you mean, the mail will find the server with priority search on MX record, until find match domain. in may case below, the mail will go to B.com with aaa.com without bounce back e-mail cause the domain not found in A.com with bbb.com ? ----- Original Message ----- From: Robert Abela To: [ExchangeList] Sent: Wednesday, June 26, 2002 5:53 PM Subject: [exchangelist] RE: DNS & Mail Server http://www.MSExchange.org/ - Re-Vamped!

Hi, We are a newbie in DNS and mail server. We have 2 mail server, both installed exchange server 5.5 sp3. We want to know, there is a domain aaa.com, if in the DNS record for aaa.com : MX 10 A.com MX 20 B.com and there is first mail server (A.com) with domain bbb.com and second mail server (B.com) with aaa.com. When an e-mail sent to domain aaa.com, what will happen with this e-mail ? Thanks.
