[EMAIL] Using Apache Commons Email and Google
Dear All,
I was trying to use the Commons Email project for sending email with
the Google provider, but I failed. I tried with the following code
SimpleEmail email = new SimpleEmail();
email.setDebug(true);
email.addTo(MAIL_DESTINATION, "Stefano Lenzi");
email.setFrom(MAIL_SENDER, "Test");
email.setSubject("Test message");
email.setMsg("This is a simple test of commons-email");
email.setHostName(SMTP_HOST_NAME);
email.setAuthentication(SMTP_AUTH_USER, SMTP_AUTH_PWD);
email.setTLS(true);
email.setSmtpPort(SMTP_HOST_PORT);
email.send();
but nothing happened. Here is the debug shown DEBUG: JavaMail version
1.4.1ea-SNAPSHOT

I believe that the problem is that the protocol chosen is "smtp" while
it should be "smpts". In fact, I have later tryed the code available
here:
http://www.rgagnon.com/javadetails/java-0570.html
the it worked perfectly, and the two difference are the protocol
chosen for sending the email and the way the transport is initialized.
Is it a bug in Commons Email, or am I doing something wrong?
Ciao,

Hi Jason,
thanks for the hint, but are you sure that this is working correctly?
Looking at the Transport.send(Message msg, Address[] addresses) javadoc,
it states the following:
* Send the message to the specified addresses, ignoring any
* recipients specified in the message itself.
Thus when calling it with the from address, it will only be sent to the
originator of the message and not to the actual recipients.
Furthermore, the code does not compile as there is no overloaded send
method which takes a String as third argument (and there is no implicit
conversion to an Address).

Resurrecting this old post, I found that in order to Authenticate with SASL
using
https://code.google.com/p/google-mail-oauth2-tools/source/browse/#svn%2Ftrunk%2Fjava%2Fcom%2Fgoogle%2Fcode%2Fsamples%2Foauth2
it was necessary to invoke
Transport.send(this.message, this.getFromAddress().getAddress(), "");
rather than
Transport.send(this.message);
The attached patch does this. The if condition may need to be tweaked to
make it more specific to google-mail-oauth2.
cheers .. Jason

Hmm... are you sure?
AFAIK, STARTTLS promotes a plain connection to an encrypted one, irrespectively of any authentication mechanisms:
http://en.wikipedia.org/wiki/STARTTLS
Once a connection is upgraded, it stays encrypted.
Perhaps you are referring to SASL, which deals with authentication?
One way or another, way too many acronyms :D

Hmm... that's strange. I thought javamail would read system properties
as well as those set directly using a java.util.Properties object, but
maybe it doesn't. Commons-email doesn't appear to give you the option of
setting javamail properties directly, but it does allow you to set the
javamail session like this:
Properties props = new Properties();
props.put("mail.transport.protocol", "smtps");
...
Session session = Session.getDefaultInstance(props);
...
email.setMailSession(session);
email.send();
This should allow you to set properties such as mail.debug,
mail.transport.protocol, etc.

I don't find anything strange about the above log message, do you?
> "DEBUG SMTP: trying to connect to host "smtp.gmail.com", port 465, isSSL false"
Now /that/ is strange if you have set SSL=true. Perhaps there's a bug in
the debug logging.
I have found that commons-email acts strangely in a number of
circumstances. I unfortunately had to abandon its use a while back in
order to be able to send attachments along with text *and* HTML email
messages. I wrote my own wrapper with what I believe is a simpler API.

Even the -Dmail.transport.protocol=smtps system property didn't
change anything, it looks like that the system properties are not used

Try setting -Dmail.debug=true and run it again. This will give you much
more output from Javamail.
It's unclear from the javadoc, but it's possible that setTLS(true)
merely configures Javamail to use STARTTLS over a plaintext SMTP
connection. If you want to use SMTPS, try setting
- -Dmail.transport.protocol=smtps to see if that helps.
> DEBUG SMTP: trying to connect to host "smtp.gmail.com", port 465, isSSL false
See that SSL=false. If you want SSL, use setSSL(true) instead of
setTLS(true).
I'm not sure what gmail prefers and/or requires, but generally
STARTTLS-over-SMTP will give you better performance, because only the
authentication is encrypted and not the entire SMTP conversation.
> http://www.rgagnon.com/javadetails/java-0570.html
That page indicates that GMail requires SSL, not TLS. Try changing
setTLS(true) to setSSL(true) and see if that works.
Hope that helps,
