The IJG mailing list for libjpeg is firstname.lastname@example.org
See http://ijg.org/archives/ for mail list archives.
The list is actually pretty active considering how little development / change is going on with JPEG these days. Tom Lane, Guido Volbeding and a few others usually provide timely responses.
