Can't send email to gmail.com

We have not been able to send email to anyone with a gmail.com address.
we can send to anyone else but not them.
we have Exchange 2003 running on a windows 2000 server and we use a company called tcnoc.com for spam filtering incomming email.
We get the following message

Reporting-MTA: dns;mail.baycitymi.org
Final-Recipient: rfc822;kh*********@gmail.com
Action: delayed
Status: 4.4.7
Will-Retry-Until: Wed, 27 Jun 2007 15:19:51 -0400
X-Display-Name: 'kh***********@gmail.com'

 then after a couple of days we will get a failure message like the following

our message did not reach some or all of the intended recipients.
Subject: test
Sent: 6/21/2007 1:54 PM
The following recipient(s) could not be reached:
kh***********@gmail.com on 6/23/2007 2:08 PM
Could not deliver the message in the time limit specified. Please retry or contact your administrator.
<mail.baycitymi.org #4.4.7>

our server has been in continuous use since 2002
As far as I know email from our exchange server "@baycitymi.org" is accepted pretty much everywhere except gmail.com
As more and more people get gmail.com email accounts the problem is growing more and more desperate.
Our city manageris now involved because a commissioner has a gmail account and his email wouldn't go through.
 If you could please help us we would be very greatful.

Do you send your email out through the spam filtering company? If not then I would probably suggest that you do. Use an SMTP Connector to send the email via their service.

we don't have any external SMTP servers only our exchange server sending mail out directly
Our internet DNS entry for our MX record points to the tcnoc.com servers so that all mail from the internet is sent to to them first and then they send the mail to us.
we only accept mail from the tcnoc.com servers. they don't have any SMTP server we can use.

SMTP is for outgoing email not incoming.
Acquire from your ISP tcnoc.com your SMTP server. Usually its in the format of mail.tcnoc.com but you need to check with them.
They are running SMTP servers. Most unusual for a filtering company not to have a server that you can send outbound email through - many of them require that so they can learn what messages you send.

Gmail are very picky about who they will accept email from. If you cannot route through your filtering provider then you will have to route through your ISPs SMTP server.

I put in our ISP's SMTP server (smtp.charter.net) as a smarthost in the SMTP virtual server
and it worked all email is going through
