[Dovecot] mail messages moving between mailfolders

[taras at elantech.ru]

Hello to all!

I'm using IMAP-based antispam self-learning. I have a folder "spam" in 
each Maildir in which I place spam-tagged messages during delivery. If 
antispam filter makes mistake, user can drag'n'drop message to/from 
"spam" folder. I running perl-script periodicaly and retrain spam-filter 
(dSpam). Now I must scan all messages, but it's not a good practice 
(server load depends from mail volume, not user activity) so I want add 
a "hook" to IMAP-server,  i.e. I  want server to report me something 
like "date: file1 -> file2" via any IPC (socket?) or log file while user 
moves messages across different mail folders. Overload from antispam 
retraining will be function from user activity with such feature added.

P.S.: Now I'm using courier, but want to try dovecot.

Sorry for bad English.
With respect, Taras.
