In their own words
Hermes Secure Email Gateway
Hermes Secure Email Gateway is a self-hosted Docker Compose stack for email security, mail hosting, encryption, and collaboration. It can sit in front of Microsoft 365, Google Workspace, Exchange, or Postfix, run as a full mail server, or combine those roles in a hybrid setup. Incoming mail passes through Postfix postscreen and RBL checks, followed by scanning orchestrated by Amavisd-new with SpamAssassin and ClamAV. Hermes checks SPF, signs and verifies DKIM, enforces and aggregates DMARC, and signs and verifies ARC. Encryption options include SMTP TLS, S/MIME, PGP, encrypted PDF fallback, and Dovecot mail-crypt at rest. Full-server mode adds Dovecot mailboxes, IMAPS, POP3S, Submission, LMTP, quotas, shared mailboxes, and Sieve rules. Bundled Nextcloud supplies file sync, webmail, calendars, and contacts; Authelia provides single sign-on and multi-factor options. The free Community Edition is open source. Pro costs $750.00 per year per server and has a free 30-day trial. Hermes requires a Linux host with Docker Engine 24.0 or later and Docker Compose v2.
Scrollout F1
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. The maker describes it for Linux and Windows administrators without advanced email security experience.
