is the server protected by TLS or SSL? or is it open? if SSL protected have you tried: p.put("mail.smtp.auth", "true"); p.put("mail.smtp.ssl.enable", "true");
Also have you tried loading Mail Session as a Resource in context.xml (or tomee.xml) as per my previous example? I didn't have much luck configuring it the way you are describing. Regards, Matthew -- Sent from: http://tomee-openejb.979440.n4.nabble.com/TomEE-Dev-f982480.html
