Locally :

• go mod vendor
• docker build -f Dockerfile.dev -t smtp2http-dev .
• docker run -p 25:25 smtp2http-dev --timeout.read=50 --timeout.write=50 --webhook=http://some.hook/api

Or build it as it comes from the repo :

• docker build -t smtp2http .
• docker run -p 25:25 smtp2http --timeout.read=50 --timeout.write=50 --webhook=http://some.hook/api

The timeout options are of course optional but make it easier to test in local with telnet localhost 25 Here is a telnet example payload :

HELO zeus
# smtp answer

MAIL FROM:<email@from.com>
# smtp answer

RCPT TO:<youremail@example.com>
# smtp answer

DATA
your mail content
.
