The ejtermsetup.exe application would have asked you if you wanted to start the ejScheduler service that is responsible for periodically running the console applications ejournalcron.exe and importmail.exe.
These applications in turn will perform tasks like importing email, sending email, activating postponed tickets, and other tasks. If you did not let the ejtermsetup.exe start the scheduler for you, you should do it manually when you are ready:
Open the Control panel
Choose Administrative tools
Click the appropriate eJournal Scheduler <sitename> for your site.
Select Start Service
To start the service at boot, right click eJournal Scheduler, select Properties and make sure Startup type is set to Automatic.
Click Start to start the service.
