I installed this plugin and added the correct configuration settings for my email host server and port number. This should have worked, however when I tested out the contact page, I was not receiving any messages. I also assed a DKIM TXT record to my DNS as a stronger verification. As a former specialist with a hosting company, and working with o365 mail, I have been through this process to understand that their is no reason why I should not be receiving these emails. I used the same settings for my inboxes to add to Gmail, which it worked just fine. So I am confused on how a process I know should work is not working. I do not want to upgrade if this is an internal error, unrelated to the developer side.
