I'm using Exim on my mail server, and trying send email to [email protected] address. I got email from this address, and make "replay" then.
But - I have return from my SMTP with Mail delivery failed: returning message to sender:
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

someuser - of course here is correct value.
dig returns all data for hotmail.com:
$ dig hotmail.com +short
157.56.172.28
65.55.77.28
157.55.152.112
65.55.85.12
$ dig hotmail.com +trace

;; global options: +cmd
;; Received 17 bytes from 77.***.***.133#53(77.***.***.133) in 1 ms
77...133 - my datacenter's DNS.
So - all seems correct, but...
P.S. Sent email from Google mail - and it was deliver normally.
UPD
$ telnet mx1.hotmail.com 25

Look like you send your message via smarthost (mail.domain.org.ua) that is not properly configured and can't determine the way to the hotmail.com. Try to modify your outgoing router to send messages directly to the corresponding MX instead of smarthost.
