simple SMTP (email) server written in go
chasquid is an SMTP (email) server. It aims to be easy to configure and maintain for a small mail server, at the expense of flexibility and functionality. . 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.
