On FreeBSD 127.0.0.2 is not assigned to any interface by default,
so 127.0.0.2 source address hack cannot be used to make OpenDKIM
verify the signature instead of signing.
This change sets InternalHosts to `-` so no IP addresses
make OpenDKIM sign the message. Instead of IP address,
OpenDKIM in the outgoing pipeline is explicitly told
to sign messages by setting `{daemon_name}` macro to `ORIGINATING`.
Stalwart sends `NOTIFY=DELAY,FAILURE`
to request Delivery Status Notifications.
aiosmtpd does not support any parameters,
not just ORCPT, so we have to ignore all of them.
- username_min_length and username_max_length are both set to a
default value of 9 in the chatmail.ini.f template. When they have
the same value, it doesn't matter which one we use in newemail.py
(which handles the /new URL). However, if they are configured to
different values by the admin, then the current implementation using
username_min_length chooses from a smaller set of possible
usernames.
- Revised create_newemail_dict() in newemail.py to use
username_max_length as the length of the random username it offers
via the /new URL. This randomizes within a much larger set of
possible usernames.

`authclean` cleanup server is used by
reinjecting smtpd running on localhost:10025 by default.
It runs after filtermail
and currently removes `Received` header
to avoid leaking IP address.
Can as well be used to replace `Subject` lines
with `Subject: [...]`.
If there are multiple `Subject` lines,
all of them should be replaced.
This allows us to avoid dealing with
localized subjects, including SecureJoin
messages `vc-request` and `vg-request`
which can have Subject lines like
Subject: =?utf-8?q?Nachricht_von_nrn178fi4=40nine=2Etestrun=2Eorg?=
