Is this normal? Or, is > there something in the config file that needs tweaking? You're using a wildcard MX, right? So if someone sends mail to foobarola.wtrt.net, it ends up on your mail host. But your mail host tries to deliver to foobarola.wtrt.net, which doesn't really exist, so it falls back to the wildcard MX, and tries to deliver to itself, and barfs. Solution: Either lose the wildcard MX (my personal preference), or make sendmail on your mail server strip off any host stuff to the left of wtrt.net before processing, so that, e.g., "joebob@foobarola.wtrt.net" gets rewritten to "joebob@wtrt.net" before it attempts delivery.
