      It sounds like there is some permission problems on postfix working
      directories or that you are running postfix as an other user or similar.

      Check which owner Postfix is running as and what permissions
      /var/lib/postfix/ has (I think), there might be more or other places.

        Hello Patric,

        Thanks for your quick Reply,

        Looks like our ISP got us out of the blacklist, and all of the emails in the
        queue where delivered during the night, but my question is the following,

        Why were we getting the same 451 error inside our network?, I understand
        that if we are marked as a Spam we can´t send them out, but what about the
        inside of the network?

        Thanks a lot,

        Alan

        It sounds like there is some permission problems on postfix working
        directories or that you are running postfix as an other user or similar.

        Check which owner Postfix is running as and what permissions
        /var/lib/postfix/ has (I think), there might be more or other places.

          Out of UCEprotect? The ISP did this for you? Both of these claims
          appear highly unlikely, as was the implied belief that Hotmail/MSN
          uses UCEprotect.

          Let's examine the log that you posted. Note, it is in plain English
          so as to be understandable.

          Host mx2.hotmail.com (at IP address 65.54.188.72) said (presumably to
          your smtp(8) client), "451 Couldn't open temporary file," in reply to
          your DATA command. So, apparently there was some problem at this
          particular Hotmail MX host. The assumption that it was associated
          with a listing on UCEprotect is unfounded and farfetched.

          This was wrong. Nothing posted indicated an issue in the OP's
          installation of Postfix.
