NM> After I updated my Pine speed tips to include the tip about rules and
NM> "recent" messages, I started thinking about "recent" messages and have
NM> some a terminology question. Here's how I think this works: The
NM> messages in a mailbox are partitioned like this:
NM> [...]
NM> * Every message is either Seen or Unseen where "Seen" means that the
NM>   message has been opened and viewed.
NM>
NM> * Every message is either Recent or Not Recent where "Recent" means
NM>   that the message was added to the mailbox since the last time you
NM>   opened the mailbox.
NM>
NM> * Every message is in one of the following 4 categories
NM>    (A) Seen and Not Recent
NM>    (B) Seen and Recent
NM>    (C) Unseen and Recent
NM>    (D) Unseen and Not Recent
NM>
NM>   The interesting category is (B) Seen and Recent. If a mailbox is
NM>   closed, then these are messages that were viewed in another box and
NM>   then moved to this box. If a mailbox is open, this type of message
NM>   is Recent and EITHER was opened in & moved from another box, OR the
NM>   message was viewed during this mailbox session.
NM>

NM> My Question: Am I correct that this is the way that messages in a
NM> mailbox are partitioned?
