Open Source BSD Proxy Servers

The Anti-Spam SMTP Proxy (ASSP) Server project aims to create an open source platform-independent SMTP Proxy server which implements auto-whitelists, self learning Hidden-Markov-Model and/or Bayesian, Greylisting, DNSBL, DNSWL, URIBL, SPF, SRS, Backscatter, Virus scanning, attachment blocking, Senderbase and multiple other filter methods. Click 'Files' to download the professional version 2.8.1 build 24261. A linux(ubuntu 20.04 LTS) and a freeBSD 12.2 based ready to run OVA of ASSP V2 are also available for download. NOTICE: V1 development has been stopped at the end of 2014 (1.10.1 build 16060). Possibly there will be done some bugfixing in future. Please upgrade to V2, which is and will be actively maintained.

UFTP is an encrypted multicast file transfer program, designed to securely, reliably, and efficiently transfer files to multiple receivers simultaneously. This is useful for distributing large files to a large number of receivers, and is especially useful for data distribution over a satellite link (with two way communication), where the inherent delay makes any TCP based communication highly inefficient. The multicast encryption scheme is based on TLS with extensions to allow multiple receivers to share a common key. UFTP also has the capability to communicate over disjoint networks separated by one or more firewalls (NAT traversal) and without full end-to-end multicast capability (multicast tunneling) through the use of a UFTP proxy server. These proxies also provide scalability by aggregating responses from a group of receivers.

Caddy is a powerful, extensible, enterprise-ready server platform that uses TLS by default. Everything you would require in your infrastructure, from TLS certificate renewals and OCSP stapling, to reverse proxying and ingress, Caddy simplifies it all. Its modular architecture lets you do more with just a single static binary that compiles for any platform. Caddy is the only web server that uses HTTPS automatically and by default. It automatically renews TLS certificates, staples OCSP responses and more. Though used mostly as an HTTPS server, Caddy can be used to run Go applications, offering automated documentation, graceful on-line config changes via API and more to these apps. Caddy is very extensible, with a powerful plugin system unlike any other web server.
