      Essentially the same as the SMTP but for the inbound message.

      When connecting to some email servers you might happen to get errors like the following with Courier (see MDL-53315)

      php admin/tool/task/cli/schedule_task.php  --execute='\tool_messageinbound\task\pickup_task'
      		 
      Execute scheduled task: Incoming email pickup (tool_messageinbound\task\pickup_task)
      		 
      Connecting to mail.catalyst.net.nz as moodle@moodle.catalyst-au.net...
      		 
      Connection established.
      		 
      Unable to find the 'tobeconfirmed' mailbox - creating it.
      		 
      Unable to connect to IMAP server. Failed with 'IMAP error reported by server.'
      		 
      ... used 6 dbqueries
      		 
      ... used 3.7367041110992 seconds
      		 
      Scheduled task complete: Incoming email pickup (tool_messageinbound\task\pickup_task)

      There is no easy way to debug this
