Well, I built the specific version of Postfix we use on that server, 2.11.3, and packaged it as an rpm using mock. I did not notice any additional binaries at the time. But then I was not looking for them either. I am not clear on this resolution either. Actually, I do not have a clue about what it is that you are trying to tell me. What is a short HELO and why would my server be issuing one? -- *** E-Mail is NOT a SECURE channel *** James B.
