RE: [Asrg] seeking comments on new RMX article

["Hallam-Baker, Phillip" <pbaker@verisign.com>]

There is a solution to this problem, a VPN.

I don't think it is necessary to insist that RMX solve every problem. It is
a quick fix that will buy some time, not a long term solution.

The answer to the problem lies in the filter behavior. You do not have to
bitbucket every message that does not have the proper headers, you just
assign a big spambayes penalty so that the threshold for bitbucketing is
much lower.

Also you can take other behaviors like not bouncing.
