The first number is the time() the message was received; the second number
if non-zero is the explicit time() when the message should expire.

the last field can consist of space-seperated path names for the article,
it can be blank, it can be the string "cancelled", or it can be a set
of message-IDs. I don't remember the use of that last case except that
it's only used when the article has not yet been received but has been
spotted in References: lines.
