Exchange 2010 Message Journaling and transaction logs.

I have an Exchange 2010 SP3 running on a single Windows 2008 R2 server.  I have recently implemented a third part journaling solution that had me create a journaling mailbox that receives all the messages and then moves them to the Journaling storage area. I would like to prevent these messages that are sent to this mailbox from being logged to my transaction log file.

My thinking is that since it is a separate platform where the messages are stored that I don't need tran logs for it for two reasons.
1- It uses a fair amount of space in the tran logs that I don't think is necessary.
2- In the event of a transaction log restore(hopefully never) I would end up with duplicate messages in my journal.

Disabling transaction logs for this mailbox seem to be the best way to do this. Is this possible?

I was thinking that because the mailbox for journaling was from a third part, that I would have to disable it on an individual basis.

But from your suggestion, I see that if I create a separate database for my journaling mailbox, that then I can control it's logging independent of the other mailboxes in the main mailbox database. Is my thinking correct?
