Mail-in-a-Box v0.17 Release Notes

Release Date: 2016-02-25 // about 8 years ago
  • Mail:

    • ⚡️ Roundcube updated to version 1.1.4.
    • ⚠ When there's a problem delivering an outgoing message, a new 'warning' bounce will come after 3 hours and the box will stop trying after 2 days (instead of 5).
    • On multi-homed machines, Postfix now binds to the right network interface when sending outbound mail so that SPF checks on the receiving end will pass.
    • Mail sent from addresses on subdomains of other domains hosted by this box would not be DKIM-signed and so would fail DMARC checks by recipients, since version v0.15.

    Control panel:

    • TLS certificate provisioning would crash if DNS propagation was in progress and a challenge failed; might have shown the wrong error when provisioning fails.
    • Backup times were displayed with the wrong time zone.
    • ⚠ Thresholds for displaying messages when the system is running low on memory have been reduced from 30% to 20% for a warning and from 15% to 10% for an error.
    • 🛠 Other minor fixes.

    System:

    • ⏪ Backups to some AWS S3 regions broke in version 0.15 because we reverted the version of boto. That's now fixed.
    • On low-usage systems, don't hold backups for quite so long by taking a full backup more often.
    • 🔧 Nightly status checks might fail on systems not configured with a default Unicode locale.
    • If domains need a TLS certificate and the user hasn't installed one yet using Let's Encrypt, the administrator would get a nightly email with weird interactive text asking them to agree to Let's Encrypt's ToS. Now just say that the provisioning can't be done automatically.
    • ⬇️ Reduce the number of background processes used by the management daemon to lower memory consumption.

    Setup:

    • The first screen now warns users not to install on a machine used for other things.
