smtp-client-simple

A very simple exposure of a given smtp-servers protocol through http.

The api accepts no path variables. Only query parameters: from, to(one or more).

The server additionally takes subject and msg query parameters. And will add any http body content, as the email body.

##example usage (caller side):

curl 'some-host:<port>?to=[e-mail]&[e-mail]&from=[e-mail]&msg=some%20body&subject=Hello%20World'

with message from file:

$ cat <<EOF > message
Subject: whatever you want

body after two linebreaks
EOF
$ curl some-host:<port>?to=[e-mail] --data-binary @message

usage docker for a server exposing the smtp-server smtp.my.domain.com:25 without tls from the port 12345, always sending from the mail [e-mail]

docker run --rm -d -p 8080:12345 mjuul/smtp-client-simple --port 12345 --smtp-server smtp.my.domain.com:25 --forced-from [e-mail] --skip-tls

get help text

docker run mjuul/smtp-client-simple --help

the server allows configuration of default fallbacks for, body, subject, to(plural via comma-separation) and from.

use case

I use it in pipelines exposing an internal smtp-server. For custom notifications.

TODO

• insecure / log-in - including a locked address?
