each other.

   The only distinguishable feature I can see is that each message begins
with a line specifying who the message came from, ie

	From Info-unix-requests at uk.ac.nsfnet-relay

   Note that the "From" has NO `:' following it. Am I on the right track ???

   Any help much appreciated.
