Hi Gabriele! Just chiming in with the information I have:
To what providers? <-- RSpamD currently is the only one I'm aware of, but its possible its passed to others. Might need to check with development on this to confirm.
How does it works? <-- Development would need to chime in on any technicals, but essentially the EML is submitted to HAM/SPAM interfaces for learning. How and what criteria is applied though is specific to the engine being used. I do know that we don't submit right away, there is a delay to prevent accidental clicks from being submitted immediately.
Wher is the training folder(s)? <-- C:\SmarterMail\Spool\Training
are there are separate SPAM and HAM folders? <-- There will be two folders contained in the directory, one for spam and one for ham. Both will contain EMLs submitted to junk or moved to the inbox.
Ho can we use that (I'm imagining a scheduled script that collects HAM mails and SPAM mails and sends them to a third-party antispam system, for example in my case Fortimail...)? <-- I'm not sure how Fortimail would interface with this, but you could certainly set that up on their end to take advantage of the data in these folders.
