Good Morning All, Currently our company has a public domain name (ex. mycompany.com) hosted by our ISP. There's also an MX record (mycompany.com) created on the ISP DNS. We're running our own smtp mail (user@xxxxxxxxxxxxx). Users can send/receive their internal/external mails fine. I'm planning to set up a new mail system for accounting dept users. i.e. user@xxxxxxxxxxxxxxxxxxxxxxxxx Do I have to call my ISP to create a new MX record for accounting.mycompany.com so the accounting users can send/receive internet mails. Can I get away the new MX record. What's my option? Pleas advise. Thanks a bunch, Melvin Chao chaom@xxxxxxxxxxxxx
