(Android™) Send Email without Authentication (no Login)Demonstrates how to send email using an SMTP server that does not require authentication. An SMTP server that needs no authentication should be protected by a firewall, to prevent outsiders from using it as a SPAM server. To send email without logging in, simply set the mailman's SmtpAuthMethod property = "NONE".
// Important: Don't forget to include the call to System.loadLibrary // as shown at the bottom of this code sample. package com.test; import android.app.Activity; import com.chilkatsoft.*; import android.widget.TextView; import android.os.Bundle; public class SimpleActivity extends Activity { private static final String TAG = "Chilkat"; // Called when the activity is first created. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // The mailman object is used for sending and receiving email. CkMailMan mailman = new CkMailMan(); // Set the SMTP server. Perhaps it is the local machine. mailman.put_SmtpHost("localhost"); // Or perhaps it's a particular computer on the local network: mailman.put_SmtpHost("192.168.1.123"); // Or provide a local domain that resolves to an IP address on the local network: mailman.put_SmtpHost("mymailsesrver.com"); // Set the SmtpAuthMethod property = "NONE" mailman.put_SmtpAuthMethod("NONE"); // Set the SMTP login/password (this may be omitted given no authentication will take place) // mailman.SmtpUsername = "myUsername"; // mailman.SmtpPassword = "myPassword"; // Create a new email object CkEmail email = new CkEmail(); email.put_Subject("This is a test"); email.put_Body("This is a test"); email.put_From("Chilkat Support <support@chilkatsoft.com>"); boolean success = email.AddTo("Chilkat Admin","admin@chilkatsoft.com"); // To add more recipients, call AddTo, AddCC, or AddBcc once per recipient. // Call SendEmail to connect to the SMTP server and send. // The connection (i.e. session) to the SMTP server remains // open so that subsequent SendEmail calls may use the // same connection. success = mailman.SendEmail(email); if (success != true) { Log.i(TAG, mailman.lastErrorText()); return; } // Some SMTP servers do not actually send the email until // the connection is closed. In these cases, it is necessary to // call CloseSmtpConnection for the mail to be sent. // Most SMTP servers send the email immediately, and it is // not required to close the connection. We'll close it here // for the example: success = mailman.CloseSmtpConnection(); if (success != true) { Log.i(TAG, "Connection to SMTP server not closed cleanly."); } Log.i(TAG, "Mail Sent!"); } static { System.loadLibrary("chilkat"); // Note: If the incorrect library name is passed to System.loadLibrary, // then you will see the following error message at application startup: //"The application <your-application-name> has stopped unexpectedly. Please try again." } } |
