Newbie Alert ;-) Summary: Installation on Windows 7 64-bit, Java7, Postgres 9.3, of latest James puts message in queue, but does not send (or receive). There is seems to some problem with Java IO.
Gory details are being blogged at: http://apachejames.wordpress.com/ Does not solve even after allowing full control of java.io.tmpdir on the system using icacls. Thanks, I hope to build this into an useful blog to assist Windows users.
