Submit false positive emails directly from the quarantine server
An option in the quarantine server to release to end user AND submit to the notspam-feedback email address. Or maybe if the quarantine server could actually get a EML or MSG version of the email
Recently ran into an issue where a bunch of legitimate emails got sent to the quarantine server. After opening a support ticket to see if there was an easy way to submit them to the notspam-feedback email address, there didn't seem to be any "easy" way to do it.
Unfortunately the only way to do it seems to be to get all the users that have false positive emails that was released from the quarantine sever to send each email to me as an attachment and then for me to forward to the notspam-feedback email address.
