-Description of the custom MIME type "application/x-citadel-delivery-list"
-
- This MIME type may be found in the outbound queue room on Citadel systems,
-which is typically called "__CitadelSMTPspoolout__". The room is flagged as
-a "system" room, which means that it's completely hidden to everyone, although
-an Admin can get to it if the full name is specified (but unlike a normal
-hidden room, it does not appear in the known rooms list on subsequent visits).
-
- Messages in this format contain delivery instructions. Therefore, for each
-message in the queue to be delivered to one or more recipients, there will be
-*two* messages in the room: one containing the actual message, and the other
-containing delivery instructions. It is expected that the instructions
-message may be replaced at any time (using an Exclusive ID field) if delivery
-to only some of the recipients has been accomplished.
-
- Citadel keeps reference counts of each message on disk. Therefore if a
-message contains a mixture of local and remote recipients, there may be two
-or more references to the message itself, one of them being the one in the
-queue.
-
- A delivery list contains one or more lines of text, each line containing
-a single instruction (usually a recipient). Fields are separated by the
-vertical bar character ("|") and there will always be at least one field on
-each line.

-
- INSTRUCTION: msgid
- SYNTAX: msgid|0000000
- DESCRIPTION:
- Defines the actual message for which we are providing delivery
- instructions. This instruction must precede all the others. When
- all deliveries have either succeeded or failed, both the instructions and
- the copy of the message itself in the queue room should be deleted. The
- second parameter specifies the message ID in the local database.
-
-
- INSTRUCTION: submitted
- SYNTAX: submitted|999999999
- DESCRIPTION:
- Contains a timestamp designating when this message was first entered into
- the system.
-
-
- INSTRUCTION: attempted
- SYNTAX: attempted|999999999
- DESCRIPTION:
- Contains a timestamp designating the date/time of the last delivery
- attempt.
-
-
- INSTRUCTION: retry
- SYNTAX: retry|9999999
- DESCRIPTION:
- Citadel does not retry SMTP delivery at a fixed interval. Instead, it
-starts at a nominal interval (15 minutes by default) and then doubles the
-interval after each failed attempt. This instruction contains the interval
-which should currently be followed (and doubled again, if the next delivery
-fails).
-
-
- INSTRUCTION: bounceto
- SYNTAX: bounceto|Big Bad Sender[@host]
- DESCRIPTION:
- Where to send "bounce" messages (delivery status notifications). The
- contents of the second field are supplied as the "recipient" field to
- CtdlSaveMsg(), and therefore may be a local username, a user on another
- Citadel, or an Internet e-mail address.
-
-
- INSTRUCTION: envelope_from
- SYNTAX: envelope_from|blurdybloop@example.com
- DESCRIPTION:
- Sets a value to be used as the envelope sender during the 'MAIL FROM:'
- phase of the SMTP transaction. If an envelope sender is not supplied,
- one is extracted from the message body.
-
- INSTRUCTION: source_room
- SYNTAX: source_room|Citadel Support
- DESCRIPTION:
- when sending mailinglist rooms this contains the source room for displaying
- and messaging purposes.

--- Once per Remote-part per Queue-Item --
-
- INSTRUCTION: remote
- SYNTAX: remote|friko@mumjiboolean.com|0|delivery status message
- DESCRIPTION:
- Names a recipient on a remote system to which the message should be
- delivered. The third parameter may contain any of the following values:
- 0 = No delivery has yet been attempted
- 2 = Delivery was successful
- 3 = transient error state; like connection failure or DNS lookup failure
- 4 = A transient error was experienced ... try again later
- 5 = Delivery to this address failed permanently. The error message
- should be placed in the fourth field so that a bounce message may
- be generated.
