The format of the queue-id in its Received headers: ... id <0nla00500vsmv...@a-mtaout20.012.net.il> ... is unlike that of Postfix, Exim or Sendmail from sendmail.org. The only similar form I'm finding is: (Oracle Communications Messaging Server 7u4-23.01 (7.0.4.23.0) 64bit (built Aug 10 2011)) with ESMTP id <0lxi003bg7hg1...@mail-out.apple.com> If we look at the ids side by side: id <0lxi003bg7hg1...@mail-out.apple.com> id <0nla00500vsmv...@a-mtaout20.012.net.il> My best guess is that these are related. -- Viktor.
