Hi all, Iam using a dynamic Ip (dialup) and have exchange server installed on my win2000 domain controller. I have registered with noip.com and my domain name would be deepblue.bounceme.net (deepblue is my hostname)ping by name works fine. Now for entering the MX record i have a doubt. In the noip page information it shows as two sections. 1) Hostname :deepblue.bounceme.net Host type: Dns host (A) Ip address:my dynamic ip 2) Mail options Enter name of your external mail exchangers(mx records) MX Record MX priority ????? 5 Here the question mark i have to fill up******* . My question is "should i have my MX record already with another ISP? if not what should i fill up? MY computer name is deepblue.raj.com By the way i can send email fine!!. --------------------------------- Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software
