Cutting to the chase, from poster, the (relevant, edited) headers are: > Received: from a2s47 by m1pismtp01-023 > Received: from smtp1 by a2s47 >From list: > Received: from vms169129pub by p3pismtp01-026 > Received: from a2s47 by vms169129 for [email protected] (ORCPT tj.sherlock) > Received: from localhost by a2s47 > Received: from smtp1 by a2s47 First, note the "from localhost" entry in the second series. This means that Mailman is reinjecting the message on the same host. It doesn't appear in the first series; Mailman did *not* handle that message, it was relayed *directly to you* by the MTA at a2s47. Second, apparently the list knows you as "tj.sherlock at verizon", but it's likely the direct mail was originally addressed to "tom at ramruva". I would guess that the sender is BCC'ing you (perhaps to help you identify any problems?) It's hard to say because I don't know Microsoft Exchange, but it is quite possible that the mail from the sender's host is going to multiple recipients (ie, other than the list) at the point where her MUA injects it. If there were a single message to the list only, the first MTA in the chain will often have a "for mailing-list" clause in the Received header. Its absence doesn't prove anything, but certainly leaves open the possibility of multiple recipients. A lower probability is that there's a rule or alias at a2s47's MTA that BCCs you on list mail, again for debugging purposes. (Coincidentally, yesterday I implemented exactly that feature using the same MTA (Exim 4) for a list I run, although the purpose was different. It's just one line in /etc/aliases.) As unlikely as that seems, based on the Received chain posted, I would say a problem with Mailman is even less likely. I just don't see how Mailman could be involved with the direct mail. I'm sorry we can't find a Mailman issue here, in the sense that we could help you with that. ------------------------------------------------------ Mailman-Users mailing list [email protected] http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
