On this tab, you can configure to which websites the server should be assigned. Two different options may be selected:
•The SMTP server is available for all websites - if chosen, the server will be designated as a global server. This means that it will accept e‑mails from all sites in the system and also handle mails that are not related to any specific website.
•The SMTP server is only available for the following websites - this option allows you to dedicate the server to specific websites. Sites may be assigned to the server by clicking the Add sites button and choosing from the list in the displayed dialog. The server will only process e‑mails that originate from the specified site(s).
More information about SMTP servers and e‑mail processing can be found in Developer's Guide -> Installation and deployment -> Additional configuration tasks -> SMTP server configuration.
