sendmail impl rdwr flow ctx ?authentication ~domain sender recipients mail where:

impl is the scheduler (unix, lwt or async)
rdwr read/write syscalls
flow witness of the flow (can be a socket)
ctx context used by the process
authentication authentication information used by the process
sender sender of the mail
recipients recipients of the mail
mail stream of the mail

This process try to send a mail according RFC4409. The process should be wrapped into a secured flow (like TLS). For a real use-case of sendmail, you should look into sendmail-lwt which takes care about the TLS layer.
