Block mailer daemon emails for manually blocked email IDs using access map

  • 772

I have blocked emails to some addresses by using line like 

To:[email protected]                  ERROR:"550 Mailbox disabled for this recipient"

But I am getting lot of messages from "Mail Delivery Subsystem ". How do I disable getting MAILER-DAEMON notifications only for this user? I can do this in my email client but I was hoping for more efficient method to stop server from sending such emails.

I do not want the other mails from "Mail Delivery Subsystem " to be stopped. The error message should not be sent for the addresses which I have manually blocked in access map.

  1. At first glance, warren's answer seems to suggest that you dump all messages, but of course you could set up procmail to only dump the ones from MAILER-DAEMON which actually refer to [email protected]. This is done with something like

    # Postmaster notifications: Move to doublebounces if refering to [email protected]
:0 H
* ^From: .*[email protected]
* ^Subject: (Postmaster notify|Returned mail): .*
{ :0 B
  * [email protected]
  doublebounces
}

    Your questions does not clearly state which type of bounces you get. I assume it is so-called double bounces. You might want to have a look at a more sophisticaed solution which I posted at Sysadmin'ish Blog: Selective Sendmail Postmaster

    Note: Above procmail recipes are meant for large servers and try to minimize the load. The 2 recipes could be converted to 1, however slightly more expensive.

  2. You could setup a procmail recipe to just dump the messages to /dev/null from that address/domain.
