people will either paste the records in their zone file. in that case, the
records will inherit "IN" from earlier records, and there will always be one
record. if anyone uses a different class, their smart enough to know they need
to add IN manually.
plenty of people will add their records through some clunky web interface of
their dns operator. they probably won't even have the choice to set the class,
it'll always be IN.
the vendored dns resolver code is a copy of the go stdlib dns resolver, with
awareness of the "authentic data" (i.e. dnssec secure) added, as well as support
for enhanced dns errors, and looking up tlsa records (for dane). ideally it
would be upstreamed, but the chances seem slim.
dnssec-awareness is added to all packages, e.g. spf, dkim, dmarc, iprev. their
dnssec status is added to the Received message headers for incoming email.
but the main reason to add dnssec was for implementing dane. with dane, the
verification of tls certificates can be done through certificates/public keys
published in dns (in the tlsa records). this only makes sense (is trustworthy)
if those dns records can be verified to be authentic.
mox now applies dane to delivering messages over smtp. mox already implemented
mta-sts for webpki/pkix-verification of certificates against the (large) pool
of CA's, and still enforces those policies when present. but it now also checks
for dane records, and will verify those if present. if dane and mta-sts are
both absent, the regular opportunistic tls with starttls is still done. and the
fallback to plaintext is also still done.
mox also makes it easy to setup dane for incoming deliveries, so other servers
can deliver with dane tls certificate verification. the quickstart now
generates private keys that are used when requesting certificates with acme.
the private keys are pre-generated because they must be static and known during
setup, because their public keys must be published in tlsa records in dns.
autocert would generate private keys on its own, so had to be forked to add the
option to provide the private key when requesting a new certificate. hopefully
upstream will accept the change and we can drop the fork.
with this change, using the quickstart to setup a new mox instance, the checks
at internet.nl result in a 100% score, provided the domain is dnssec-signed and
the network doesn't have any issues.
for issue #71 reported by naturalethic, thanks!
users upgrading from v0.0.6 to v0.0.7 could run into this. the release notes
have been updated with a link to the issue. the issue will stay open until at
least the next release.
in verifydata, when warning about missing threading, print the db file.
otherwise it isn't clear which account this is about
when upgrading account thread storage, pass the logger that has the account
name.
even if not asked for with the "return (special-use)" extended list parameter.
macos x mail does not request the special-use flags, but will use them when present.
for issue #66, thanks x8x for providing the imap protocol transcript that
showed how it is done!
because with the name you would expect an account name.
and the email-resolving behaviour is surprising: with wildcard addresses you
can use any address, including a typo. you would change the password of the
address with the wildcard, without any warning. accounts are more precise and
less error-prone.
for issue #68 by x8x
we set the flag both for move in imap and in webmail.
this also ensures the "MailboxDestinedID", used for per-mailbox reputation
analysis, is set in more reject-situations. before this change, some rejects
(such as based on DMARC reject) wouldn't result in reputation being used after
having been moved the message out of the rejects mailbox.
in the future, we need more tests for scenario's like this...
for issue #63 reported by x8x
may also help with issue #64
removing an item from the selected list should be done regardless of focus,
i.e. the code snippet shouldn't have been behind the "if (focus...)" condition.
for the path from v0.0.5 with lots of messages straight to the latest
development version. this can do multiple database changes in one go, so it's a
bit different than for installs where an admin has upgraded each version when
it was released.
we want to user to submit the stack trace. user can still edit before
submitting, but it won't look attractive to submit stacktraces with info that
shouldn't be there. not great that firefox is including too much info and the
effort we need to make to get it out again, but well.
increase() and rate() don't seem to assume a previous value of 0 when a vector
gets a first value for a label. you would think that an increase() on a
first-value mox_panic_total{"..."}=1 would return 1, and similar for rate(), but
that doesn't appear to be the behaviour. so we just explicitly initialize the
count to 0 for each possible label value. mox has more vector metrics, but
panics feels like the most important, and it's too much code to initialize them
all, for all combinations of label values. there is probably a better way that
fixes this for all cases...
we match messages to their parents based on the "references" and "in-reply-to"
headers (requiring the same base subject), and in absense of those headers we
also by only base subject (against messages received max 4 weeks ago).
we store a threadid with messages. all messages in a thread have the same
threadid. messages also have a "thread parent ids", which holds all id's of
parent messages up to the thread root. then there is "thread missing link",
which is set when a referenced immediate parent wasn't found (but possibly
earlier ancestors can still be found and will be in thread parent ids".
threads can be muted: newly delivered messages are automatically marked as
read/seen. threads can be marked as collapsed: if set, the webmail collapses
the thread to a single item in the basic threading view (default is to expand
threads). the muted and collapsed fields are copied from their parent on
message delivery.
the threading is implemented in the webmail. the non-threading mode still works
as before. the new default threading mode "unread" automatically expands only
the threads with at least one unread (not seen) meessage. the basic threading
mode "on" expands all threads except when explicitly collapsed (as saved in the
thread collapsed field). new shortcuts for navigation/interaction threads have
been added, e.g. go to previous/next thread root, toggle collapse/expand of
thread (or double click), toggle mute of thread. some previous shortcuts have
changed, see the help for details.
the message threading are added with an explicit account upgrade step,
automatically started when an account is opened. the upgrade is done in the
background because it will take too long for large mailboxes to block account
operations. the upgrade takes two steps: 1. updating all message records in the
database to add a normalized message-id and thread base subject (with "re:",
"fwd:" and several other schemes stripped). 2. going through all messages in
the database again, reading the "references" and "in-reply-to" headers from
disk, and matching against their parents. this second step is also done at the
end of each import of mbox/maildir mailboxes. new deliveries are matched
immediately against other existing messages, currently no attempt is made to
rematch previously delivered messages (which could be useful for related
messages being delivered out of order).
the threading is not yet exposed over imap.
this is a problem for connections like SSE, that only send data on events.
those events would stay in the gzip buffer until lots more data was written.
bug because of automatically typing "if err != nil"...
found while testing the maildir/mbox web-based import while working on message
threading support. the import gets progress SSE events that were now hanging.
