Re-order DS record algorithms by digest type and revise warning message (#2002) 2021-08-22 14:45:56 -04:00
Joshua Tauberer 67b5711c68 Recommend that DS records be updated to not use SHA1 and exclude MUST NOT methods (SHA1) and the unlikely option RSASHA1-NSEC3-SHA1 (7) + SHA-384 (4) from the DS record suggestions 2021-08-22 14:43:46 -04:00
myfirstnameispaul 20ccda8710 Re-order DS record algorithms by digest type and revise warning message.
Note that 7, 4 is printed last in the status checks page but does not appear in the file, and I couldn't figure out why.

fail2ban now supports ipv6 (#2015)
Since fail2ban 0.10.0, ipv6 support has been added. The current Ubuntu 18.04 repository has fail2ban 0.10.2, which does have ipv6 protection.

Ignore bad encoding in email addresses when parsing maillog files (#2017)
local/domain parts of email address should be standard ASCII or
UTF-8. Some email addresses contain extended ASCII, leading to
decode failure by the UTF-8 codec (and thus failure of the
Usage-Report script)

This change allows maillog parsing to continue over lines
containing such addresses

Joshua Tauberer d510c8ae2a Enable and recommend port 465 for mail submission instead of port 587 (fixes #1849)
Port 465 with "implicit" (i.e. always-on) TLS is a more secure approach than port 587 with explicit (i.e. optional and only on with STARTTLS). Although we reject credentials on port 587 without STARTTLS, by that point credentials have already been sent.

Joshua Tauberer e283a12047 Add null SPF, DMARC, and MX records for automatically generated autoconfig, autodiscover, and mta-sts subdomains; add null MX records for custom A-record subdomains
All A/AAAA-resolvable domains that don't send or receive mail should have these null records.

This simplifies the handling of domains a bit by handling automatically generated subdomains more like other domains.

* SC2186: tempfile is deprecated. Use mktemp instead.
* SC2124: Assigning an array to a string! Assign as array, or use * instead of @ to concatenate.
* SC2102: Ranges can only match single chars (mentioned due to duplicates).
* SC2005: Useless echo? Instead of 'echo $(cmd)', just use 'cmd'.

Joshua Tauberer 2c295bcafd Upgrade the Roundcube persistent login cookie encryption to AES-256-CBC and increase the key length accordingly
This change will force everyone to be logged out of Roundcube since the encryption key and cipher won't match anyone's already-set cookie, but this happens anyway after every Mail-in-a-Box update since we generate a new key each time already.

Fixes #1968.

Joshua Tauberer 178c587654 Migrate to the ECDSAP256SHA256 (13) DNSSEC algorithm
* Stop generating RSASHA1-NSEC3-SHA1 keys on new installs since it is no longer recommended, but preserve the key on existing installs so that we continue to sign zones with existing keys to retain the chain of trust with existing DS records.
* Start generating ECDSAP256SHA256 keys during setup, the current best practice (in addition to RSASHA256 which is also ok). See https://www.iana.org/assignments/dns-sec-alg-numbers/dns-sec-alg-numbers.xhtml#dns-sec-alg-numbers-1 and https://www.cloudflare.com/dns/dnssec/ecdsa-and-dnssec/.
* Sign zones using all available keys rather than choosing just one based on the TLD to enable rotation/migration to the new key and to give the user some options since not every registrar/TLD supports every algorithm.
* Allow a user to drop a key from signing specific domains using DOMAINS= in our key configuration file. Signing the zones with extraneous keys may increase the size of DNS responses, which isn't ideal, although I don't know if this is a problem in practice. (Although a user can delete the RSASHA1-NSEC3-SHA1 key file, the other keys will be re-generated on upgrade.)
* When generating zonefiles, add a hash of all of the DNSSEC signing keys so that when the keys change the zone is definitely regenerated and re-signed.
* In status checks, if DNSSEC is not active (or not valid), offer to use all of the keys that have been generated (for RSASHA1-NSEC3-SHA1 on existing installs, RSASHA256, and now ECDSAP256SHA256) with all digest types, since not all registers support everything, but list them in an order that guides users to the best practice.
* In status checks, if the deployed DS record doesn't use a ECDSAP256SHA256 key, prompt the user to update their DS record.
* In status checks, if multiple DS records are set, only fail if none are valid. If some use ECDSAP256SHA256 and some don't, remind the user to delete the DS records that don't.
* Don't fail if the DS record uses the SHA384 digest (by pre-generating a DS record with that digest type) but don't recommend it because it is not in the IANA mandatory list yet (https://www.iana.org/assignments/ds-rr-types/ds-rr-types.xhtml).

Enable sending DMARC failure reports (#1929)
Configures opendmarc to send failure reports for domains that request them, including when p=none.

The emails are sent as the package default of package name and user@hostname: OpenDMARC Filter <opendmarc@box.example.com>

Note I have been running this for several months with a configuration I did not include in the PR to have reports BCC'd to me (FailureReportsBcc postmaster@example.com). Very low load for my personal server of rarely more than a dozen emails sent out per day.

I am not familiar with editing scripts, so apologies in advance and please feel free to correct me.
