20 An e-mail gateway for Roundup.
22 Incoming messages are examined for multiple parts:
23 . In a multipart/mixed message or part, each subpart is extracted and
24 examined. The text/plain subparts are assembled to form the textual
25 body of the message, to be stored in the file associated with a "msg"
26 class node. Any parts of other types are each stored in separate files
27 and given "file" class nodes that are linked to the "msg" node.
28 . In a multipart/alternative message or part, we look for a text/plain
29 subpart and ignore the other parts.
31 Summary
32 -------
33 The "summary" property on message nodes is taken from the first non-quoting
34 section in the message body. The message body is divided into sections by
35 blank lines. Sections where the second and all subsequent lines begin with
36 a ">" or "|" character are considered "quoting sections". The first line of
37 the first non-quoting section becomes the summary of the message.
39 Addresses
40 ---------
41 All of the addresses in the To: and Cc: headers of the incoming message are
42 looked up among the user nodes, and the corresponding users are placed in
43 the "recipients" property on the new "msg" node. The address in the From:
44 header similarly determines the "author" property of the new "msg"
45 node. The default handling for addresses that don't have corresponding
46 users is to create new users with no passwords and a username equal to the
47 address. (The web interface does not permit logins for users with no
48 passwords.) If we prefer to reject mail from outside sources, we can simply
49 register an auditor on the "user" class that prevents the creation of user
50 nodes with no passwords.
52 Actions
53 -------
54 The subject line of the incoming message is examined to determine whether
55 the message is an attempt to create a new item or to discuss an existing
56 item. A designator enclosed in square brackets is sought as the first thing
57 on the subject line (after skipping any "Fwd:" or "Re:" prefixes).
59 If an item designator (class name and id number) is found there, the newly
60 created "msg" node is added to the "messages" property for that item, and
61 any new "file" nodes are added to the "files" property for the item.
63 If just an item class name is found there, we attempt to create a new item
64 of that class with its "messages" property initialized to contain the new
65 "msg" node and its "files" property initialized to contain any new "file"
66 nodes.
68 Triggers
69 --------
70 Both cases may trigger detectors (in the first case we are calling the
71 set() method to add the message to the item's spool; in the second case we
72 are calling the create() method to create a new node). If an auditor raises
73 an exception, the original message is bounced back to the sender with the
74 explanatory message given in the exception.

787 # Sorry for the huge checkin message - I was only intending to implement #496356

789 # . modified ROUNDUPDBSENDMAILDEBUG to be SENDMAILDEBUG and hold a filename
790 # for _all_ roundup-generated smtp messages to be sent to.
791 # . the transaction cache had broken the roundupdb.Class set() reactors
792 # . newly-created author users in the mailgw weren't being committed to the db

796 # . #496356 ] Use threading in messages

800 #
801 # Revision 1.45 2001/12/20 15:43:01 rochecompaan
802 # Features added:
803 # . Multilink properties are now displayed as comma separated values in
804 # a textbox
805 # . The add user link is now only visible to the admin user
806 # . Modified the mail gateway to reject submissions from unknown
807 # addresses if ANONYMOUS_ACCESS is denied
808 #
809 # Revision 1.44 2001/12/18 15:30:34 rochecompaan
810 # Fixed bugs:
811 # . Fixed file creation and retrieval in same transaction in anydbm
812 # backend
813 # . Cgi interface now renders new issue after issue creation
814 # . Could not set issue status to resolved through cgi interface
815 # . Mail gateway was changing status back to 'chatting' if status was
816 # omitted as an argument

821 # Revision 1.42 2001/12/15 19:24:39 rochecompaan
822 # . Modified cgi interface to change properties only once all changes are
823 # collected, files created and messages generated.
824 # . Moved generation of change note to nosyreactors.
825 # . We now check for changes to "assignedto" to ensure it's added to the

827 #
828 # Revision 1.41 2001/12/10 00:57:38 richard

831 # . #489760 ] [issue] only subject
832 # . fixed the doc/index.html to include the quoting in the mail alias.
833 #
834 # Also:
835 # . fixed roundup-admin so it works with transactions
836 # . disabled the back_anydbm module if anydbm tries to use dumbdbm
837 #
838 # Revision 1.40 2001/12/05 14:26:44 rochecompaan
839 # Removed generation of change note from "sendmessage" in roundupdb.py.

842 # Revision 1.39 2001/12/02 05:06:16 richard
843 # . We now use weakrefs in the Classes to keep the database reference, so

845 # I bumped the minimum python requirement up to 2.1 accordingly.

850 # There's now a clearly marked "TODO: append the change note" where I believe
851 # the change note should be added there. The "changes" list will obviously
852 # have to be modified to be a dict of the changes, or somesuch.

859 # backend is modified in this way - neither of the bsddb backends have been.
860 # The mail, admin and cgi interfaces all use commit (except the admin tool
861 # doesn't have a commit command, so interactive users can't commit...)
862 # . Fixed login/registration forwarding the user to the right page (or not,
863 # on a failure)
864 #
865 # Revision 1.37 2001/11/28 21:55:35 richard

958 # . hyperdb Class getprops() method may now return only the mutable
959 # properties.
960 # . Login now uses cookies, which makes it a whole lot more flexible. We can
961 # now support anonymous user access (read-only, unless there's an
962 # "anonymous" user, in which case write access is permitted). Login
963 # handling has been moved into cgi_client.Client.main()
964 # . The "extended" schema is now the default in roundup init.
965 # . The schemas have had their page headings modified to cope with the new
966 # login handling. Existing installations should copy the interfaces.py
967 # file from the roundup lib directory to their instance home.
968 # . Incorrectly had a Bizar Software copyright on the cgitb.py module from
