bstore was updated to v0.0.6 to add this logging.
this simplifies some of the db-handling code in mtastsdb,tlsrptdb,dmarcdb. we
now call the package-level Init() and Close() in all tests properly.
the stuttering was introduced to make the same type name declared in multiple
packages, and used in the admin sherpa api, unique. with sherpadoc's new
rename, we can make them unique when generating the api definition/docs, and
the Go code can use nicer names.
embarrassingly, we didn't accept all reports we generated. after the changed
handling of reports about mx/mail host vs recipient domains, would send reports
to mail hosts about multiple recipient domains + the mail host. and we included
a policy domain of the mail host when sending to a recipient domain. we were
still being strict in what we accepted: only a single domain in total in the
entire report, and we still enforced that a report sent to the mx host tlsrpt
address only contained the mx host as policy domain. and likewise for recipient
domains and their tls reporting addresses. those checks would reject reports
generated by a mox instance. this probably only happens with dane configured,
probably most users haven't seen it because of that.
somewhat related to issue #125
we don't want external software to include internal details like mlog.
slog.Logger is/will be the standard.
we still have mlog for its helper functions, and its handler that logs in
concise logfmt used by mox.
packages that are not meant for reuse still pass around mlog.Log for
convenience.
we use golang.org/x/exp/slog because we also support the previous Go toolchain
version. with the next Go release, we'll switch to the builtin slog.
- accept incoming tls reports for the host, with policy-domain the host name.
instead of not storing the domain because it is not a configured (recipient)
domain.
- in tlsrpt summaries, rename domain to policy domain for clarity.
- in webadmin, fix html for table that lists tls reports in case of multiple
policies and/or multiple failure details.
we were already accepting, processing and displaying incoming tls reports. now
we start tracking TLS connection and security-policy-related errors for
outgoing message deliveries as well. we send reports once a day, to the
reporting addresses specified in TLSRPT records (rua) of a policy domain. these
reports are about MTA-STS policies and/or DANE policies, and about
STARTTLS-related failures.
sending reports is enabled by default, but can be disabled through setting
NoOutgoingTLSReports in mox.conf.
only at the end of the implementation process came the realization that the
TLSRPT policy domain for DANE (MX) hosts are separate from the TLSRPT policy
for the recipient domain, and that MTA-STS and DANE TLS/policy results are
typically delivered in separate reports. so MX hosts need their own TLSRPT
policies.
config for the per-host TLSRPT policy should be added to mox.conf for existing
installs, in field HostTLSRPT. it is automatically configured by quickstart for
new installs. with a HostTLSRPT config, the "dns records" and "dns check" admin
pages now suggest the per-host TLSRPT record. by creating that record, you're
requesting TLS reports about your MX host.
gathering all the TLS/policy results is somewhat tricky. the tentacles go
throughout the code. the positive result is that the TLS/policy-related code
had to be cleaned up a bit. for example, the smtpclient TLS modes now reflect
reality better, with independent settings about whether PKIX and/or DANE
verification has to be done, and/or whether verification errors have to be
ignored (e.g. for tls-required: no header). also, cached mtasts policies of
mode "none" are now cleaned up once the MTA-STS DNS record goes away.
