Gregg,

Have you or anyone else out there had any success in setting up the Sender
ID filtering? I guess that is what I really want to try before I try to get
the client to purchase something. Although ORF is something I will keep in
mind.

Thanks so much

Ted

Hey guys,

Was wondering if someone can help with an issue, i have a few users
getting
SPAM NDR's by the hundreds for an hour or two at a time. It seems a
spammer
is using these users email addy and the NDR's are coming in bulk. There
has
to be a way to filter these out and block by checking to see if they truly
originated at the users exchange server. I don't really want to setup a
rule
or turn off NDR reporting as they will never know if a good email bounced
or
not. Isnt there a filter that I can apply to make sure that the NDRs are
in
fact truly NDRs for valid email sent by the user?

all my systems are SBS 2003 with Exchange SP2 and all other pertinent SPs
applied (SBS SP1, Server03 SP2, intelligent msg filter updates etc..)

Thanks for any help

Ted
