| Fact | Hermes Secure Email Gateway | Scrollout F1 |
|---|---|---|
| Deployment | It can run as a gateway in front of Microsoft 365, Google Workspace, Exchange, or Postfix, as a full mail server, or in hybrid mode. | The maker says basic deployment involves two configuration steps and is designed to be ready within 30 minutes. |
| Encryption | Hermes supports SMTP TLS, S/MIME, PGP, encrypted-PDF fallback and Dovecot mail-crypt encryption at rest. | The maker lists TLS 1.2 and an option to enforce encrypted connections with email servers. |
| Filtering | Inbound mail passes through Postfix postscreen and RBL checks, then Amavisd-new orchestrates SpamAssassin and ClamAV scanning. | The maker lists protection against executable files, malicious content, scripts, forged domains, and invalid or unknown hosts. |
| Support | Community support is informal through GitHub forums, the issue tracker, Matrix, and Telegram; direct vendor support requires eligible Pro support coverage or purchased incidents. | The project’s support page identifies its Discussion forum as the best way to get help. |
