Basic Headers Basic Headers Set the following properties (only in %Net.MailMessageOpens in a new tab) to specify the most commonly used headers of the message itself: To — (Required) The list of email addresses to which this message will be sent. This property is a standard InterSystems IRIS list; to work with it, you use the standard list methods: Insert(), GetAt(), RemoveAt(), Count(), and Clear(). From — (Required) The email address this message is sent from. Date — The date of this message. Subject — A string containing the subject for this message. Sender — The actual sender of the message. Cc — The list of carbon copy addresses to which this message will be sent. Bcc — The list of blind carbon copy addresses to which this message will be sent. Note: You should be aware of the requirements of the SMTP server that you are using. For example, some SMTP servers require that you include a Subject: header. Similarly, some SMTP servers do not permit arbitrary From: headers.
