If you're using ACE/IIB a publication with no subscribers will go through the NoMatch terminal. That may be because it's the "wrong" name or because there are no subscribers online at the time of publication.
But don't forget there's no way within MQ Pub/Sub to distinguish between a misspelt topic name and a topic name that an application (and ACE/IIB is just another application in this context) has invented dynamically.

MQ will create a topic if it is not already present. It does not care if no one ever subscribes to it. However, it could lead to issues in MQ if there are large numbers of messages queued for durable subs or retained msgs.

You have 2 terrible options in my view:
- you can create a durable subscription that subscribes (using a top level wildcard) to every single publication, and an application that reviews them looking for "wrong" ones
- you can create a channel exit that logs all of the messages that pass through it. The dangers and problems of using exits are well documented on this forum.

Why? Seriously? What's the use case? What will you use these logs for?
If (as you say) you're looking for topics that are not defined on the queue manager (and that brings up a whole question about using dynamic or static subscriptions) why not use topic security to prevent publications to "illegal" topic names?

The same general approach to restricting naming of permanent or temporary dynamic reply-to-queues.

You can use MQ Auditor to audit/track all queues and/topics of a queue manager.

If there is an app requirement to log particular transactions / messages, it should be done in the app, in a format and logging destination that suits the app.
