I haven't yet fully read this draft, but this is definitely useful
functionality to have. For Dovecot, solutions that monitor the spam
folder have been used for years now. This automatically triggers spam
learning activities when a mail is either moved into or moved out of the
spam folder. Historically, this was performed by an external plugin, but
more recently this is done using IMAPSieve. Additionally, using a sieve
language extension, MARF reports (RFC 5965) can be sent:
https://raw.githubusercontent.com/dovecot/pigeonhole/master/doc/rfc/spec-bosch-sieve-report.txt


The Ordogh draft adds a new command instead. I am not sure what I prefer
more. Adding a new command is problematic in that it requires client
support, which some clients will never attain. The problem with the
implicit reports based on folder events is that you're never quite a
100% sure it is what the user intended, and moving lots of messages can
produce problems.
