Our verdict on Scrollout F1

Scrollout F1 is a free, self-hosted email security gateway for organizations that operate their own mail servers. It filters incoming and outgoing mail traffic with anti-spam and antivirus protection, per-domain quarantine, spam scoring, authentication checks, malicious-content controls, and routing features. Linux and Windows administrators can deploy it as a virtual or bare-metal gateway alongside Microsoft Exchange, Lotus Domino, Postfix, Exim, or Qmail.

Its security coverage is broad for a free gateway. DKIM verification and signing, SPF verification with SRS forwarding support, and DMARC policy support address key email-authentication workflows. Active Directory and LDAP recipient verification can help validate recipients, while controls for executable files, malicious content, and scripts add another filtering layer. Encrypted connections to mail servers, fallback delivery to alternative mail servers, and outbound IP pool assignment by sender domain extend the product beyond basic spam filtering. These features make it suitable for teams that want mail-flow controls in front of an existing server estate.

The main trade-off is its deployment focus. Scrollout F1 is designed as a gateway managed by administrators, so it fits organizations with existing mail infrastructure rather than teams seeking a hosted mailbox-security service. Its listed ecosystem centers on traditional mail platforms, and organizations built around Microsoft 365 or Google Workspace should choose a product with explicitly documented support for those environments. Teams comfortable operating a Linux or Windows gateway and needing free authentication, quarantine, filtering, and routing controls should consider Scrollout F1; teams wanting a managed cloud service or broader modern collaboration-platform coverage should look elsewhere.
