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.
