An exit value of
EX_CANTCREAT (the value 73) means that an output file could not be
written to. This error generally refers to a user-specified file
rather than a system- or configuration-file-specified file. For
example, an attempt to write to a file that has any execute bit set
in its permissions can yield an error, as can a file that has more
than one link, and (if the SafeFileEnvironment
option, SafeFileEnvironment, is set) a file that is not a
regular file. Note that some problems can lead to this error, without
printing an error message.
If the SafeFileEnvironment option is specified and
sendmail is unable to
chroot(2) into the specified directory, the
following message is logged:
mailfile: Cannot chroot(directory)
When delivery is to a file, sendmail will log
the following error if the file cannot be opened or
stat(3)'d, and the
fork(2)'d child will exit with
EX_CANTCREAT:
cannot open: reason here
cannot fstat: reason here
