Email server

The user interface for editing the mail server settings. Other than some general connection settings you can also change how supoprt request emails are sent.

When a global mail server was configured and a client did not specify their own mail server, the global mail server is used for that client. Otherwise, the mail server of the client is used. When no global mail server was configured, sending emails is disabled for the entire system.

Since version 7.3.0+  it is possible that the system administrator deactivates the usage of the system wide email server for a client and also the configurability of the client specific server (see here). If this is the case or, if applicable, no client-specific e-mail server is configured, corresponding functionalities with mail delivery are not available.

This menu lets you setup a global mail server. A mail server is required to sent emails. Sending emails may be necessary for certain functionality such as sending a user their login details. The mail server settings consists of three sections.
