Javamail - Send mail over SSL
must send a mail use a SMTP with SSL.
This is an example of my code :
publicvoid sendMail(String destinatario,String mittente,String oggetto,String messaggio,String fileName,String fileNameInMail)throws Exception
{
if (protocol.equals("smtps")){
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
}
props=System.getProperties();
props.setProperty("mail."+protocol+".host", mailServer);
props.setProperty("mail.transport.protocol", protocol);
if (protocol.equals("smtps")){
props.setProperty("mail.smtps.auth","true");
props.setProperty("mail.smtps.starttls.enable","true");
props.setProperty("mail.smtps.socketFactory.fallback","false");
props.setProperty("mail.smtps.socketFactory.class", SSL_FACTORY);
props.setProperty("mail.smtps.socketFactory.port", UtilitaGenerale.getStringa(port));
}
Authenticator auth=null;
if(!mailUser.trim().equals(""))
auth=new MyAuthenticator(mailUser,mailPassword);
boolean debug =false;
//Session session = Session.getInstance(props,auth);
Session session=Session.getInstance(props,auth);
session.setDebug(true);
try{
Message msg =new MimeMessage(session);
Address mit=new InternetAddress(mittente);
msg.setFrom(mit);
InternetAddress[] address ={new InternetAddress(destinatario)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject(oggetto);
MimeBodyPart textPart =new MimeBodyPart();
textPart.setContent(messaggio,"text/plain");
MimeBodyPart attachFilePart =new MimeBodyPart();
FileDataSource fds =new FileDataSource(fileName);
attachFilePart.setDataHandler(new DataHandler(fds));
attachFilePart.setFileName(fileNameInMail);
Multipart mp =new MimeMultipart();
mp.addBodyPart(textPart);
mp.addBodyPart(attachFilePart);
msg.setContent(mp);
Transport transportTemp=null;
transportTemp= session.getTransport(protocol);
transportTemp.connect(mailServer,port,mailUser,mailPassword);
transportTemp.send(msg);
transportTemp.close();
}
catch(Exception e)
{
throw e;
}
finally
{
session=null;
}
}
but I obtain this error :

Your server is probably using a non-standard certificate, perhaps aself-signed certificate. The Java SSL support library (JSSE) isn't ableto verify the validity of such a certificate. See the SSLNOTES.txt fileincluded with JavaMail for tips on how to handle this.
# 2
I have been working on this exact problem, and am having no success.
I read the notes in SSLNotes.txt, and just for giggles, implemented the completely insecure example they provided (all certificates are trusted). And I get the following exception:
javax.mail.MessagingException: Could not connect to SMTP host: mail.xxxx.net, port: 465;
nested exception is:

There was a bug in the example code. The fix is described here: http://forum.java.sun.com/thread.jspa?forumID=43&threadID=740854

Thanks for that tip, that took care of the Unopened Socket problem. But ...
This is so weird, as it was working fine until we turned off mail-relay on the server I was using ... NOW the error is:

huh? I swear, this was working until I had to authenticate. Now I get a MIME type exception ...
Ideas? I have RTFMed, to no avail ...
# 5
Something is broken in your setup. Are you using the mail.jar file unmodified?
Have you changed your CLASSPATH setting?
JavaMail is unable to find the needed configuration files in the mail.jar file.
That's usually because you've modified mail.jar (e.g., by extracting all the
class files and putting them elsewhere) or because the ClassLoader you're
using in your environment is broken.
# 6
Yup, you were right, I hadnt properly updated the jar file ... I had removed much of the contents of the META-INF directory for various reasons. I put it all back, except the signatures, so I could self-sign the jars (because otherwise the various jars are signed by different certificates, and won't run under java WebStart). So that fixed that ... but caused something else ...

Which seems odd to me. I didn't delete anything down inside the javax.mail, etc. hierarchy, but now I get this exception.
I feel silly, since every fix finds another problem, but I'm stumped ...
# 7
Well, obviously you should compare the contents of your mail.jar filewith the original mail.jar file. Looks like you lost the "com" directory.
