v5.1.4 Released

email spam filter server

v5.1.4

Service Changes

  • Mailborder now uses its own native SPF evaluation engine. The new engine does a better job at evaluating newer SPF records with wildcard formats. It is set to sane values out of the box. The configuration file with the settings is here: /etc/mailborder/spf.cf but put your edits in /etc/mailborder/conf.d/spf.cf
  • You can now add custom Postfix smtpd_milters by editing the file /etc/mailborder/conf.d/postfix.cf and adding them to the appropriate line. Your custom milters will be added after the Mailborder DKIM and DMARC evaluation during configuration rebuilds.
  • An automatic ClamAV fix was added. As many people found out, there is a change between Ubuntu 16 and 18 with systemd which would cause ClamAV to fail and email would stop being processed. This automatic fix checks for the right settings and autocorrects them. A server suffering from this will need to be rebooted for the changes to take effect. This check will automatically run every time Mailborder is upgraded. It can be manually executed with the command: mb-os-check -r as the root user or with sudo.

 

Ubuntu 20.04 LTS

This upgrade can easily take an hour on a fast connection. Plan accordingly.

To upgrade from Ubuntu 18.04 to 20.04:

  • First, upgrade to the latest version of Mailborder as shown above.
  • Take a snapshot or full backup of some kind.
  • Edit /etc/apt/sources.list and change the bionic reference to focal for the Mailborder repository. (deb.mailborder.com) Do this after upgrading to the latest version of Mailborder and before running the next step.
  • Run as root: do-release-upgrade --allow-third-party
  • Select the default option to keep everything except /etc/apparmor.d/usr.sbin.clamd which needs to be replaced with the new version.
  • If you need or want help, contact Mailborder support.

Performance Notes

Some major performance enhancements are included with this update in regard to scanning speed with this release. DNS checks slow scanning speed on Mailborder servers. Mailborder server configurations have been updated to find and use Razor and Pyzor DNS services that are closer in geographical location and faster in replies. This typically results in spam scanning that is 4 to 8 times faster than the previous model for Mailborder customers outside of the United States. This also improves spam scanning speed for customers within the United States that is 2 to 4 times faster.

Spamassassin has also been modified to use the local caching DNS server at 127.0.0.1 that runs on all Mailborder servers regardless of the server's network configuration. This will also provide moderate to extreme scanning speed increases depending on each server's network and location.
