Exchange ignoring MX records
Posted on 2004-10-14
As far as I can determine the SMTP service is ignoring the MX preference listed in DNS for some sites? It has repeatedly chosen the highest number instead of the lowest number. Now usually this wouldn't be a problem, but some sites are listing non-mail servers with MX records with very high preference numbers (500). I have checked DNS at the server and it can list MX records all day. How do I make exchange pick the lowest preference?
