OT - Recipient verification

[Brandon Checketts]

We currently dump out a list of valid users to a plain text file that is shipped
over to the mailscanner box periodically and imported into a postfix transport
file.   It works, but I don't like it very much, so I'm looking into
implementing a postfix transport database via MySQL which should do what you want.

Thanks,
