A new version of Dovecot has been released, I’ve installed it on my test servers and production server without a problem. I would advise you to upgrade this time as the SSL stuff is recommended to be used. The noticeable changes are:

  • Proxying now supports sending SSL client certificate to server with ssl_client_cert/key settings.
  • doveadm dump: Added support for dumping dbox headers/metadata.
  • Fixed memory leaks in login processes with SSL connections
  • vpopmail support was broken in v2.0.16
