Mailbox Posting Issue

I'm trying to setup EasyBlog Mailbox Posting, but am having some issues.

In the settings, I have everything setup, and running a test works fine. However, when I attempt to run via cron I've receiving the following in the CRON report:

HTTP request sent, awaiting response... 301 Moved Permanently
Location: https://domain/index.php?option=com_easyblog&task=cron

And when running the URL from the browser I receive the following:

{"emails":{"status":200,"type":"info","message":"There are no pending emails that needs to be dispatched currently."},"email_import":{"status":200,"type":"info","message":"No emails found in mailbox. Skipping this."},"twitter_import":{"status":200,"type":"info","message":"No Twitter accounts associated on the site. Skipping this"},"scheduler_publish":{"status":200,"type":"info","message":"No scheduled posts to process currently."},"scheduler_unpublish":{"status":200,"type":"success","message":"Executed query to process posts to be unpublished."},"scheduler_remove_tmp_files":{"status":"","type":"","message":""},"scheduler_remove_blank_posts":{"status":200,"type":"info","message":"Blank posts removed"}}

It's telling me that there are no emails found in the mailbox, but there are 2 test emails that were sent, and they are still sitting there in the mailbox.

Any thoughts?
