Before, if `Config::FetchExistingMsgs` is set, existing messages were received with the `InSeen`
state set, but for bots they must be `InFresh` and also `IncomingMsg` events should be emitted for
them so that they are processed by bots as it happens with new messages.
Since commit c0a17df344
(PR https://github.com/deltachat/deltachat-core-rust/pull/3402)
`send_smtp_messages` returns an error
as soon as it encounters the first message it failed to send.
Since this worked like this for about 2 years
without any problems, there is no need to revert the change,
but outdated comment should be removed.
If a display name should be protected (i.e. opportunistically encrypted), only put the corresponding
address to the unprotected headers. We protect the From display name only for verified chats,
otherwise this would be incompatible with Thunderbird and K-9 who don't use display names from the
encrypted part. Still, we always protect To display names as compatibility seems less critical here.
When receiving a messge, overwrite the From display name but not the whole From field as that would
allow From forgery. For the To field we don't really care. Anyway as soon as we receive a message
from the user, the display name will be corrected.

Otherwise it's impossible to remove a member with missing key from a protected group. In the worst
case a removed member will be added back due to the group membership consistency algo.
The "I left the group" message can't be sent to a protected group if some member's key is missing,
in this case we should remain in the group. The problem should be fixed first, then the user may
retry to leave the group.
There was a comment in `fetch_existing_msgs()`: "Bots don't want those messages". If a bot doesn't
want this setting, why enable it? It's disabled by default anyway.
`IsChatmail` is set also by `inbox_fetch_idle()`, but it isn't called during `configure()`. Setting
`IsChatmail` from `inbox_fetch_idle()` is necessary to handle client/server upgrades, but
`IsChatmail` also should be available for the app after configuring an account, e.g. DC Android
needs it to know whether to ask the user to disable battery optimisations.
Before this fix LogSink was dropped immediately,
resulting in no logs printed for contexts created using
TextContext::new_alice(), but printed for contexts created
using TextContext::new().
`!to_ids().is_empty()` check is needed in cases of 1:1 chat creation
because otherwise `to_id` is undefined,
but in case of outgoing group message without recipients
observed on a second device creating a group should be allowed.
When doing an AEAP transition, we mustn't just delete the old peerstate as this would break
encryption to it. This is critical for non-verified groups -- if we can't encrypt to the old
address, we can't securely remove it from the group (to add the new one instead).
async-broadcast returns Overflowed error once
if channel overflow happened.
Public APIs such as get_next_event JSON-RPC method
are only expecting an error if the channel is closed,
so we should not propagate overflow error outside.
In particular, Delta Chat Desktop
stop receiving events completely if an error
is returned once.
If overflow happens, we should ignore it
and try again until we get an event or an error because
the channel is closed (in case of recv())
or empty (in case of try_recv()).
