EX_SOFTWARE
An internal software error sendmail exit value
The EX_SOFTWARE
exit code (value 70) indicates that a software error
occurred. For example, when figuring out whether to
speak SMTP, sendmail looks to
see whether the $u
sendmail macro is present in
the A= equate for
the selected delivery agent (The special case of $u in A= on page 740). If $u is absent,
sendmail will speak SMTP. If
sendmail was compiled without
SMTP support (SMTP on page 144),
the fork(2)'d child prints an
error and exits with an EX_SOFTWARE exit code.
Note that the EX_CONFIG (discussed earlier) and
EX_SOFTWARE
errors cause the local
postmaster to get a copy of
the message on the presumption that local errors can
only be fixed locally.
