# Mail::Milter::Module::MailBogusNull(3pm)

milter to reject null-sender mail to multiple recipients

## NAME

Mail::Milter::Module::MailBogusNull - milter to reject null-sender mail to multiple recipients

## SYNOPSIS

```
    use Mail::Milter::Module::MailBogusNull;
    my $milter = new Mail::Milter::Module::MailBogusNull;
    my $milter2 = &MailBogusNull; # convenience
    $milter2->set_message('Null sender mail should go to only one recipient');
```

## DESCRIPTION

This milter module rejects any mail from a `"null sender"` (empty  `"<>"` address) which attempts to deliver to multiple recipients.   Normal delivery status notifications are intended for a single message, and  thus should only ever be addressed to a single recipient.

## METHODS

**new()**

Creates a MailBogusNull object.  There are no arguments to configure this  module, as it is a fixed check.

set\_message(MESSAGE)

Sets the message used when rejecting messages.

This method returns a reference to the object itself, allowing this method call to be chained.
