What it is

Scrollout F1 is a free email gateway that adds anti-spam and anti-virus protection to existing mail servers. It lists Microsoft Exchange, Lotus Domino, Postfix, Exim and Qmail among compatible servers, and one installation can protect unlimited domain names and email servers. Mail controls include DKIM signing and verification, SPF verification with SRS for forwarding, DMARC support and recipient checks through Active Directory or LDAP. Filtering covers executable files, malicious content, scripts, forged domains and invalid or unknown hosts. Routing features include smarthost relaying, per-domain outbound IP pools, backup delivery and fallback to alternative servers. The gateway offers separate quarantines, per-domain spam scoring, TLS 1.2 and an option to require encrypted server connections. Deployment options include Hyper-V, VMware, VirtualBox, KVM, XEN and bare metal; OpenVZ is not supported. It is available as a 64-bit ISO or install-from-scratch option, both requiring internet access during installation.
