RBL and Exchange 2007
I have a hand full of users that have outside reciepents that bounce back emails sent to them and the error details note 'Message rejected because of RBL policy'
We are running Exchange 2007 and using Vipre (from GFI) for spam filtering. When I run our mail server IP on the blacklist check found at http://www.mxtoolbox.com it comes back clean.
My question is two fold...
(1) Could it be that we are listed someplace else that http://www.mxtoolbox.com does not scan again and if so is there another tool I should be using other than http://www.mxtoolbox.com?
(2) I am under the assumption that I am only relying only on GFI's software for RBL purposes but is it possible that I have it also setup in Exchange? If so how would I check?
Not sure if it matters any but the bounce backs all seem to come from users that have Google for email

FYI - Vipre is Anti-Virus not Anti-Spam. Are you using GFI Mail Essentials for Spam Filtering?

Thanks for this input. I will send you a test email right now from the admin account. I did update the FQDN in E2007 a couple of moments ago. I thought I already did this but it looks like I was wrong in that assumption.
The Vipre product we use is both for anti-spam and anti-virus.
Thanks for this helpful input.
ASKER
Ooh - sorry about the Vipre - didn't know they did a combined product. We use a Vipre based solution from them and wrongly assumed it was only AV! You live and you learn :)
Okay - test email received. Checking your config to see if anything stands out as being wrong.
ASKER
All good. Standing by. Thanks :)

On the FQDN, maybe I need to restart the connector before the change takes effect (?). I will do that later and send you another test. I see your point in making certain both are mail.domain.org
Understood on the MX record.
Any recommendation on setting up a SPF record?
Thanks for all of the support

All good. I will restart the transport now and send you one more test message.
Okey dokey.
Still seeing exchange.domain.org as FQDN.
ASKER
Maybe I need to reboot the server (which I can do tonight)?
and/or
Maybe I am not doing the right thing to setup the FQDN? Here are screenshots of the connectors with what I think is the right FQDN setup, Is there something I am missed?

Got it. My mistake. I just updated (hopefully the right way this time) and resent another test.
Thanks for all the good tips.
That's better. Seeing mail.domain.org now.
Try sending emails to the recipients that failed before.

Do they match? Do they both resolve in DNS back to the IP Address you are sending from?
If you are not sure - send me a test message to alan @ it-eye.co.uk and I'll see what you are sending as, what IP you are coming from and I'll see if I can see any issues with your setup that might be causing you problems.
