In the console tree, right-click a virtual server, and then
click Properties.
On the Message Format tab, select one of the following
options:
Provide message body as plain text. A MIME message body
is composed of text only. Graphics and active links are replaced
with textual representations. Character formatting, such as bold,
underline, and color is not retained.
Provide message body as HTML. A MIME message body is
generated in HTML. This format allows messages to display graphics,
support links to other documents, and retain character
formatting.
Both. Plain text and HTML versions are generated in a
MIME multi-part alternative message. If a client cannot read one
format, the other is available.
