# Legacy Directives affecting Input Modules

## Legacy Directives affecting multiple Input Modules

While these directives only affect input modules, they are global in the sense that they cannot be overwritten for specific input instances. So they apply globally for all inputs that support these directives.

- $AllowedSender
- $DropMsgsWithMaliciousDnsPTRRecords
- $ControlCharacterEscapePrefix
- $DropTrailingLFOnReception
- $Escape8BitCharactersOnReceive
- $EscapeControlCharactersOnReceive

## immark-specific Directives

- $MarkMessagePeriod
