(Objective-C) 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".
#import <CkoMailMan.h> #import <CkoEmail.h> // 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. CkoMailMan *mailman = [[CkoMailMan alloc] init]; // Set the SMTP server. Perhaps it is the local machine. mailman.SmtpHost = @"localhost"; // Or perhaps it's a particular computer on the local network: mailman.SmtpHost = @"192.168.1.123"; // Or provide a local domain that resolves to an IP address on the local network: mailman.SmtpHost = @"mymailsesrver.com"; // Set the SmtpAuthMethod property = "NONE" mailman.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 CkoEmail *email = [[CkoEmail alloc] init]; email.Subject = @"This is a test"; email.Body = @"This is a test"; email.From = @"Chilkat Support <support@chilkatsoft.com>"; BOOL success = [email AddTo: @"Chilkat Admin" emailAddress: @"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 != YES) { NSLog(@"%@",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 != YES) { NSLog(@"%@",@"Connection to SMTP server not closed cleanly."); } NSLog(@"%@",@"Mail Sent!"); |
