A survey of Spam-related keyword usage by IMAP clients.

[Lyndon Nerenberg]

[ Note: this message was originally sent to the IMAP Protocol and
IETF IMAP Extensions WG mailing lists. It was motivated by recent
discussions towards resolving the currently inconsistent keyword
usage by IMAP clients when flagging the "spam status" of messages. ]

It's time to get a current view of how IMAP clients are using keywords
to manage spam. If you are a client author I would appreciate it if you
could take a moment to send me a note describing which keywords your
client uses for spam-related processing, and what each of the keywords
signifies. If your client does not use keywords for this purpose, that's
valuable information, too, as is a breakdown of functionality by
software version number if there are significant differences. (If you
use non-keyword facilities to manage spam feel free to include a short
description of your methods if you think the info might be relevant.)

I'm primarily interested in getting authoritative data from the client
authors, but others should feel free to chime in with deployment-based
experience of related keyword usage, but please indicate the source of
your comments (e.g. deployment experience, source code examination).

I will summarize the responses to the imap-ext list in a couple of weeks
(or sooner if the response rate dictates.)
