Mail queue is full

For some reason the mail queue gets filled with mail that I have no ability to easily view. I would love to see what they are and if it’s possible to have the mail settings setup (but where to??) in order to clear the mail queue. I’ve been manually clearing them by using: Postsuper -d ALL

I’ve looked under Admin --> System Admin --> EMail Setup. I get voicemail notifications without any issue but it’s these that I am confused.

Here’s a snippet from the logs:
