I'm confused. It's a standard github repository. And being git it doesn't matter too much where you clone from.
Browse changes, make a github fork etc: https://github.com/smtpd/qpsmtpd Clone over http: git clone https://github.com/smtpd/qpsmtpd.git Clone over git protocol: git clone git://github.com/smtpd/qpsmtpd.git If you for some reason never ever want to connect to a github server (or they are down), clone from git://git.develooper.com/qpsmtpd.git - ask
