Hallo Christian, I've taken a deeper look at mail configuration in web applications recently in the context of JSPWiki. Have a look at http://www.jspwiki.org/wiki/JNDI%20Mail%20Configuration
Especially: > Note if you're using an SMTP mail server that requires > authentication: This won't work if only mail.user and mail.password > are set because these aren't automatically used for authentication. > Therefore, you have to set username and password to the same values > (or other values that authenticate you properly). For details see > http://forum.java.sun.com/thread.jspa?threadID=615393&messageID=3422166 Since you're getting an AuthenticationFailedException, I'm pretty sure that's it. I've been testing this with a mail server from 1&1. Regards, Florian
