This release fixes TLS interoperability with incoming deliveries from Microsoft servers by disabling TLS session tickets. If you have MTA-STS and/or DANE enabled, TLS is required for successful delivery, and updating to v0.0.13 is required to receive messages from Microsoft again. TLS session tickets may be enabled again in a future release, possibly per port/service.

Improvements

• In the IMAP server, for the "bodystructure" response item to a "FETCH" command, add the content-type parameters for multiparts so IMAP clients will get the MIME boundary without having to parse the message themselves. (issue [#217], 8fa197b19dfe)
• Add an HTTP handler for the acme http-01 validiation mechanism to all plain http (non-tls) webservers (ports), not only to the one listening on port 80. (#issue 218, 0fbf24160c65)
• Properly link to matrix room so users can find it. (issue [#226], 76f7b9ebf64c)

Bug fixes

• Disable session tickets for tls to workaround deliverability issues with incoming email from Microsoft over smtp with starttls. Without this fix, email from Microsoft is no long coming in. (issue [#237], 22c8911bf3f7)
• In the SMTP server, when logging about problems with recipients, actually show which recipients were present in the session. (issue [#232], 598c5ea6ac9f).
• Webmail: During "send and archive", don't fail with error message when message that is being responded to is already in archive folder. (issue [#233], 879477a01f72)
• Webmail: if we don't have loaded account settings yet, abort loading the popup after showing an error that the settings aren't available yet. (issue [#218], 04305722a783)

Update instructions

Before upgrading, do a dry-run first.

• Make a temporary backup with the old mox version: mox-v0.0.12 backup data/tmp/testupgrade
• Verify that all is well with the old version: mox-v0.0.12 verifydata data/tmp/testupgrade
• Verify the state with the new version: mox-v0.0.13 verifydata data/tmp/testupgrade

With a successful dry-run, the upgrade should go smoothly. Make a new backup with mox-v0.0.12 backup data/tmp/backup (the previous backup was modified by the dry-run, so couldn't be used to restore!), replace the binary and restart.

If you run into any problems, please create a bug report.
