This is intentional in the suggested-minimum-filter-for-windows-clients
filter found in MIMEDefang 2.38 and below. In MIMEDefang 2.39, the regexp
in the filter was changed because so many people were complaining about that
exact problem.
# Do not allow:
# - CLSIDs {foobarbaz}
# - bad extensions (possibly with trailing dots) at end or
# followed by non-alphanum
$re = '\.' . $bad_exts . '\.*([^-A-Za-z0-9_.,]|$)';
became
# Do not allow:

$re = '\.' . $bad_exts . '\.*$';
