Hi there, Sorry for the trivial question, I am a little confused what is a bounce message and how not to get these internal Postfix messages.
From my server hub-dev-app01.dev.medplus.com, I send a message to hub-int-app01.dev.medplus.com. (They both running Postfix 2.3.x). Because my recipient address has a typo (correct domain but wrong address), hub-dev-app01.dev is sending the message sender the following message. This is correct behavior. Is the following an example of bounce message? Our user is not interested getting such messages, so I configured /etc/postfix/main.cf to assign empty value to "notify_class". notify_classes = But why am I still getting these messages? Thanks, Yan Received: by dir-dev-app01.dev.medplus.com (Postfix) id 7CACCC806D; Wed, 15 Jun 2011 18:02:59 +0000 (UTC) Date: Wed, 15 Jun 2011 18:02:59 +0000 (UTC) From: mailer-dae...@dir-dev-app01.dev.medplus.com (Mail Delivery System) Subject: Undelivered Mail Returned to Sender To: yz...@direct.dir-dev-app01.dev.medplus.com Auto-Submitted: auto-replied MIME-Version: 1.0 Content-Type: multipart/report; report-type=delivery-status; boundary="30DADC8069.1308160979/dir-dev-app01.dev.medplus.com" Message-Id: <20110615180259.7caccc8...@dir-dev-app01.dev.medplus.com> This is a MIME-encapsulated message. --30DADC8069.1308160979/dir-dev-app01.dev.medplus.com Content-Description: Notification Content-Type: text/plain; charset=us-ascii This is the mail system at host dir-dev-app01.dev.medplus.com.
