Although I can't check your HELO unless you send an SMTP msg, I agree
that you have your PTR and A in order. And your SPF record permits
sending from those two boxes as well. You're not on any public BLs.

When you say the logs "show everything ok", though, I have to wonder
what you mean; obvs. there must be an aberrant QUIT in sessions to
Hotmail. Have you done a real packet trace (note IIS SMTP logs will
show network errors)?
