When I try to send an Email via JAVAMAIL i get this error:
javax.mail.MessagingException: Can't send command to SMTP host;
nested exception is: Socket closed
javax.mail.MessagingException(java.lang.String, java.lang.Exception)
void com.sun.mail.smtp.SMTPTransport.sendCommand(java.lang.String)
void com.sun.mail.smtp.SMTPTransport.close()
void javax.mail.Transport.send0(javax.mail.Message, javax.mail.Address [])
void javax.mail.Transport.send(javax.mail.Message)
void de.hella.mailer.ejb.MailHelper.createAndSendMail(de.hella.mailer.ejb.EMailMessage)
void de.hella.mailer.ejb.MailerBean.sendMail(de.hella.mailer.ejb.EMailMessage)
void de.hella.mailer.ejb.EJSRemoteMailer.sendMail(de.hella.mailer.ejb.EMailMessage)
org.omg.CORBA.portable.OutputStream de.hella.mailer.ejb._EJSRemoteMailer_Tie._invoke(java.lang.String, org.omg.CORBA.portable.InputStream, org.omg.CORBA.portable.ResponseHandler)
What is the problem? Can anyone help me?`
Thanks a lot!

I am not familiar with your problem. I found this solution. I hope it can be of some help.

For JDK 1.2 the mailcap file has to go into jre/lib because that is the actual Java VM lib directory.

Try out by desabling TLS, the cause is that your mail server doesn't use TLS so I just disable it in your mail server like this properties.put("mail.smtp.starttls.enable","false") ;

I very much doubt that was the problem nine years ago. The idea of secured e-mail barely existed then and JavaMail certainly didn't support it.
I agree. Here's the link:

It's not a secret anymore!
