The body format must have the value ‘text’ or ‘html’.

In the /NotificationClasses/NotificationClass/Protocols section of the ADF, each notification class is configured to use one or more delivery protocols. Each delivery protocol uses its own set of fields when delivering a notification. If you use the SMTP delivery protocol, you can optionally specify the BodyFormat field, which tells the SMTP delivery protocol whether the e-mail message body is plain text or HTML. If you do not explicitly specify a value for BodyFormat, the value ‘text’ is used by default. If you do specify a value, it must be either ‘text’ or ‘html’. It looks similar to the following if you want a fixed value across all e-mail messages:

<field><fieldname>BodyFormat</fieldname><sqlexpression>’Html'</sqlexpression></field>

Or, if you want to vary the BodyFormat value from one message to the next, you can do something similar to this:

<field><fieldname>BodyFormat</fieldname><sqlexpression>NotificationBodyFormat</sqlexpression></field>

In this case you need to have a field in your <notificationclass> element called NotificationBodyFormat, and this field must have a valid format for each notification.</notificationclass>
