Boa tarde

Estou utilizando javamail para realizar operações de envio de e-mails, meu problema é que na minha maquina local funciona, mas quando coloco a aplicação no servidor estou recebendo a seguinte exception:

tion: Can't send command to SMTP host;cat-6.0.24/logs$ javax.mail.MessagingExcep   nested exception is:
