Messages stuck in Local Delivery Queue

[New Mom]

I’m using a SBS 2003 SP2 with Exchange 2003 SP2 installed. We have few clients connected to this server. The problem is I can see about 60 emails queued and in the Local Delivery Queue. One common thing in all these stuck messages is the recipient is the one same person. I mean, these messages are sent by different senders and receipt is same.

When we checked we found the recipient of these stuck mails is able to send and receive mails without any problem. Then why 60 mails are stuck in the queue? Is it something have to do with SPAM filter on the recipient's Outlook?

Nope, it doesn’t have anything to do with SPAM filter on the recipient's Outlook. problem is something else. By the way , did you tried forcing connections on the Local Delivery Queue? Did it help?

Yep, I tried force connection and unfreeze. I even restarted SMTP connection but still the same result.

What now?

I think this is the exact problem I faced couple of months ago and in my case I called up my ISP, told them to change the DNS server addresses. That’s it. Problem solved. So you need to find out the right ones and re-run the Internet Connection Wizard....
