I have encountered exactly the same thing.
Everytime exim is called it is doing this. You can run

'exim -bp' (give current queue).

Even with an empty queue it is the same thing. I was able to stop this
by setting option 'primary_hostname=MyMachine' in the exim.conf file,
but now all remote messages are no longer delivered. See my mails
earlier on this list.

I have been trying to find out what all this is about, but has not come
very fare except from getting some log files.

What system are you running? I am using Debian woody with exim 3.32

This could as well be an issue of libc6 resolver. Can an exim developer
comment on this perhaps?
