- add option to put messages in the queue "on hold", preventing delivery
attempts until taken off hold again.
- add "hold rules", to automatically mark some/all submitted messages as "on
hold", e.g. from a specific account or to a specific domain.
- add operation to "fail" a message, causing a DSN to be delivered to the
sender. previously we could only drop a message from the queue.
- update admin page & add new cli tools for these operations, with new
filtering rules for selecting the messages to operate on. in the admin
interface, add filtering and checkboxes to select a set of messages to operate
on.
it is a remnant from the time domains didn't have to be specific in
"Destination" addresses. we still use it for as default selection for adding a
new address to an account. but there's not much point in showing it so
prominently. that raises more questions than it is helpful.

we only have a "storage" limit. for total disk usage. we don't have a limit on
messages (count) or mailboxes (count). also not on total annotation size, but
we don't have support annotations at all at the moment.
we don't implement setquota. with rfc 9208 that's allowed. with the previous
quota rfc 2087 it wasn't.
the status command can now return "DELETED-STORAGE". which should be the disk
space that can be reclaimed by removing messages with the \Deleted flags.
however, it's not very likely clients set the \Deleted flag without expunging
the message immediately. we don't want to go through all messages to calculate
the sum of message sizes with the deleted flag. we also don't currently track
that in MailboxCount. so we just respond with "0". not compliant, but let's
wait until someone complains.
when returning quota information, it is not possible to give the current usage
when no limit is configured. clients implementing rfc 9208 should probably
conclude from the presence of QUOTA=RES-* capabilities (only in rfc 9208, not
in 2087) and the absence of those limits in quota responses (or the absence of
an untagged quota response at all) that a resource type doesn't have a limit.
thunderbird will claim there is no quota information when no limit was
configured, so we can probably conclude that it implements rfc 2087, but not
rfc 9208.
we now also show the usage & limit on the account page.

preventing writing out a domains.conf that is invalid and can't be parsed
again. this happens when the last address was removed from an account. just a
click in the admin web interface.
accounts without email address cannot log in.

by explaining (in the titles/hovers) what the concepts and requirements are, by
using selects/dropdowns or datalist suggestions where we have a known list, by
automatically suggesting a good account name, and putting the input fields in a
more sensible order.
based on issue #132 by ally9335
before, an error about an invalid address was not used, causing a delivery
attempt to an empty address (empty localpart/domain). delivery to that address
would fail, but we should've prevented that message from being queued at all.
additionally, an error in adding the message to the queue was ignored too.
an é (e with accent) can also be written as e+\u0301. the first form is NFC,
the second NFD. when logging in, we transform usernames (email addresses) to
NFC. so both forms will be accepted. if a client is using NFD, they can log
in too.
for passwords, we apply the PRECIS "opaquestring", which (despite the name)
transforms the value too: unicode spaces are replaced with ascii spaces. the
string is also normalized to NFC. PRECIS may reject confusing passwords when
you set a password.
both when parsing our configs, and for incoming on smtp or in messages.
so we properly compare things like é and e+accent as equal, and accept the
different encodings of that same address.
by mentioning the dnssec root keys, mentioning which unbound version has EDE,
giving a "dig" invocation to check for dnssec results.
based on issue #131 by romner-set, thanks for reporting
check the authentic data bit for the NS records of "com.", not for ".": some
dnssec-verifying resolvers return unauthentic data for ".".
for issue #139 by triatic, thanks!
