Will that actually work?  My understanding, after reading the comments
in the config files said that if you have a message like so:

from: bob at nowhere.org

come see [a href=redir.nowhere.org/someplace]nowhere.org at your
earliest convenience[/a]

That would flag as redir.nowhere.org claiming to be nowhwere.org at
your earliest convenience.

And what goes in the whiltelist file is "redir.nowhere.org"

But you're saying to add bob at nowhwere.org?

I can't in the docs where that's supported as a fix.
