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.
