I recently submitted a self-authored article with no affiliation to a peer reviewed journal, which then got desk rejected. The email however wasn't a generic one; the editor made a comment about its content that clearly indicates he read the whole thing, but he didn't correct me or say anything that indicates that the paper was of low value. He then said that the paper was out of the journal scope and then suggested some other journals to transfer my paper to. Does this mean he thinks my paper is publishable? Or is this just routine?
