//  Note: the distributionList.txt file contains one email
//  address per line.  For example:
// 
//  matt@chilkatsoft.com
//  "Chilkat Admin" <admin@chilkatsoft.com>
//  <support@chilkatsoft.com>
// 
//  An email address may contain both the friendly name (in quote)
//  and the email address (in angled brackets).  The friendly
//  name is optional.  When the friendly name is missing,
//  angled brackets are optional.

//  If the SendIndividual property is true, then the email
//  is sent individually to each recipient in the list using
//  the "To" header field.

//  If the SendIndividual property is false, then emails
//  are sent in batches of 100 BCC's.  Your program should
//  provide a single "To" address, such as:
email.AddTo("My List","listAdmin@chilkatsoft.com");

//  This example will send emails individually, so we'll clear
//  the "To" list.
email.ClearTo();

//  Set the mailman's SendIndividual property = true
mailman.SendIndividual = true;
