Scrollout F1 is a free email gateway and antispam solution designed to protect existing email servers without requiring migration or costly implementation and maintenance. Built for Linux and Windows administrators, it aims to make email security straightforward, with a basic deployment designed to be ready in around 30 minutes. The gateway combines open-source security tools with additional rules and filters to provide multilayer spam and antivirus protection for unlimited domains and email servers.

Features include TLS encryption, spam tagging and blocking, separate quarantines and filtering scores by domain, DKIM and SPF verification, DMARC support, and recipient checks through Active Directory or LDAP. It also helps defend against malicious attachments, forged sender domains, and suspicious hosts. Administrators can configure message backups, fallback delivery, outbound mail routing, IP pools, and domain-specific policies through a secure panel. Scrollout F1 is available as a 64-bit ISO image or for installation from scratch, and can run on supported virtual platforms or bare-metal hardware. The project invites users to contribute donations and share reviews.
