That will depend on the retraining process complexity as well as the size of 
the messages. 
My guess is that without some real world testing it will be difficult to have a 
definitive answer.

Yes, I thought about those two options (well, only the first one 
actually, since notifyd can only spawn an external program) and I asked 
about it in my original message.
The question is, is it really necessary (with ~100 sessions and not 
everybody constantly moving messages in/out of the spam folder)?

Ah… we use different meaning for the “SPAM” folder! For me it’s where I place 
mail that was wrongly classified as HAM. Mail classified as SPAM go to the 
“quarantine” folder (that get’s purged by Cyrus after X days).

You are talking about moving files out of “quarantine” and using a notification 
to trigger the retraining. That’s indeed a nice idea! 

I see a 2 ways to handle it:

- Enqueue for later processing
- Make notifyd pass the job to another process (like a daemon)

The problem with any of this methods (really with any solution based on 
notifications that is not completely handled in the notification processing) is 
that the use may further move the message.

One option is to make a copy of the message to another (reserved) folder. I may 
be wrong, but my guess is that Cyrus will just link the messages, so it can be 
quick. If not I guess it can be linked during the notification processing. Need 
to check.

Arnaldo.

That's what I've been doing for many years (using a couple of shared 
folder where users have to move messages that have been wrongly 
classified)  but I wanted to make it simpler, like the dovecot antispam 
plugin, where it is enough to move a message in/out of the personal spam 
folder to trigger a retrain.

I run a separate daemon that periodically checks the spam folder, perform the 
necessary “training” actions and then remove the message.

sa-learn using event notifications

[Luca Olivetti]

I wrote a simple program that manages the vnd.cmu.MessageMove event to 
run sa-learn when a message is moved into or out of the spam folder.
I'm processing it synchronously (i.e., the program starts spawned by 
notifyd and doesn't terminate until sa-learn exits).
Given that sa-learn takes a few seconds to run, could it lead to 
problems? Should I devise a different strategy (i.e. queue sa-learn to 
run later/asynchronously)?

I don't have many users (around 100 active sessions).
