When message is declared as multipart (by having
appropricate Content-Type header), that means it contains
one or more parts that are 'separated' from the
text of the message. For example, some mail clients will
send formatted messages so that they send plaintext as
regular message text, and formatted as separate part.
You will notice that message has parts when text is
something like
This is a multi-part message in MIME
format.
which means that actual message is stored in one of
message parts. So, to locate text you are looking for,
instead of looking at
Message.Text
try
Message.Parts(0).Text
Message.Parts(1).Text
or similar - depending how many parts are in the
message. You can get total number of parts using Count
property.
