Chipotle OP MNichols_MA May 15, 2013 at 11:13 UTC Do you send mail through a third-party SPAM filter, or proxy server of any kind? 0 Datil OP dnsconnectordelivery retry L.S May 15, 2013 at 11:18 UTC Need more info. Is this on your Exchange? Restart the Transport Service to start with. 0 Thai Pepper OP whopper May 15, 2013 at 3:40 UTC Agree with more info needed. The problem is probably in a send connector, proxy server or firewall, or in a service having failed. Impossible to know without more dnsconnectordelivery exchange 2010 spam information. Have any of these elements changed lately? 0 Jalapeno OP KMS-IT May 15, 2013 at 9:10 UTC ArunRam wrote: I have lots of mail struck in DNS Connector Delivery queue, no flow outside..organization. Pls help So no mail flowing out?? Do you have successful mail delivery internally? from outside in? As whopper said, i would check all of those areas first. Improper DNS can also kill your mail flow. totally in agreeance; We needz more infoz!! is this your server? (have control over it) server OS? existing server just stopped sending? or is it a new install and hasnt sent mail externally before? exchange version? any bouncebacks? what happens when you clear the queue w / NDR? any infrastructure/hardware changes? DNS changes? lets get these questions answered then we can start getting to the bottom of whats going on! 0 Pimiento OP ArunRam May 16, 2013 at 8:18 UTC Thanks all !!!!!!!! for the response!!!!!!!!!!!

our Exchange 2007 SP1 box running on Windows Server 2008. When sending to this domain, users get a Message Delayed 4.4.7 error and a day later get a final error that it could not be http://www.networksteve.com/exchange/topic.php/Exchange_2007_/_Win2008_DNS_problem/?TopicId=7669&Posts=3 delivered.When I look in the Exchange 2007 Queue Viewer I indeed see:acstechnologies.com DNSConnectorDelivery Retrywith two messages stuck in the queue. My first troubleshooting step was to telnet (on the Exchange box itself) to port 25 at their http://www.computerperformance.co.uk/exchange2007/exchange2007_smtp_connector.htm MX record (mail.acstechnologies.com), which worked, so I went ahead and crafted a raw SMTP message and it got through to them just fine. This proves there is no firewalling or blacklisting going on, I think.My next troubleshooting exchange 2010 step was to get out the packet sniffer and watch the DNS traffic as I did a "retry" on the messages stuck in the queue. This is where it gets weird... the packet traces show NO attempt at looking up the A record their mail server, but instead I see my DNS servers (both Win2008 as well) asking my ISP's DNS servers for AAAA *IPV6* records for this domain, which of course don't exist!I thought dnsconnectordelivery exchange 2010 perhaps the A record was cached and that's why I wasn't seeing it on the wire, so I cleared the DNS server's cache, and also did IPCONFIG /FLUSHDNS on the Exchange box and tried again, but again I see NO lookup for any A record at the specific domain in question and only the bad lookups for nonexistent AAAA records. I posted here as I think this is an Exchange problem more than a Windows DNS one, since I was easily able to ping their domain, telnet to it, and send a raw message (all from the Exchange box) using the same DNS servers.Does anyone have ANY idea what might be going on? We've been running Exchange 2007 for nearly a year without issue, and all other domains (to date) are fine. It is only this ONE that we cannot send mail to.I am at my wits end! February 5th, 2009 3:07am Hi, First please try to check your Domain name with http://www.dnsstuff.com/ to see if it has been listed in the blacklist. Besides, please try to check if we can use other email address to send email to this domain. Please check if you have any spam filter.

How to Configure an Exchange 2007 SMTP Connector How to Configure an Exchange 2007 SMTP Connector The golden rule with Exchange 2007 SMTP connectors is don't do more than you have to. You probably need internet access, therefore by all means configure an SMTP connector to your ISP. However, if you have multiple Exchange 2007 servers in the same site then they can communicate effectively without SMTP connectors. One surprise is that Exchange 2007 SMTP connectors are uni-directional, thus to link two servers, you need one connector to send and another to receive email.

It's the job of the categorizer to deliver the email to the correct mailbox server; whereupon the message is retrieved by a version of Outlook. Routing Strategies For Remote Email Internal to Hub Transport --> Hub Transport different Active Directory site. Internal to Hub Transport server --> ISP Internet Internal to Hub Transport server --> Edge --> Internet Receiving email uses the same routes as above, but in reverse. Thus it follows that you can categorize messages into four groups: inbound or outbound, and local or remote. Because every delivery strategy involves the Hub Transport server, you can appreciate why every Exchange 2007 organization needs at least one server with this role. Indeed, Microsoft's recommendation is to have one server with the Hub Transport role in each Active Directory site.
