vRealize Automation notification emails are sent using SMTP. These emails include notification of machine creation, expiration, and the notification of approvals received by users. vRealize Automation supports both anonymous connections to the SMTP server and connections using basic authentication. vRealize Automation also supports communication with or without SSL.
You create a global, inbound email server to handle inbound email notifications, such as approval responses. Only one, global inbound email server, which appears as the default for all tenants, is needed. The email server provides accounts that you can customize for each user, providing separate email accounts, usernames, and passwords. Each tenant can override these settings. If tenant administrators do not override these settings before enabling notifications, vRealize Automation uses the globally configured email server. The server supports both the POP and the IMAP protocol, with or without SSL certificates.
