Hi Dave, thank you very much for your reply. I've been trying a few hours now and found the mistakes. My installation is working now!
One of the mistakes is a JSPWiki bug. For now, I believe no one could have been using JSPWiki mailing via JNDI as it's been simply logically impossible. Dave, I found your JIRA entry on this issue and will reopen it and post the solution as a comment there. There are a few other hints related to JavaMail in general. Maybe you and me could write a bit about this on jspwiki.org? Regards, Florian
