That is because you did not set the Host property before calling Connect().
In fact, DO NOT call Connect() at all!  Only call Send(), which will then
call Connect() internally as needed for each recipient.  That is the whole
point of SMTPRelay - to take a message as input and figure out where it
needs to be sent on a per-recipient basis.

That is because you are using the SMTPRelay wrong to begin with.  The
DNSServer is used to determine each recipient domain's MX servers, to which
the message is then sent.  But you are not even getting that far yet.
