SMTP server in Java

Im am currently writing a mail client in java, and want to implement this. However, i havn't got the faintest idea on where to begin. Any push in the right direction would be greatly appreciated!

Getting problem when connecting to SMTP server through java code

Hi all,
I am getting problem when i am going to connect with "Kerio SMTP server" through java code. The error what i am getting is :
"[16/Sep/2008 15:59:09] Sent: Queue-ID: 48cf8a73-000000f9, Recipient: <[email protected]>, Result: failed, Status: 5.3.2 554 5.0.0 Too many hops (101, max 100), message looping" when sending an email from [email protected]

Looks like something is set up wrong on your server that's causing messages
to be forwarded around a loop too many times without ever reaching the destination.
For instance, if server A forwards to server B, and server B forwards to server A,
this would happen.

Free SMTP server for Java mail testing

Hi all,
Are there any free SMTP servers that can be downloaded from the Net for Java mail. Thanks.
Regards
Ram

I am sorry ..may be my question was not very clear. I do not have am SMTP host. I need an SMTP host to route emails...is that possible.
If I have an SMTP host on my machine, then it will act as a router to route messages to other email severs like yahoo or hotmail.
So the "from" will be a user from the SMTP host.i.e my machine user and the "to" will be some email "[email protected]" or "[email protected]".
Is it posssible to route emails directly to any Yahoo or hotmail server using just java mail client?
Thanks

Start smtp server

Hi!
I am a beginner for JavaMail. I am following the tutorial of jGuru, 'Fundamnetals of JavaMail API'. I have done the following steps:
1. Downloaded JavaMail 1.3, set the classpath to mail.jar.
2. Downloaded JavaBeans Activation Framework and set classpath to activation.jar.
Now when I run the demo program: msgsendsample, I get the message of 'No SMTP server'
As there is one smtp.jar and also a pop3.jar file in the javamail/lib directory, I put them too into classpath. But putting SMTP.server value as localhost:25 does not help. Still i get the message of 'No SMTP server'.
Can anybody help me please on how to set up the smtp and pop servers coming along with javamail-1.3. I would like to avoid downloading another smtp server.
Thanks
Umesh

you need to specify a smtp server the java mail may use to send emails. somewhere in the code must be a variable called something like smtp server where you need to specify the smtp server. this should be an address like smtp.myprovider.com

How do i create a mail box in the SMTP server thru a java program

How do i create a mail box in the SMTP server thru a java program. If it is possible thru a java program.pls suggest a mail server compatible for the above possibility to work.
pls help ....

Please let me know if it is not at all possible to
create a user account automatically thru a program
(java) in a mail server... how does yahoo work
then..does he manually add a user to the mail
server...By talking to a web server not a mail server.
>
Is not there any mail server that will allow us to
create mailboxes for my java program.. how do the
other web account services work..
As I said mail servers do have management interfaces. You need to find one and then determine what the management interface is.

How do I connect to an SMTP server that requires a username and password?

Hi,
I am currently working on a project for university which requires me to send and receive email. I was until this week able to send mail no problem, but now the SMTP server has been upgraded so that each time a mail is sent it requires the username and password.
Ideally the connection should be made using TLS/SSL, and not use the Authenticator method. I want to pass the username and password directly if possible.
I've been trying to use the following but have been getting handshake, and other exceptions:
SMTPSSLTransport smtpSSLtransport = new SMTPSSLTransport(session,
                    new URLName("smtp", smtpHost, port, null-File,
                    "USERNAME", "PASSWORD"));
        smtpSSLtransport.setStartTLS(true);
        smtpSSLtransport.connect(new Socket(smtpHost, port));
        smtpSSLtransport.sendMessage(smtpMessage,                                                     message.getAllRecipients());
        smtpSSLtransport.close();Can anyone correct this piece of code for me or point me in the right direction of what classes and methods I should be using?
Many thanks in advance,
Gordon

I always wonder what misleads people to do things this way.
Was there some example you saw that suggested that instantiating
an SMTPSSLTransport was the correct approach? I hope not.
See the smtpsend.java demo program for how to use SMTP
authentication. If you need to use SSL, see the SSLNOTES.txt
file for hints on using the "smtps" protocol. smtpsend.java also
illustrates use of SSL, but you'll need to fix a bug in it to use the
correct property names ("mail.smtps.auth", etc.).

How to check whether a SMTP server is supporting Authentication or not

Hi All,
We are using Java Mail API 1.3.1/1.3.2 to send the messages. some of the SMTP servers that we use are supporting authentication and some of them are not.
As the SMTPTransport.supportsAuthentication() is not available only in Java mail API 1.4.1, we are identifying the SMTP server whether it is supporting authentication or not in the following way.
Socket clientSocket = null;
InetSocketAddress socketAddress = null;
OutputStream outStream = null;
InputStream inStream = null;
InputStreamReader inReader = null;
OutputStreamWriter outWritter = null;
try
clientSocket = new Socket();
socketAddress = new InetSocketAddress(host, port);
clientSocket.connect(socketAddress, timeout*1000); // convert timeout from second to miliseconds
// 1: now try to execute the given command by passing that on Out-Socket
outStream = clientSocket.getOutputStream();
outWritter = new OutputStreamWriter(outStream);
outWritter.write("ehlo localhost" +"\n");
outWritter.flush();
// 2:Read output of above command
inStream = clientSocket.getInputStream();
inReader = new InputStreamReader(inStream);
// This array limit would be fine to get "AUTH" extension of smtp server.
char[] arr = new char[16384];
StringBuilder strBuilder = new StringBuilder();
inReader.read(arr);
for(int i=0; i< arr.length; i++)
strBuilder.append(arr);
System.out.println(METHOD_NAME + "SMTP server response for ehlo localhost command ->"+strBuilder.toString());
// The output EHLO command comes like below :
// ehlo localhost
// 250-ap9058pc.us.oracle.com Hello ap614ses.us.oracle.com [130.35.33.43], pleased to meet you
// 250-ENHANCEDSTATUSCODES
// 250-PIPELINING
// 250-8BITMIME
// 250-SIZE
// 250-DSN
// 250-ETRN
// 250-AUTH GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN
// Since for XATUH ( like internal IP),
// we are not sure, so just checking for AUTH capability.
supported = strBuilder.indexOf("250-AUTH") >=0? true : false;
As shown in above code, we are issuing 'ehlo localhost' command to SMTP server, if the response i. 'strBuilder' contains '250-AUTH' then we are assuming that it is supporting authentication.
But for one SMTP server the 'strBuilder' value is showing as '220 mail.durofelguera.com ESMTP Service (Lotus Domino Release 8.5.2) ready at Thu, 16 Feb 2012 13:57:20 +0100' only which is socket connection output but not 'ehlo localhost' command output.
where as the telnet test output is showing correct only as below
# telnet mail.durofelguera.com 25
Trying 172.20.16.65...
Connected to mail.durofelguera.com.
Escape character is '^]'.
220 mail.durofelguera.com ESMTP Service (Lotus Domino Release 8.5.2) ready
at 0
ehlo localhost
250-mail.durofelguera.com Hello localhost ([172.20.15.209]), pleased to meet
yu
250-HELP
250-AUTH LOGIN
250-SIZE
250 PIPELINING
AUTH LOGIN
The question is why the 'strBuilder' is not showing 'ehlo localhost' conad output where as the telnet test results are showing correctly, what is going wrong here?
Is there any other way to check that whether SMTP server is supporting authentication or not?
Edited by: sarojak on Feb 19, 2012 10:11 PM

There are so many things wrong with your code, it's hard to know where to start...
Basically, the problem is not as simple as you think it is.
For example, some servers might not allow authentication until you've issued
the STARTTLS command.
These days, essentially all servers allow authentication. You're probably better
off just assuming the server supports.

Configuration error when saving SMTP server

I am configuring CUP 5.3 (SP06). When I put in our SMTP server, I get the following error:
" Action failed. An unknown error occurred while performing the operation. "
It looks like this screen was changed with SP06. I am not filling out anything under "Enter Email Notification Sender" or under "Application URL" (which seems to be new fields).

Hi Peggy,
This is a known bug in AC 5.3 SP6. SAP has added fields for administrator email address, application URL and redirection URL. Even though application URL and redirection URL do not show up as manadatory fields but they are required to save the configuration. To get pass through this error, just provide anything in those 2 textboxes with some dummy email address in administrator email address textbox. You should be able to save it now.
This is being fixed in SP7 which should release somewhere around end of March.

how can i do it using yahoo smtp server.
also i want to know whethr i can use that our smtp server from a computer outside of the net work.
pls help me
txs lot.

Almost certainly, if you are behind a proxy server it will only be a proxy for HTTP traffic, and you will not be able to communicate with an SMTP server outside your network. But you have your own SMTP server so why would you want to?
If you have a proxy server and an SMTP server then there will be people responsible for supporting them. Talk to those people and ask them to give you the basic explanation of networking that you need.

How to connect to my provider SMTP server?

hi,
i traying to connect to SMTP of my net provider, but i have problem like this:
DEBUG: setDebug: JavaMail version 1.4ea
DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc]
DEBUG SMTP: useEhlo true, useAuth false
DEBUG SMTP: trying to connect to host "mailhost", port 25, isSSL false
javax.mail.MessagingException: Unknown SMTP host: mailhost
e.getCause() = java.net.UnknownHostException: mailhost
HELP plz :/

The name of your "net provider" is probably not "mailhost".
Set the mail.smtp.host property to the name of the SMTP
server you want to connect to.
