A mailbox configuration in a RAS Farm is used to send invitation emails to users to join a Parallels RAS Farm and to send event notifications to other email addresses. A Farm can have just one mailbox configured.
To configure a mailbox:
Navigate to Farm Settings > Mailbox.
Click Edit and specify the following:
Mail server: Enter the mailbox server name. For example, mail.company.com:500
TLS / SSL: Choose whether to use the TLS/SSL protocol.
SMTP server requires authentication: Select this option if your SMTP server requires authentication. If it does, also type the username and password in the fields provided.
Sender information: Enter the email address.
Click Save.
