Just put it in the global part of your config. If you search for
/^|message_logs/ in the spec.txt, you'll find about the following:


+------------+---------+-------------+-------------+
|message_logs|Use: main|Type: boolean|Default: true|
+------------+---------+-------------+-------------+

If this option is turned off, per-message log files are not created in the
msglog spool sub-directory. This reduces the amount of disk I/O required by
Exim, by reducing the number of files involved in handling a message from a

The is "Use: main". It refers to the global part, before any

The mainlog may rotate away. If you've a message, you're loosing
information about the message. And, w/o message_logs you loose the

    exim -Mvl <message-id>


command, which is quite handy if you need fast access to the reasons,
why a message is not delivered yet.

On heavily loaded inbound systems we do not use the message logs,
because these systems forward the messages to outbound or storage
anyway. But on the outbound systems we use the message logs.
