Hi,
Please try mailing the editor from a University account. At times, the gmail/yahoo/hotmail type accounts get marked as spam. Please email the handling editor via email and perhaps again by means of using the online system. It is quite reasonable to inquire about the paper. Secondly, from minor revisions, I don't recall ever seeing papers going to major. At times, for minor, the Editors even simply check the revisions themselves.
Hope this helps,
Cheers
