Spam training

My email host doesn't have a spam filter, can you integrate with something like SpamSieve?

Spam filtering and training are currently handled by your email provider, Gmail, Outlook, or your IMAP service, because they have the strongest signals and controls for managing spam. If a legitimate message is marked as spam, the best way to retrain the filter is to move it out of the Spam folder using your provider’s “Not spam” action. We don’t currently offer a separate spam-training control in Newton. We’re also working on a Block Contact feature, which will let you explicitly block a sender and automatically delete future emails from them.
