About EmailRelay
EmailRelay is a lightweight SMTP server that runs on Windows and Unix systems. It handles email relaying, delivery, and forwarding with a small footprint. The software includes built-in spam filtering using DNS blacklists and content rules.
You can configure it as a mail relay for your network or as a local delivery agent. It supports SMTP authentication, TLS encryption, and routing based on domains. The server integrates with existing mail systems and can forward messages to external providers like Gmail or Office 365. It also provides a web interface for monitoring.
This tool is useful for system administrators who need a simple, reliable SMTP relay without the overhead of full mail servers like Postfix or Exchange. It is released under the GNU General Public License, free to use and modify. The project has been maintained since 2004 and is available via SourceForge.
