SYMPTOMS
========

When you send messages through the Internet Mail Connector (IMC), the following
error message may appear:

  The following recipient could not be reached . . .

This is followed by the e-mail address of the individual you were trying to
reach.

CAUSE
=====

If the Domain Name Service (DNS) administrator has used "wildcards" in the MX
entry for a domain, the above error message appears.

RESOLUTION
==========

Contact your DNS administrator (or your Internet service provider [ISP] if it is
providing DNS).

MORE INFORMATION
================

In many instances, your ISP is also providing the Domain Name Service (DNS)
resolution. This eliminates the need for smaller users to maintain their own DNS
server. However, the problem described here may also occur if your DNS server is
in-house.
