That's not postfix as such - you probably have a proxy of some sort (or a non transparent hardware NAT / port forwarder) in front The postfix faq should fix that for you. On Fri, Dec 17, 2010 at 7:16 PM, <bill@kruchas.com> wrote:

  Hello,

      I have a misconfigured postfix installation, I inherited. Does   anybody know of anyone who would consider reconfiguring/fixing it.

      It seems that all mail presented to it appears to be from   "localhost", when i reject unautorized destinations, it rejects all   mail.

  Thanks in advance.
