I just ran a test session http://debug-me.joeyh.name:8081/75e73467-e2bb-4d0e-809b-5b1991228710.
It seemed to work ok, except that no logs were mailed afterwards. I checked the logs on the MX, and didn't see any connects.
Seperately, but possibly related I reported a debian bug about trying to get emailing logs working on my own server.
This is caused by debug-me.service containing
I've fixed the server and will release a new debug-me version fixing it.
