Jagoda Estera Ślązak cf64778f71 feat(transport): Remote delivery over SMTP (#104) ...

Implements a new mode "transport",
that allows filtermail to be used for
remote delivery.

In transport mode, filtermail listens for LMTP
connections, splits messages by domain
and performs delivery to remote MTAs over SMTP.

SMTP client tries to open socket on all resolved
addresses in parallel and uses one that succeeds
the first, fixing the issue described in:
chatmail/relay#900

Extends the built-in SMTP client
with STARTTLS support.

Extends the built-in SMTP server
with LMTP greeting support.

Groundwork required for mxdeliv endpoint
(HTTP channel for MTA-to-MTA communication):
chatmail/relay#900
