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

impl is the scheduler (unix, lwt or async)
rdwr read/write syscall
flow witness of the flow (can be a socket)
ctx context used by the process
tls_config TLS configuration used by STARTTLS
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. It ensures to use STARTTLS (eg. RFC3207) while the process according TLS configuration tls_config. If authentication is given, it does the authentication only while TLS flow. Mail is sended only while TLS flow.

The stream mail must respects same assumptions as Sendmail_lwt.sendmail.
