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

milter to check for an IP literal without brackets in HELO

## NAME

Mail::Milter::Module::HeloRawLiteral - milter to check for an IP literal without brackets in HELO

## SYNOPSIS

```
    use Mail::Milter::Module::HeloRawLiteral;
    my $milter = new Mail::Milter::Module::HeloRawLiteral();
    my $milter2 = &HeloRawLiteral; # convenience
```

## DESCRIPTION

RFC2821:4.1.3 specifies that raw IP addresses may be used in HELO, but only if they are enclosed in \[square brackets\].  Spam engines sometimes forget the brackets, so this milter will catch them.
