-Incoming messages are examined for multiple parts. In a multipart/mixed
-message or part, each subpart is extracted and examined. In a
-multipart/alternative message or part, we look for a text/plain subpart and
-ignore the other parts. The text/plain subparts are assembled to form the
-textual body of the message, to be stored in the file associated with a
-"msg" class node. Any parts of other types are each stored in separate
-files and given "file" class nodes that are linked to the "msg" node.
+An e-mail gateway for Roundup.
+
+Incoming messages are examined for multiple parts:
+ . In a multipart/mixed message or part, each subpart is extracted and
+ examined. The text/plain subparts are assembled to form the textual
+ body of the message, to be stored in the file associated with a "msg"
+ class node. Any parts of other types are each stored in separate files
+ and given "file" class nodes that are linked to the "msg" node.
+ . In a multipart/alternative message or part, we look for a text/plain
+ subpart and ignore the other parts.
+Summary
+-------
The "summary" property on message nodes is taken from the first non-quoting
section in the message body. The message body is divided into sections by
blank lines. Sections where the second and all subsequent lines begin with
a ">" or "|" character are considered "quoting sections". The first line of
the first non-quoting section becomes the summary of the message.
+Addresses
+---------
All of the addresses in the To: and Cc: headers of the incoming message are
looked up among the user nodes, and the corresponding users are placed in
the "recipients" property on the new "msg" node. The address in the From:
register an auditor on the "user" class that prevents the creation of user
nodes with no passwords.
+Actions
+-------
The subject line of the incoming message is examined to determine whether
the message is an attempt to create a new item or to discuss an existing
item. A designator enclosed in square brackets is sought as the first thing
"msg" node and its "files" property initialized to contain any new "file"
nodes.
+Triggers
+--------
Both cases may trigger detectors (in the first case we are calling the
set() method to add the message to the item's spool; in the second case we
are calling the create() method to create a new node). If an auditor raises
an exception, the original message is bounced back to the sender with the
explanatory message given in the exception.
