DSN Support for Exim. This patch allows Exim 4.xx to support the sending of email Delivery Status Notifications.
From Exim 4.83 onwards DSN is now included as standard (based on this patch).

The qmail-maxrcpth.patch patch allows you to set a limit on how many recipients are specified for any one email message. RFC 2821 section 4.5.3.1 says that an MTA MUST allow at least 100 recipients for each message, but MAY elect not to allow any more than that. I choose not to, since this is one of the favourite tricks of the spammer.
To set the limit, create a /var/qmail/control/maxrcpt file which contains the maximum number of recipients you wish to allow.
