Java Mail Server

Is there a way to write a POP and SMTP server with java?

Java? Yes, and several people have done so. See the [JavaMail FAQ|http://java.sun.com/products/javamail/FAQ.html] and [Third Party Products|http://java.sun.com/products/javamail/Third_Party.html] list.
JavaMail? Only sort of.

James - Java Mail Server

I would really appreciate any help or support from the forum on the
follwing queries.
I am presently developing an application using the James Mail Server,
however after initially setting it up to recieve mail on a local machine
using pop3, I am not able to find any documentation on it's support for
creating other folders like a 'sent' or even 'trash folder'.
[II]
If it is possible to create other folders in James i.e. a 'trash' folder,
how would one delete mail so as to:
(a)Relocate the message from an inbox folder to another folder i.e.
'trash' folder and
(b) completely delete it from the server?

Can java mail be used for distributed exchange server?

H,
I am trying to connect to MS Exchange Server to read my mails using Java Mail API.
I have a questions about using it with Exchange server.
We have 6-7 exchange servers in our company and different users have mailboxes on different servers. My internet mail application will be used by everybody in the company.
But while connecting to exchange server using java mail I can only cnnnect to one server and port. What happens when user mailbox is not on that server. How can I use javamail in this scenario where user mailboxes are on separate servers??
Thanks

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
Regards
RP

Is there any technique to ask Java to connect to mail server?

The Problem is: I would like to use Java Technique to create some mail account on one mail server!

You can use the JavaMail api to send and receive email but not for creating accounts... AFAIK creating a mail account is not standardized in any RFC and depends very much on your mail server.

Java Mail to Yahoo server

How will I send mail to Yahoo mail id using java Mail api. I have used smtp.mail.yahoo.com as smtp server. Remember that I should not use my password.
If possible reply to mail id.
[email protected]
Thanks in advance.

Try this code:
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class AttachExample {
public static void main (String args[]) throws Exception {
String host = args[0];
String from = args[1];
String to = args[2];
String filename = args[3];
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
// Get session
Session session = Session.getInstance(props, null);
// Define message
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));
message.setSubject("Hello JavaMail Attachment");
// Create the message part
BodyPart messageBodyPart = new MimeBodyPart();
// Fill the message
messageBodyPart.setText("Here's the file");
// Create a Multipart
Multipart multipart = new MimeMultipart();
// Add part one
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
// Create second body part
messageBodyPart = new MimeBodyPart();
// Get the attachment
DataSource source = new FileDataSource(filename);
// Set the data handler to the attachment
messageBodyPart.setDataHandler(new DataHandler(source));
// Set the filename
messageBodyPart.setFileName(filename);
// Add part two
multipart.addBodyPart(messageBodyPart);
// Put parts in message
message.setContent(multipart);
// Send the message
Transport transport = session.getTransport("smtp");
transport.send(message);
When running the program type this line:
java AttachExample smtp.mail.yahoo.com email_address_from email_address_to filename
Be sure to turn your yahoo account to pop messages other than the browser.Just go to Options & click on the pop accounts & set it.
Take care

The debug output doesn't show an obvious problem. You're
going to have to actually debug your program. A debugger

Java mail with proxy server

Hi I am a novice, working on a mail sender though proxy. I read Java mail FAQ in http://java.sun.com/products/javamail/FAQ.html#proxy.
And also I found a snippet in below therad.

I installed CCProxy in my machine and gave my own IP address ( 1. LAN IP and 2. IP from whatismyip.com; both works ) and port number. It works. But I gave IP addrss of my friend ( 1. LAN IP and 2. IP from whatismyip.com; both NONE work ) who got CCProxy and in his machine. But doesnt work ( throws Below exception).

I believe we can give some other socks proxy ip address too, other than CCproxy machine ip address If I am correct. Is there any specific way to use the socks server ip address ( such as provided in many websites, used for open relay) ? I tried some of them, which I am able to ping. But still I get the same exception like connection request timed out.

Error: The e-mail server could not be reached when the system was trying to

Dear All,
I've configured the Mail Transport in Portal successfully with SMTP as MS Exchange Server and Third-party Mailing servers. But due to some licensing issues a new MS Exchange mail server have been setup replacing the existing ones.
And when i configure the Mail Transport in the system i get the below message on the eMail Window:
"Error: The e-mail server could not be reached when the system was trying to send the message!
javax.mail.MessaginException: 530 5.7.1 Client ws not authenticated
I've configured (all the steps) the same way as i used to before and restarted the server as well! Please let me know the issue to be resolved, the telnet to the mailserver is also successful. I've try'd searching SDN, didn't find the exact solution... any notes on this?
Thanks,
MS

Hi,
It will depend on your infrastructure, I am not sure and have limited knowledge on netowrks, but in my current landscape both the system were in same domain, but still i had to maintain proxy configuration.
Since it giving authentication error, it feel it could be proxy error.
Please refer below links which talks about same error :
http://java.sun.com/products/javamail/FAQ.html#smtpauth
Or else i think it is issue with port.
