Good Morning Mr. Anderson,
I have taken the liberty of answering this email with inline
commetary, just to keep the comments clear, lucid, and on-point: I hope this
is not to hard on the eyes.

I am afraid that *any* open mail relay is against the Savvis AUP.
Commensurate with this Savvis policy, the open mail relay must either be
secured, or taken off the network. Failure to do this will result in
connectivity to this server being forcibly removed by Savvis, through the
imposition of null routes.
> We police its use, and do not permit abuse.
According to the logs you have appended, a great deal of illegitimate third
party email was successfully sent from your open relay, if this is
incorrect, please let me know.

Agreed. Totally. However, this is not a question of law enforcement, it is
a question of adhering to the Savvis Acceptable Use Policy, which is
strictly a ciovil matter, covered only by contract law. As a Savvis
customer, your site agreed to follow our AUP, in order to receive
connectivity services from Savvis.

Open relay is certainly the *easiest* way to support roaming users, however,
it is not the only way, and it is certainly not considered to be a Current
Best Practice. I fully understand how difficult it is to support roaming
users, but a wide-open mail relay is [unfortunately] not an acceptable
answer by itself.

A technical point which I have no argument with.

Please be aware that, while I am not a lawyer, I believe you are
misinterpreting this subsection. 2701(a)(2) is specifically targeted at
unauthorized use, not by blockage under a valid and enforceable civil
contract. Either way, Savvis will competely block IP connectivity to any
open relay on any network under it's direct or indirect control, where the
owner of the open relay refuses to repair the issue him/herself.

These are strictly political arguments which Savvis does not address,
regardless of the accuracy or inaccuracy of the underlying premises.

In short, I urge you to examine other technical solutions for your roaming
user issues [possibly an HTTP interface?].
