Hi,
I tried to use the documentation for the Lamson (Inbound MTA). Sadly the website you are linking is gone the project is stalled for more than 4 years (see [[ https://github.com/zedshaw/lamson | GitHub ]]). There is a fork from the project which gets update regularly with name [[ https://github.com/moggers87/salmon | salmon ]]. Can you please change the documentation to reflect this?
Greetings,
Pouyan
