Hi Larry - when you say "Your dns report and your sorbs report were both
clean", what exactly do you mean? What is clean? Does this mean that my
server could not be used as a spam relay?

Your dns report and your sorbs report were both clean, so you may just be a
victim of a spoofer. You do not have a spf record for that domain.

Post one of the messages.

Hi Larry,

Thanks for the reply.

My domain is at dgsteinconsulting dot com.

The public IP address is: 68 146 16 140


Also, I just looked in my SPAM quarantine and there were an additional 400
email replies from destinations sent from my domain.

Thanks.

Hi SpinalTap:

If you post your email domain name, that is the part after the @, we can
check it for you. Disguise it as in *at*my*company*dot*com (remove the
stars).

There are a number of things that can go wrong. One that just happened
to a
client was that he allowed the shop workers to use the wireless side of
his
router to use their notebooks at breaks and lunch. One or more of them
was
infected and his IP was blacklisted, even though it has nothing to do
with
his domain name.

Therefore the public ip address of your wan facing device would also be
helpful.

Here are some articles about checking for relay, but SBS/Exchange is not
setup to relay unless your administrator specifically changed the
settings.

I would be much more likely to suspect some other issue. shoot us the
domain name and the ip address and we can check, or you can use
www.dnsstuff.com and www.sorbs.net to run some checks yourself.

Hello,

I am not exactly sure if my SBS server is acting as a SPAM relay but
what
is
happening is that I am receiving a bunch of replies from destination
email
addresses. These replies are indicating that messages from one of our
accounts have been blocked, and the subject indicates that it is
definitely
spam. This started happing today, and I have not made any significant
changes to my configuration.

Is there a way to determine if I am acting as a relay? Also, we only
use
RWW for accessing email (i.e no POP3), but we do access other POP3
accounts
from other mail services. Given that, what can I turn off to reduce
the
chance that this can happen.

Thanks in advance for any insight.

-Dean
