smtp2http is a simple smtp server that resends the incoming email to the configured web endpoint (webhook) as a basic http post request.
go mod vendorgo build
Locally :
go mod vendordocker 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
.
Docker images arn't available online for now See "Dev with Docker" above
docker run -p 25:25 smtp2http --webhook=http://some.hook/api
smtp2http --listen=:25 --webhook=http://localhost:8080/api/smtp-hook
smtp2http --help
