Assuming that foo1.foo.com is the only machine that should receive mail, you need to do two things: 1. Create an MX record in DNS that looks something like this: foo.com. IN MX 10 foo1.foo.com. 2. Add these lines to the appropriate places in the sendmail.cf on foo1.foo.com: Cw foo.com DMfoo.com The first line will tell foo1.foo.com's sendmail to accept mail for foo.com, and deliver it locally. The second line will tell sendmail to rewrite return addresses so that mail appears to come from foo.com. If you're using sendmail's m4 package for generating your sendmail.cf, add these lines to your .mc file instead of modifying the .cf file directly: MASQUERADE_AS(foo.com)dnl Cw foo.com Forest
