There are other more semi-reliable methods. The Sender ID is one of the
groups trying to take a stab at unauthorized services. But having your mail
server do a simple, but thorough reversed DNS check is a better idea. And
make use of the many RBLs out there to track spamming/relay servers. Don't
rely on any ONE thing to fix the problems, especially when Micro$oft wants
to be the solution. :)
It's a bit young to tell all the ways to circumvent it, but I'm sure some
will/do exist.

Subject: OT: Sender ID
Sorry for the off topic but to me, this list is the only good source I know
of to get answers on real life issues as well as the CCIE exam.
Is anyone using Microsoft's Sender ID on the email servers?
From what I have read, this is something that is implemented by the ISP and
will drop emails that are relayed through another server.
I belong to another mailing list that is having some trouble delivering
email to certain email addresses on the list and their error messages say
the mail was dropped due to Sender ID.
Is there any way that you know of to circumvent this problem from either a
client or mail server perspective?
Thanks
John Sheahan
