SMTPDIAG resultsran the SMTPDIAG tool on the Exchange server and these are the results I got below: Can anyone help by telling me what error 10053 is and how to solve this problem ? Many thanks in advance: C:\Program Files\Exchsrvr\BIN>smtpdiag "administra***@nakedcomms.com" "paddy.ad***@chiadvertising.com" Searching for Exchange external DNS settings. Computer name is EXCHANGE1. VSI 1 has the following external DNS servers: There are no external DNS servers configured. Checking SOA for chiadvertising.com. Checking external DNS servers.

this manually or did you run SMTPDiag again. I just connected to mail.chiadvertising.com without a problem.

The strange thing is that some users can send fine and others cant. The users that seem to be experiencing these problems tend to be using Entourage on Mac's. When I look in "Message Tracking Centre" in Exchange system manager it looks as though they have sent each message 6 times. This also happens when they send an internal meeting request as you receive it 6 times. I hope this gives you more info. Many thanks again Can you confirm how DNS is setup up on your Exchange server. Also, how are
you routing email within and from Exchange?

Network (192.168.x.x) and the secondary is a DNS server of our ISP. There are no external DNS servers configured on the SMTP server as I used to have them in but we still had the same problem. >From our Exchange there is a smart host which sends all our email out to messagelabs first.Thanks again Have a look at this.
