I’m trying to notify my hosted Mautic instance of bounces and complaints.  
  
  
  
I know for sparkpost the URL is [Myinstall]/mailer/sparpost/callback and for Mandrill is [Myinstall]/mailer/mandrill/callback  
  
  
  
What if i’m using other smtp server to send emails? What is the callback URL?
