List all files that are scanned.
Should be used together with the --archive option. Set the
maximum number of nested archives (an archive containing
another archive). If the fsav encounters an archive that contains
more nested archives than the specified value, it reports a scan
error for the file. See NOTES -section below about nested
archives.
If the value is set to 0, the archive is scanned but if it contains
another archive, fsav reports a scan error for the file.
The default value is 5.
Enable MIME message scanning. MIME messages are scanned
the same way as archives and the --maxnested option applies to
them as well.
Ignore MIME header anomalies.
Ignore MIME decoding errors.
Ignore errors due to partial MIME content.
