When applying Rules to RecievedMail the Rule does not operate correctly and the Mail is not moved to the specified Folder. Please see the attached animated gif. Please note: the gif runs forever however eClient doesn’t.
The Spam filter Rule looks for messages marked as spam by your server. Typically that would not be Sent messages, only those in your Inbox. If the messages have not been marked as spam, then the Rule will not move them.
If this is for your custom Rule, can you give a screenshot of the Rule.
