      Hi list!
      My postfix used to run together with spamassassin mensioned in
      master.cf as -o content_filter=spamassassin.
      I have removed spamassassin because spamc and postfix process cleanup
      were knocking my server down (swap space at its 80% full).
      I suspect it is because an aliases miss configuration.
      Looking at logs , not alway but just sometimes i get this:

      Apr 9 22:16:54 mail postfix/error[18713]: 72882266C7: to=<double-

        Look for obvious signs of trouble
        =================================

        Postfix logs all failed and successful deliveries to a logfile. The file is
        usually called /var/log/maillog or /var/log/mail; the exact pathname is defined
        in the /etc/syslog.conf file.

        When Postfix does not receive or deliver mail, the first order of business is
        to look for errors that prevent Postfix from working properly:

        % egrep '(warning|error|fatal|panic):' /some/log/file | more
        ============================================================

        Note: the most important message is near the BEGINNING of the output. Error
        messages that come later are less useful.

        The nature of each problem is indicated as follows:

        * "panic" indicates a problem in the software itself that only a programmer
        can fix. Postfix cannot proceed until this is fixed.

        * "fatal" is the result of missing files, incorrect permissions, incorrect
        configuration file settings that you can fix. Postfix cannot proceed until
        this is fixed.

        * "error" reports an error condition. For safety reasons, a Postfix process
        will terminate when more than 13 of these happen.

        * "warning" indicates a non-fatal error. These are problems that you may not
        be able to fix (such as a broken DNS server elsewhere on the network) but
        may also indicate local configuration errors that could become a problem
        later.

          I have a few accounts who forward a copy of all their mail to gmail addresses. For example, this account mirrors to a gmail account so I have access to my mailing list archives even when I am working on my server.

          While testing postfix 2.10 I am getting:

          This is happening on all the accounts that forward to gmail.

          I am also now getting this error on mail to the postfix list, so it is possible that when this clears up a duplicate of this post will end up on the list. I apologize in advance, I'll try and remove it from the queue.

                debug logging is rarely useful with postfix. 99%+ of the time
                normal logging is sufficient to solve whatever problem you're
                having. As in this case.

                  adding

                  smtp unix - - - - - smtp

                  didn't solve the problem, though it led to many different errors.

                    Well, yes, *that* was stupid.

                    smtp unix - - n - - smtp

                    *cough*
