exchange not forwarding anymore

i recently moved our network to our new offices and everything seems to be working fine except one small anomaly. It seems that our email is no longer forwarding to personal accounts as it used to. has anyboidy experienced this before?
we are using windows server 2003 running exchange server 2003 and i have forwarding set up on the server using the "forward to" and forwarding to a seperate contact that is set up in active directory.
forwarding is allowed under the esm global settings.
has anybody run into this problem before?
thanks.

I am not sure if I understand you correctly. You have configured a forwarding address in the internet for each of your mailboxes in Active Directory? Sorry, I cannot imagine why this would not work anymore after only moving the office. I assume mail to the internet works. So why should forwarding not work. Can you send e-mail to the forwarding address directly?

we have a few users that have email forwarding set up for them (myself being one of them).
if i look in the queue i can see approx 257 msgs waiting to be sent to gmail.com.
i can send fine to gmail / internet from outlook.

What does it say at the bottom of the queue window relating to failures?

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

it says 'smtp could not connect to any dns servers'
i checked the network connection and tried a couple dns servers (internal & external) to no avail.
although i can ping the dns server just fine.

did you try opening a command prompt and typing nslookup
then type set type = mx
then type google.com

This return google.com mail servers.

ok i used nslookup and it returned googles mail server addresses.

it looks like forwarding is not the entire problem (although it is still not working)  but it seemed to have stopped working when we moved and all our mail was being mail bagged. anything that was delivered and was being forwarded is now just sitting in the queue.
they all have (SMTP Connector) next to the domain in the queue and the error on the bottom still says 'smtp could not connect to any dns servers'

Give a try to forcing the connection in the queue manager and see if that gives any success.

i have tried forcing in the queue and also unfreezing. neither of which worked.

Can you send any mail normally to those addresses at google?

-pHAuthor Commented:
yes, i can send fine to those addresses which makes it even more confusing.

Check out the following setting:

In ESM go under global settings, internet message formats, properties of default, under the advanced tab.

What check boxes are checked down toward the bottom.

Is Automatic Reply and Forward checked?

-pHAuthor Commented:
yes, that was one of the first things i checked before posting.

Why dont you try clearing the queue if you are ok with losing some of those emails getting forwarded.  I assume a copy exists in the mailbox.  Then try sending to a mailbox and see if they go through.

ooops, that should have included... all boxes are checked on the bottom of that tab.

unfortunately i can not lose the emails in the queue. a lot are from external clients and business partners destined for our ceo.

MATTHEW_LCommented:
Ah.  Not good then.  All of the boxes being checked is ok, that config should work.  Have you tried restarting exchange services, reboot etc.?

Just another thought you are forwarding to contacts correct inside of ADUC?  Make sure that the contact is setup correctly with the right email address no typo's etc.

Since system manger is complaining about DNS, you may try an ipconfig /flushdns, or clear the cache on an internal DNS server etc.

all the contact addresses in the AD are correct.
i have tried multiple reboots and restarts of the exchange services.
clearing the dns on the servers also didn't help.

ok, for anybody following this here is the update...
the reason we could send to gmail in house and not from the queue is we had our smtp server on local machines set to use our isp's smtp.
the problem on the server itself was fixed by editing the 'smart host' to reflect the new isp's smtp server.
