At this point if I where you I would open cmd.exe (command prompt) and run nslookup.exe See what the type=mx answers for domain csdcso.on.ca
Make sure the IP number it returns is correct and the DNS you are connecting to are the ones you are suppose to connect to. Nslookup will give you a lot of answers and ideas of what the problem is. If you see something rare in your NSLOOKUP answers try the same with other domains to make sure the problem is just with csdcso.on.ca. Make sure the DNS's your IMAIL server is using are right and properly configured (have the correct IPs) Are you running any packet filtering software at your email server? Sometimes closing some ports causes trouble with DNS and IMAIL. That happened to us a few months ago. If you are running packet filtering software I will lookup to see what ports we opened to solved the problem. Is your DNS in your same Imail Box? Perhaps is there any interference? According to a nslookup I did to a local DNS, here it is what csdcso.on.ca answers csdcso.on.ca A 207.236.219.66 csdcso.on.ca MX 1 outlook.csdcso.on.ca csdcso.on.ca NS dns1.csdcso.on.ca csdcso.on.ca NS dns2.csdcso.on.ca dns1.csdcso.on.ca A 207.236.219.33 dns2.csdcso.on.ca A 207.236.219.34 Have you try the first lesson in the book. Stop and restart services.. perhaps even the server and see if error continues?

The problem here is that you've encountered the IMail "Using-the-A-record-instead-of-MX-record" bug. You should upgrade to the latest version of IMail, which hopefully will fix the problem. Specifically, the version of IMail you are running may use the A record under certain circumstances, even when the MX record exists. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers.
