-
- There is an "MID" (Message IDentifier) associated with each message.
- If an MID is not given explicitly with the "Send" command, one is
- created automatically from the message number and callsign of the MailBox
- into which the message was initially entered. It has the form nnn_call.
-
-
- There are 3 types of messages:
-
-
- 1) Personal. If sent with SP, or with S and to a callsign.
-
- 2) NTS traffic. If sent with ST.
-
- 3) Bulletins. If sent with SB, or with S and NOT to a callsign.
-
-
- For backward compatibility, any message sent with Sx, where x is NOT
- B, P, or T is also considered a bulletin. These types have been
- used in the past for bulletin type sorting.
-
- Each type of message gets somewhat different handling:
-
- For NTS traffic, the LT, KT, and ET commands are active.
- For Bulletins, a BID (the MID) is sent when forwarding to MBL systems.
- For Personal, the message can only be rad by the sender, addressee, and sysop.
-
-
- There are several "flags" associated with each message. These are shown in
- the "message status" position in the "list message" display. Note that each
- flag has an associated "L" command, and some have associated "K" commands.
-
-
- F - The "Forwarded" flag:
-
- This indicates the message has been forwarded to all
- its destinations, but has not yet been killed.
-
- H - The "Hold" flag:
-
- This indicates the message is held.
- It will not forward, and can only be seen by the sysop.
-
- I - The "In process" flag:
-
- This indicates the message is in the process of being forwarded.
-
- K - The "Killed" flag:
-
- This indicates the message is killed, but has not yet been purged
- from the system. Killed messages are purged with the GM command.
-
- O - The "Old" flag:
-
- This indicates the message has been hanging around
- un-forwarded and un-read for too long.
-
- Y - The "Read" flag:
-
- This indicates the message has been read by its addressee,
- but has not yet been killed.
