EX_CONFIG

A configuration error sendmail exit value

The EX_CONFIG exit value (the value 78) means that a fatal configuration problem was found, but not necessarily while reading the configuration file. Failure of a delivery agent to function correctly can lead to this kind of failure.

Note that the EX_CONFIG error and EX_SOFTWARE error (discussed later) cause the local postmaster to get a copy of the message on the presumption that local errors can only be fixed locally.
