Yaguareté (panthera onca)


chasquid is an SMTP (email) server with a focus on simplicity, security, and ease of operation.

It's written in Go, and is open source under the Apache license 2.0.

It is currently in beta: it's functional and has had some production exposure, but some things may still change in backwards-incompatible ways, including the configuration format. It should be rare and will be avoided if possible.



The Debian+Dovecot+chasquid how-to and the installation guide are the best starting points on how to install, configure and run chasquid.

You can also check out the manual pages for more details on daemon invocation and configuration.
