osTicket is the world’s most popular customer support software.

Admin Checklist

  • Do not remove the email address of osTicket Alerts under 'Email Addresses'. This mailbox is managed by Cloudron. The email address can be changed from Cloudron dashboard's Email section. To change other settings like the Email Name, the osTicket UI requires the SMTP password. You can get this by opening a Web Terminal and executing env | sed -n -e 's/CLOUDRON_MAIL_SMTP_PASSWORD=//p'.

  • Change the administrator email under Emails -> Email Settings and Options. If you miss this, osTicket will send alerts to this address and bounces get attached to tickets.

To workaround agents must be manually added into osTicket before they can login. When adding an agent, choose LDAP as the authentication backend.
