Hello,

Either quit using postmaster@ for sending emails or modify exim.conf:

  drop  message = MULTIPLE_BOUNCE_RECIPIENTS
        senders = : postmaster@*
        condition = ${if >{$recipients_count}{0}{true}{false}}

The string MULTIPLE_BOUNCE_RECIPIENTS is defined in /etc/exim.strings.conf

MULTIPLE_BOUNCE_RECIPIENTS=Legitimate bounces are never sent to more than one recipient.
