Always add headers to mail checked by SpamFilter with Plesk installed on Windows OSes
For now SpamAssassin on Plesk for Windows does not add any headers to mail messages which were processed by it and not identified as spam. It would be good feature to add header showing that SpamAssassin actually processed this messages to all mail messages, even not spam one.
This could be helpful in order to monitor SpamAssassin functionality to understand if it works in general or not. Plus, some Spam checkers may show that mail inside mailbox were not checked at all, which is concerning.
Thank you for your input! We will consider this functionality in upcoming releases if it will be popular.
Everyone, please continue voting for this feature if you consider it important.
