If you use JavaMail api provided by Sun then you can get the latest api from Sun Downloads.\nJavaMail uses properties to load all configuration to the program.\nYou must specify:\n# The hostname or IP address of your SMTP server\n    mail.smtp.host=smtp.duke.java.sun.com\n\n    # You get lots of debugging information if\n    # this is turned on. Comment this line to turn\n    # it off.\n    mail.debug=true\n\n    # The To email address\n    ttapr2004.to=duke@duke.java.sun.com\n\n    # The From email address\n    ttapr2004.from=duke@j2ee_fanclub.java.sun.com\n\nYou can easily connect without authenticate to the SMTP server. But you may experience that you cannot send email from your java program:\n1. Your ip may be blocked by firewall to access SMTP server\n2. Your SMTP server block senders address, to address and maybe your ip.\n3. Your SMTP server requires authentication\n\nIf your server requires authentication this  igot it from internet\n--------------------------------------------\npublic class SendMailUsingAuthentication {\n\n  private static final String SMTP_HOST_NAME = "myserver.smtphost.com";\n  private static final String SMTP_AUTH_USER = "myusername";\n  private static final String SMTP_AUTH_PWD = "mypwd";\n\n  private static final String emailMsgTxt =\n      "Online Order Confirmation Message. Also include the Tracking Number.";\n  private static final String emailSubjectTxt = "Order Confirmation Subject";\n  private static final String emailFromAddress = "sudhir@javacommerce.com";\n\n  // Add List of Email address to who email needs to be sent to\n  private static final String[] emailList = {\n      "mark@yahoo.com", "robin@javacommerce.com"};\n\n  public static void main(String args[]) throws Exception {\n    SendMailUsingAuthentication smtpMailSender = new\n        SendMailUsingAuthentication();\n    smtpMailSender.postMail(emailList, emailSubjectTxt, emailMsgTxt,\n                            emailFromAddress);\n    System.out.println("Sucessfully Sent mail to All Users");\n  }\n\n  public void postMail(String recipients[], String subject,\n                       String message, String from) throws MessagingException {\n    boolean debug = false;\n\n    //Set the host smtp address\n    Properties props = new Properties();\n    props.put("mail.smtp.host", SMTP_HOST_NAME);\n    props.put("mail.smtp.auth", "true");\n\n    Authenticator auth = new SMTPAuthenticator();\n    Session session = Session.getDefaultInstance(props, auth);\n\n    session.setDebug(debug);\n\n    // create a message\n    Message msg = new MimeMessage(session);\n\n    // set the from and to address\n    InternetAddress addressFrom = new InternetAddress(from);\n    msg.setFrom(addressFrom);\n\n    InternetAddress[] addressTo = new InternetAddress[recipients.length];\n    for (int i = 0; i < recipients.length; i++) {\n      addressTo[i] = new InternetAddress(recipients[i]);\n    }\n    msg.setRecipients(Message.RecipientType.TO, addressTo);\n\n    // Setting the Subject and Content Type\n    msg.setSubject(subject);\n    msg.setContent(message, "text/plain");\n    Transport.send(msg);\n  }\n\n  /**\n   * SimpleAuthenticator is used to do simple authentication\n   * when the SMTP server requires it.\n   */\n  private class SMTPAuthenticator\n      extends javax.mail.Authenticator {\n\n    public PasswordAuthentication getPasswordAuthentication() {\n      String username = SMTP_AUTH_USER;\n      String password = SMTP_AUTH_PWD;\n      return new PasswordAuthentication(username, password);\n    }\n  }\n}\n--------------------------------------------

You can't. Some clients have an option, but not all clients send back the 'email read' response.

You have to use a mail client such as outlook. You should also know the outgoing and incoming server addresses. Then you're set.

Your best best is to cpntact your Internet service provider.\n\nYou may have set your SMTP information incorrectly.\nsmtp is usually one of two\n\nsmtp.domain.com or\nmail.domain.com\n\nwhere domain.com is the domain of your mail server. Your ISP will know best. If you set it to smtp and it supposed to be mail or vice versa then outgoing might work some times and not at other times.\n\nSome SMTP servers require authentication.\n\nTo change account settings click on TOOLS and select EMAIL ACCOUNTS. Make sure View or EDIT existing accounts is selected and click NEXT. Click on the email account that is giving you problems and click CHANGE (or just double click the account).\n\nTo set smtp authentication, click the MORE SETTINGS button in the ACCOUNT Window infront of you and then click the OUTGOING SERVER tab. MArk the checkbox MY OUTGOING SERVER REQUIRES AUTHENTICATION. Use the same settings as incoming mail server ussually is the right option.\n\nIF this is already enable then disable it. Play around you will getting.\n\nOH yes ou didn't mention what error number Outlook indicates in  SEND/RECEIVE STATUS.\n\nSome Antivirus programs can also interfere with outgoing mail, if they have expired , have become corrupted, or are disabled.\n\nI hope this helps.

If you run Windows as your OS, you might want to try MailEnable as the SMTP server and Telemagic as your mailer program.   You might also want to simply use PHP + Pear, and a database like MySQL to store the email content, etc.  A lot of options, many free, other than the time invested.

you can't\nanyone can make an account and send mail out as anyone else. I suggest you do not have a catchall or default e-mail address and that if mail is sent to an address not specifically configured under your domain, you bounce it.\n\nResponsible spam filtering software will not give you trouble, as they block mail coming from a specific IP, specific messages or following spam patterns. \n\nIf you can identify from which smtp (outgoing mail) server the mail is being sent by looking at the headers of a message, you can find out which ISP is responsible for that IP and semnd a complaint to their abuse department.

NO!\n\nyou cant!\n\n\nYou cantrace via IP in the headers.. Thats it..\n\nE-mail is such a old and crappy system!  Someone is spamming you with you as teh sender, its easy to do and hard to stop!\n\nget yourself some AV software with anti spam , or use mozilla thunderbird.

i think there is no such way by which you can check that someone is accessing your mail from other computer and he/she can again mark it as unread.\n\nPLz tell me if you can get any method.

Yes, the problem you are having is either the smtp or the pop3 setting you entered is wrong , two likely the server is down that you are connecting to and you may try again, then thirdly you have to be sure you are using your correct username or password

Have you entered your username and pw for SMTP authentication?  You have to authenticate for both incoming and outgoing messages when using an email client w/yahoo mail plus.
