The problem is the “[unknown]” value given to EHLO. Usually this would be your IP, but for some reason this fails on your machine. Probably my code for finding the local IP which is not correct or good enough. I'll look into it.

I have attempted to improve the code for detecting the local IP. Tomorrow I'll compile a beta for you to try out.
Thanks for reporting this issue.

Let me know if I can help. If you compile your lookup code alone and make it print something out to stdout, I can run it on my machine.
