It happens to me fairly often.
What's happening (as far as I can see)
1) the lookup for abc.org failed in such a way that your local
nameserver thinks that there's no such domain.
2) In that case, it searches through it's search list of
domains to see if it's a local address with the domain truncated.
3) You're at a .org site, so .org is in your search list.
4) so one of the addresses it looks up is abc.org.org
5) Which is a valid host, since the owner of org.org
has setup his DNS to return 127.0.0.1 for all lookup attempts
to his domain.
6) so your mail server attempts to deliver the mail to itself,
detects this and error's out permenently.
If 5) wasn't there, then it would bounce with a no such domain error.
Of course, abc.org probably does exist, and it was just a DNS error,
but the local system can't tell that.
You also only see this if your sending system is a .org
