Priv.edb data size increasing even after defragmentation
I am running Exchange 2003 Sp2 Standard Edition and I am having an issue with the EDB file for the mailboxes growing at a very rapid rate.
I recently ran a offline defrag and the database reduced from 80GB down to 30GB. Within 7 days it was back up to 50GB and growing. This is the second time I have done this in 2 months. The logical free space shows about 20-30GB.
I am a bit concerned that the increase in size will impact on performance and could cause an issue if I forget to defrag and the disk space is filled.
Is this normal behaviour or is this a sign of a more serious problem?

We do receive a huge amount of Spam to a few accounts. Most people empty the Junk Email folders on a daily basis but I would be surprised if it was 1-2GB worth a day.
I stopped NDRs from being sent out to reduce the risk of loops and large queues a few months ago because of the amount of spam to dead email accounts (they no longer exist in Active Directory and the mailboxes have been removed using the clean-up wizard).
There does not appear to be anything stuck in the queues in System Manager but is there somewhere else I should check for a loop?
We receive around 1500 emails a day of which around 200 are genuine. The rest are spam or viruses.
Our deleted Item retention time is 7 days. I reduced it from 30 days when our store dismounted due to hitting the size limit last year.
Shouldn't the free space get used before increasing the size of the database files? Not sure how Exchange works on this score which is why I ask the question.
Thanks

OK thanks for your input.
If it is a possible Store corruption would I be better off migrating the mailboxes to another "temporary" Exchange server, deleting the oringinal store and then creating a new one or would I be better to use some of the tools like eseutil?

Thanks very much for your help. I have implemented the tarpit etc and I think I will try moving to a different server for a week or so and see if the size increase continues, at least that way I'll know for sure where the problem lies. Thanks for your help.
You could also have a corrupt database store which has a problem.
How many emails pass through your system? Do you have a high level of email flow?
What is your deleted item retention time?
