Hi! I also tried that but that the output debug: | 11:56:22,968 INFO [MailSession] Creating JavaMail Session (out.virgilio.it:25) | 11:56:22,968 INFO [STDOUT] DEBUG: setDebug: JavaMail version 1.4ea | 11:56:22,968 INFO [MailSession] connected to mail server | btw I don't think it is a JavaMail problem...I also use JavaMail in another Java program and it works from my workstation with the same settings...
