Hi all, Today seems to be postfix day, so sorry for the bulk of questions ;-)
When I receive a mail with only ONE envelope recipient, postfix inserts a mail header of the form Received: from localhost (localhost [127.0.0.1]) by mail.mydomain.com (Postfix) with ESMTP id F335A4A4084 for <[EMAIL PROTECTED]>; Fri, 29 Aug 2008 12:23:23 +0200 (CEST) Which is nice, because this way I see the original envelope recipient even when the To: header is forged. During mail delivery with multiple envelope recipients the generated Received: header looks like this: Received: from localhost (localhost [127.0.0.1]) by mail.mydomain.com (Postfix) with ESMTP id 2FAE74A406F; Fri, 29 Aug 2008 12:20:13 +0200 (CEST) Of course there is no "for ..." part because there are multiple recipients. Is there a way to enforce postfix to always insert a "from ..." part on its Received: header? Maybe by specifing default_destination_recipient_limit = 1 ? If yes, has default_destination_recipient_limit=1 any bad side effects? Thanks and regards -stefan-
