fix: switch ratelimiter to MonotonicClock ( #167 )
...
There is a known bug that `quanta` clock
used by default sometimes jumps back:
<https://github.com/metrics-rs/quanta/issues/111 >.
This results in `governor` rate limiter
incorrectly rejecting the messages
even when less than the configured burst size
has been sent.
Switched to standard monotonic clock
which does not have this problem.
I tested that this fixed the problem for me,
chatmail relay test `test_exceed_rate_limit`
stopped failing randomly.

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
