Overview

When attempting to use the Request File or Send File feature in Serv-U, the system prevents the action from completing and displays an error indicating that outbound email to recipients has been disabled by the administrator. This behavior is controlled by specific email-related policies within the Serv-U configuration.

Product section

Serv-U Managed File Transfer & Serv-U FTP Server

Cause

This error occurs when the Serv-U domain or server-level setting “Send the guest access link to the recipients” is set to Never. When this option is set to Never, Serv-U blocks File Share actions because these features rely on sending email notifications to external recipients.

Resolution

Open the Serv-U Management Console.
Navigate to either:
Domain > Domain Limits & Settings > File Sharing, or
Global> Server Limits & Settings > File Sharing, depending on where the restriction is applied.
Ensure that “Send the guest access link to the recipients” is set to Optional (Default) or Always.
Retry the Request/Send File Share operation.
