[BlueOnyx:01704] Archive Email

[Gregg]

Hello,
I have a client that would like to start archiving both incoming and
outgoing emails.  I was wondering if anyone has any suggestions on doing
this with a blueonyx as an email server.  I've looked into some off the
shelf items, such as the barracuda email archiver, but those cost quite a
bit of money, and it's not feasible for a small start up company that needs
archiving.
Thanks for any suggestions.
