SpamFilter spools emails to be quarantined in the \SpamFilter\quarantine folder. These files will be named something like Qrtn_SomeGUI_.tmp while they are being added to the database. If the database operation fails for some reason, SpamFilter will append the extension ".queued" to the filename, and will create another file with the same name but extension ".info" which will contain the header (to/from/subject/date etc) information for the email. From then on, SpamFilter will retry automatically to resend the emails to the quarantine when the database comes back online. Sometimes SpamFilter is unable to communicate with the database until SpamFilter is restarted. In this case, it will again retry populating the database with the queued emails shortly after being restarted.
It's possible that there are .tmp files left over due to other issues that may occur during these failed attempts. Unfortunately it's impossible to tell if the emails contained in those files were actually quarantined or not without looking for them in the database. These leftover .tmp files can be removed manually at any time. We opt to leave them on disk as, since unrecoverable errors caused them to be left there orphaned, admins may look thru them in case they lost critical emails that cannot be located elsewhere.
