[otrs] Not receiving all notifications

Hey all, I am not getting all of my notifications. If I click "follow up" while viewing the ticket and send an email, it is never delivered to the user or agent. I also do not get a notification if I create a ticket via email. The ticket is created, but no notification. If I create an email ticket from within OTRS, then a notification is sent. I can reply to that ticket created email and then the agent receives a follow up notification. What is going on? I am sure it is something easy, but I am just not seeing it or thinking of it. Thank you all for the help! Wes Sothard
