We've been using Roundcube to get email from web for a few years. We taught spam by moving the email to "Learn Spam" or "Learn Ham". So over time the program automatically put re-occuring emails that had been identified as "Spam" into a Junk folder. There are times every month that the filter makes a mistake throwing a client email into junk because of a word in the subject line or other reason I can't identify. So I have been checking them weekly then trashing. All of a sudden, as of Nov 1, nothing is being put in the Junk folder. Everyday I am moving spam emails into "Learn Spam" yet the next day the Junk email is empty. I used to have 6 to 25 emails daily in the Junk folder to check. Monthly I would find 1 email that shouldn't be in there.
Is the system automatically deleting what it has learned or thinks is spam? Is there a setting that can be changed so that the junk is put in junk based on setting and what has been trained?
I need help because this affects 6 of my employees emails. Clients expect teh emails have been delivered yet I cannot be sure that they all will be.
