Migrating archived email from Barracuda Message Archiver to EVault

Hey Guys:

I am trying to find a way for Enterprise Vault to suck in a PST file that I exported from a Barracuda Message Archiver.  The PST file will have emails from multiple To: addresses.  As far as I can see, the server side PST migration tool just uses permissions set on the PST file to assign the archive.

Ideally, I would just want to point to the PST file and off it goes, putting the individual emails into their respective archives.  Please let me know if this is doable or if I am looking at exporting the emails with the same To: fields.

Thanks
