I have fresh xwiki 12.1 with new version of JETTY. I configured mail by Administer wiki. When I try to send mail I get a message:
I use script Example 1 from
https://extensions.xwiki.org/xwiki/bin/view/Extension/Mail%20Sender%20API
Authentication works, becasuse if I provide wrong pass I get message
openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1)
OpenJDK 64-Bit Server VM (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1, mixed mode, sharing)
Any ideas how to configure mail?
