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.
* SC2068: Double quote array expansions to avoid re-splitting elements.
* 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'.
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.
* 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).

Extract new fingerprint from generation command output;
Verify that the generation has suceeded;
Verify that the current key fingerprint actually exists;
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.
roundcube Bug Fixes:
Fix for Cross-Site Scripting (XSS) via HTML messages with malicious CSS content
General Improvements from roundcube's Issue Tracker
This reverts commit b1d703a5e7 and adds python3-setuptools per the first version of #1899 which fixes an installation error for the b2sdk Python package.
v0.52 (January 31, 2021)
------------------------
Software updates:
* Upgraded Roundcube to version 1.4.10.
* Upgraded zpush to 2.6.1.
Mail:
* Incoming emails with SPF/DKIM/DMARC failures now get a higher spam score, and these messages are more likely to appear in the junk folder, since they are often spam/phishing.
* Fixed the MTA-STS policy file's line endings.
Control panel:
* A new Download button in the control panel's External DNS page can be used to download the required DNS records in zonefile format.
* Fixed the problem when the control panel would report DNS entries as Not Set by increasing a bind query limit.
* Fixed a control panel startup bug on some systems.
* Improved an error message on a DNS lookup timeout.
* A typo was fixed.
DNS:
* The TTL for NS records has been increased to 1 day to comply with some registrar requirements.
System:
* Nextcloud's photos, dashboard, and activity apps are disabled since we only support contacts and calendar.
