The Kunena team has announce the arrival of Kunena 6.4.7[K 6.4.7] in stable which is now available for download as a native Joomla extension for J! 5.0.x/5.1.x/5.2.x/5.3.x/5.4.x. This version addresses most of the issues that were discovered in K 6.2 / K 6.3 / K 6.4 and issues discovered during the last development stages of K 6.4 Important note: Go to the Kunena Dashboard after an upgrade so that the Kunena database tables are also updated. This is particularly necessary for major version jumps so that the table changes are adapted.

All emails will be sent by the server which is in your local computer: 127.0.0.1. If you have this address in your server, it is misconfigured. Usually relays do not accept emails from this address, so it explains why emails are not sent to users.
I found the problem. My provider installed an accelerator for my website and it seams that there are 2 ways of getiing IP. One is local 127.0.0.1 and this one is used by kunena. The real ip is different.
