Do you have journaling turned on?
If you have journaling keeping records of every message then it could grow very fast but that kind of growth is pretty crazy.

Check whether journaling is on.
Is your backup running regularly flushing the logs?
Any emails with large attachments flying around?

Hello
What exactly is taking more and more space.. have a look into your storage groupe files...
Are these the transaction  logs ( F1MB file strating like E0xxxxxxx.log) ?
If it's that, check your backups in order to have a full backup very day.. the only way to flush the transaction logs are full backups of the information store.

I am running backup, but since the number of log files and the data base continue to grow so fast my backup drive can't handle it and will not backup. I am over the available storage. There are thousadns of transaction logs as well about 250G of them after one day and the database its self went from 50G to almost 300G in one day.

so you have a backup problem.
You can consider passing your storage group to "circular logging", just to flush the transaction logs, and then pass again to normal logging.

YOur databases will be dismounted during these operations.

I would urge you to perform a full backup of exchange even to an external hard disk to flush the thousands of logs you have. You will be in a very difficult position if something goes wrong to the server without having a valid backup and that too with this big a store.

This sounds like an email loop.
Something is looping round. The log growth matches the growth in the database.
Check your queues to see if a message is stuck and looping. You could also stop the transport service to see if you can break the loop.

Does the SBS 2008 server backup exchange or do I need a third party application to backup and flush the log files? In order to cleanup the old database since I do not have a good backup will I need to move all the mailboxes and then delete the bad databass? While I am asking all kids of questions let me bring you up to date on what is going on. I found that our server was in an open loop so some *&^ Hole was relaying email through us (this people need to be publicly exicuted). Anyway this is what stated the issue. I have since locked the relay down and cleaned up the log files and database. This was Friday I cleaned up 600G of junk and then all was perfect until about 9pm last night when it started again. This time the relay is closed so something else is causing the issue now.

It is very hard to turn SBS 2008 in to an open relay. Which error was made to do that? Alas if your server is an open relay it will be found and abused.

The SBS backup will flush the logs. However as it is SBS 2008, creating a new Storage Group and then mailbox database isn't much of a problem. After you have moved everything, drop the original database and immediately restart the information store service to get the system mailboxes to recreate.

If you are in doubt, check whether you are an open relay here

We were in open relay, I closed it and then found that one of our exchange accounts had become "infected" I had to delete that account and recreate it to fix the problem. (I exported the users data to .pst first)

Does this mean you were still an open relay? If so, would you mind sharing what you did to repair this?
