At the moment, given a users' ability to block Senders with one-click (and soon - to proactively block entire domains!), lockrMail does not have a spam filter enabled for the emails processed through its servers. This feature, if built, would scan incoming emails across all accounts for emails that look like spam and would block those emails from being delivered through to Destination email addresses. Similar to existing email solutions, lockrMail would build a spam folder in the dashboard, allowing users to view (and deliver) emails marked as spam in case of any error. Users would also have the ability to flag Senders in their dashboard as spam if they are coming from unapproved accounts - that way future communications from that Sender would come through the Spam folder rather than showing in the main dashboard.
