If you want more convincing, please go and read RFC 2821. I can assure
there is NO WAY Exim can "ask for a relay". There just isn't such a
facility in the protocol. When I look at your two original dialogues, I
see this:

They appear to be different hosts - that might make a difference.
Especially as the first one says "SMTP relay" whereas the second one
says "SMTP MX". That strongly suggests that the first one is set up for
relaying and the second one is not.

The contents of the EHLOs are different. That *shouldn't* make a
difference, but...
The remaining commands sent by Exim and Sendmail are identical.
It seems most likely that it is the different hosts that make the
difference. The question is *why* are different hosts being used?
Presumably it's something in the way Exim and Sendmail are set up. As I
don't know Sendmail, I can't help, but as another poster has said, you
need to set up a router to make Exim send to smarthost (as per example
in the manual and the book).

No there is not.

Aha! That one is saying "SMTP Relay", you notice, NOT "SMTP MX".
You never actually posted the router and transport you are using. If you
had done that, people on this list could probably say why it was using
different hosts in the different cases.
