Hi webchella,

I am also using IMail server. In the admin of Imail, I am choosing a virtual host. There I could see 3 options. 1)Imail Database 2)NT Database3)External Database.

I am choosing the third option and then I clicked on the 'configure' button. Then in the next dialog box, I entered the following details

1) External Database Implementation DLL :- C:\Imail\ODBCUSER.DLL

2) ODBC System Data Source Name :- IMAILSECDB( This DSN is configured in ODBC)

3) Table Name :- emailusers (columns are the same as instructed by IMAIL)

and clicked on OK.

But when I insert a new record, nothing happens. Meaning, I can not see any user added in that particular Virtual Host. Neither it can be authenticated by the IMAIL web interface.

When I am creating users manually(using IMail Database ), It works with Imail web interface as well as the web-mail application made by me.

Please help me out

Regards

Hi,

I am learning to send a mail using SmtpClient. I am getting following expception when I try and send the mail through. Could it be because of some security settings on the SMTP server?

java.net.UnknownHostException: mailhost

at java.net.InetAddress.getAllByName0(InetAddress.java:571)

at java.net.InetAddress.getAllByName0(InetAddress.java:540)

at java.net.InetAddress.getByName(InetAddress.java:449)

I have the name of the SMTP server and also have the IP address. I can ping the SMTP server using the name. I still do not understand what is the problem. I have set the internet option to exclude internal servers from going through the firewall. So it should behave as if there was no firewall. DO you think there may be other security setup on the SMTP server?

Thanks in advance

Hi

i'm trying to create an E-mail client with spam filters using Javamail.Till now i can sent and receive email with attachments.I have an addressbook and a text editor.At the moment i'm trying to create the main screen with folders (mailbox,sent messages,deleted messages,etc..),a message viewer and a folder viewer(see the email inside the folder when you click on a folder).I used JSplitPanel to display these screens but i have many problems to make them work correctly.For example when i receive an email with POP or IMAP to store it directly to the inbox folder and when i send a mail to store it to the sent messages folder.Above all that i have more problems with the spam filters, how will i make them check everyemail that i receive? I tried everything but i can't find a solution.

Thanks and sorry about the long message.

Hi . I am also having the same problem. My yahoo accout cosmosoftweb503@yahoo.co.in is supportng POP3 and SMTP access.This i have enabled from settings option of the Yahoo mail web page.The strange thing is few days it worked. After that it says mail send but the mail is not actualy send. I have configured my outlook express also for the yahoo accout. Here also i am able to receive .But sending it says send but the message is not received by the receipents.

import java.util.Properties;

import javax.mail.Address;

import javax.mail.Message;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

public class SendEmail

{

public static void main(String[] args) throws Exception

{

if(args.length != 6)

{

System.out.println("Usage: SendMail host user password fromAddress toAddress subject");

return;

}

String host = args[0];

String user = args[1];

String password = args[2];

String fromAddress = args[3];

String toAddress = args[4];

String subject = args[5];

System.out.println("Sending Message");

System.out.println("Host: " + host);

System.out.println("User: " + user);

System.out.println("Password: " + password);

System.out.println("fromAddress: " + fromAddress);

System.out.println("toAddress: " + toAddress);

System.out.println("subject: " + subject);

Properties props = System.getProperties();

props.put("mail.smtp.host", host);

p.put("mail.smtp.port", "587"));

props.put("mail.smtp.auth", "true");

Session session = Session.getDefaultInstance(props, null);

MimeMessage message = new MimeMessage(session);

message.setFrom(new InternetAddress(fromAddress));

message.addRecipient(Message.RecipientType.TO, new InternetAddress(toAddress));

message.setSubject(subject);

message.setText("Test Message");

Transport transport = session.getTransport("smtp");

transport.connect(host, user, password);

message.saveChanges();

transport.sendMessage(message, message.getAllRecipients());

transport.close();

System.out.println("Sent !!!!");

}

}

This is the code i am using. Only change is i have put the smtp.port since the yahoo smtp is on 587. I was wondering how one day it worked for me
