I recommend that you start checking your nameserver first, with dig any domain.com, for example, or nslookup. In the answer there must be something like domain.com. IN MX 10 server1.guru.com. If you do not get it, your nameserver is misconfigured, and your MTA (sendmail) does not know where to deliver mail for domain.com. Once more: 1. nameserver authorised for a certain domain (e.g. domain.com) defines WHERE mail for this domain should be delivered 2. virtusertable maps virtual users to local mailboxes.
