I recently installed and configured postfix on a new server that will be replacing our old mail server. The old server is running version 2.2.10 and the new one has 2.3.3.
It's working well, and I tried to duplicate the configuration as much as possible, but there is one quirk I have not been able to sort out. On the old server, when I go to /var/mail and open one of the inboxes, each message has X-UID, Status, and X-Keywords headers. On the new server, none of the messages have those headers. On the new server, each inbox has the following message at the top, which does not appear on the old server: >From MAILER_DAEMON Wed Jun 03 20:40:08 2009 Date: Wed, 03 Jun 2009 20:40:08 -0500 From: Mail System Internal Data <mailer-dae...@xxxxxxx.com> Subject: DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA Message-ID: <1244079...@xxxxxxx.com> X-IMAP: 1244077580 0000002441 $Junk $NotJunk Status: RO I would like all the messages on the new server to have at least the X-UID header. What did I miss? Thanks, Adam
