//  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 (obviously, use your SMTP server, not chilkatsoft.com)
mailman.SmtpHost = @"smtp.chilkatsoft.com";

//  Set the SMTP login/password (if required)
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>";
success = [email AddTo: @"Chilkat Admin" emailAddress: @"admin@chilkatsoft.com"];
//  To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

//  To send high-priority email, 
//  add the X-Priority header field with the value "1" 
//  to indicate highest-priority.
//  A value of "3" is normal, which is the same as not setting
//  the X-Priority header at all, and "5" is the lowest. 
//  "2" and "4" are in-betweens.

//  Microsoft Outlook might add the following headers when
//  sending high-priority email.

//  X-Priority: 1 (Highest) 
//  X-MSMail-Priority: High 
//  Importance: High 

//  The X-Priority header alone is enough to make the email high-priority.

[email AddHeaderField: @"X-Priority" fieldValue: @"1"];

//  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];

    NSLog(@"%@",mailman.LastErrorText);
