You're getting Bad signature because gpg can't find the key. And it can't find
it because the keyserver helper program is being blocked at your proxy server.

In addition to auto-key-retrieve, try specifying http-proxy[=value] as part of
the keyserver-options line in gpg.conf.

From the gpg man page:

            For HTTP-like keyserver schemes that (such as HKP
            and HTTP itself), try to access the keyserver over
            a proxy. If a value is specified, use this as the
            HTTP proxy. If no value is specified, the value of
            the environment variable "http_proxy", if any, will
            be used.

If that doesn't work, you may either

  a) ask the Net-gods to open the keyserver port, 11371. Or,
  b) try to locate a keyserver operation on port 80.
