SMTP2HTTP (email-to-web)

Dev
go mod vendorgo build
Dev with Docker
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 protected]>
# smtp answer
RCPT TO:<[email protected]>
# smtp answer
DATA
your mail content
.
